You are doing some very important work to keep the manufacturers on their toes by testing their products to the limit! Thank you for this great service to all people who are interested in solar power and storage.
Mate they would fake everything, there are almost no new A batteries available for consumer to buy. All new batteries from manufacturer is sold in years in advance, everything else is repackage B/C and refurbished A from ev. That information comes from people on the manufacturing sites in China and im impressed by naive approach of everyone just reading manufacturer specification and believe in it.
Hi Andy! Awesome that you do this test of the Gobelpower pack! I just finished my DIY build of the smaller version of this pack (150A Refinergy BMS). Gobelpower was so kind to sell me the metal case, BMS, etc separately so I could do an upgrade of my already existing 8S EVE280LF pack to a 16S pack. The only modification I did was installing a NEEY 4A active balancer instead of the Heltec balancer. Support during ordering and even aftersales was great. The BMS I got had a problem by measureing on cell voltage and showed strange values. After contacting the support it was identified that the BMS was faulty and Gobelpower send me a new BMS free of charge which arrived after 6 days. Top service! Everything is working now and I‘m more than happy with my battery pack! 😊 Looking forward to your tests now and I‘m highly satisfied with the service Gobelpower has provided me! ( And no, I‘m not paid to write this, I‘m only a happy customer who paid all by myself) Cheers Jens
Whilst one would praise the after sales service it would have been much better for them to send the correct working item in the first place. So now the idea rests vaguely in the back of the mind that these people were taking chances - hoping you wouldn't notice the faults and just install it and ruin your battery. That is how reputations are ruined - either by not testing products or deliberately taking chances, hoping to save money.
Thanks for sharing, Jens. That is great service. I think they were considering selling these cases separately for DIY projects. I have to chase this up. It's a great alternative to the Seplos Mason cases (but they come with the 10E BMS which is far less optimal than the Pace BMS). I think it is great service of them to do troubleshooting with you and replace the faulty part so quickly. That's the service we need.
Great. Andy got the same battery I have got 5 months ago. Love it and many thanks for testing it. Got it with 40% SOC and nothing changes after month of no use.
Yeah, mine arrived with 37%. Jens had the predecessor on his channel a while back with a huge discount. Do you have the active balancer already as well? I thought this is a fairly new feature.
Just got my Gobel Power Battery. It took about 2 months shipping from China to Germany. I used prepayment via wire transfer and everything went fine - you get a tracking number and can see the state f your shipment at any time. But GP seems to not use the Neeeeeeeeeeey anymore with the 4A Bluetooth option. I got a Heltec 4A Balancer. Bluetooth name is EK-24S4EB. I ordered the Basic option and it has 278 Ah at 42.31V - 56.64V during the GP tests. Delta V is 0.003 V at 40% SOC after arrival.
As you are in the last month of Winter we are in the last month of Summer. Days are getting shorter fast. Only have 50KW of battery but plenty of PV. Weather is in the 100 Degree range (37C) for the last week so AC units running full on. Due to short days the batteries go down to 30% every night. Looking foreword to some cooler weather next week. Keep up the great videos and thanks.
@OffGridGarageAustralia Think so. Have 18500 watts PV, so always get some solar, but we do have times when it is heavy clouds for a week. Nice auto start generator if needed.
From my table for single conductor in free air for aircraft wiring, a 3awg wire @ 300Amps the temp rise is off the table which has a 100deg C upper end. I have extended the curve looks like some where around a 150deg temp rise above ambient. Fuse and thermal runaway comes to mind. Copper has a 0.3% resistance increase per degC.
It’s came a long way in the last few years. I can’t wait to see what is available in the next couple years. When I bought these types were not available.
Hi Andy! Really, really interesting this Gobel Battery Pack! -No welded cells! - Good, perfect information and transparency, about the cells and the material, used for the pack! Really amazing ! - Gobel would then be the only ones manufacturer to have understood, what these potential customers want? Well done ! In any case Thanks again Andy, and we are impatiently awaiting the test of the pack! 😁 Because It's true these Balancer all the time ON?? we will see ? Thanks to you Andy,😊
Yeah, they seem to have listened to the community. Also have a look at the second video about the capacity tests and the BMS settings. Really interesting.
@@OffGridGarageAustralia agree but want to understand how that active balancer is working. Your software said that active balancing started at 3.45V per cell but you are observing it sooner? Do you have current draw on the balancer cables?
based on SOC your winter season is long gone . I had totally forgotten how many batteries you already have , but no clue about the capacity but I would guess about 90 kWh, so a day in your life without the grid and fully charging your Tesla - out of the battery. Sooner or later you will become a neighborhood power supplier. Next review point will be a grip test for battery wheels and a 40 lap test race between all your batteries on wheels. I guess reviews will then take longer. 7:30 is a nice service about the built and configuration incl. brand and model of the cells plus quality. And of cause the capacity plus max Volt for your battery to check it. But test done July 1st means that shipping to Australia might not have been so worse. 10:49 - I love this kind of communication what has been ordered and what it mean regarding quality. Great progress I have to admit if they will deliver what they promise but gobel was also the company with the QR code transparency. ANd if they will perform that way for a few weeks and tests I bet all others have fallen behind, lot behind. But I still love the Frankenstein adventure a lot cause it is closer to us averages users that do not buy grade A.
I already generate all the power I need including hot water and EV charging. Crazy! This is all thanks to the large PV array on the garage and car port. I have not connected any of these batteries to my battery shlef yet. The overall capacity would be around 2700Ah @ 51.2V. I will probably never connect them all to my system. Most are just here for testing, to learn explore and share. Yeah, a few laps on a battery race track would be great😂 I also like the transparency Gobelpower shows in regards to these batteries. It is really great, that they step up the game and be at the forefront with such a system and database. More Frankenstein videos coming...
It's more than clear that every (Chinese) company need a Andy Quality Controller 😉 You wonder why they don't watch and learn from his channel. Still no perfect battery available... Insane! 🐸
Yeah, all the info is out there. Many tests online. Someone just need to watch, take some notes and start building this perfect battery. It's not hard.
Yay, another video, faaabulous, great stuff- thanks Andy! 👍👍👍 You’ll soon have enough energy stored to go for weeks without sunshine 🌞 (This battery looks awesome!)
The battery? Would a DIY battery not be more suitable so you can custom build the case to fit in the bus? I would assume you need at least two batteries?
It has such an input, yes. You can solder two cables to this and use an external switch for example. Or the voltage trigger as we have used in this video. It is then fully automatic. ua-cam.com/video/kEeD-oM4QnY/v-deo.html
Hey Andy, I was just reading some news, and it looks like a company making LiFePO4 battery packs for cars has come very close to achieving energy density parity with traditional lithium ion battery packs made using 18650 or 21700 cells. I really hope this new technology ends up shrinking the size and weight of the current LiFePO4 cells on the market now, or maybe you will be able to get 400Ah into something the size of a LF280k. I also saw the 1st factory being built that is supposed to start producing solid state batteries as well. Those should have fairly big improvements over all of the different lithium chemistries we have now. I'm Excited to see what the solid state cells can do, and if they will have any big flaws, like being really fragile because of the porous ceramics they were using as a solid electrolyte. Let us know if you find any big news like this in the future! I'd love to see LiFePO4 with a new electrolyte or some anode and cathode improvements.
Yeah, all these news around new battery tech. Only 0.001% will make it into production. I have stopped reading that stuff. It's all theoretical and test in laboratories. As soon as there is no facility with serious production lines, the tech you read about will most likely not come to market. Solid state... that's a good example. Promised for the last 10 years and still not here. LiFePO4 is great and will be around for a long time. I have now some Na+ cells here to test, but tech is not there yet and no serious production lines. This may come though over time for this technology.
There are multiple variables that determine the ampacity of any given conductor besides cross sectional area and the material from which it is made. Obviously insulation temperature rating, but also ambient temperature, free air vs inside a raceway, single or multiple conductors, and temperature ratings of the devices to which the conductor connects. But, for the sake of making the battery more efficient, I'd sure like to see heavier cables.
Yes, correct, the installation method is important too. We're just checking roughly here if the cable is the right size. Chinese batteries always save on copper. They could have just added a third 7AWG wire for $2, would have sufficient cross section for the breaker and nobody would even question it. However, I'm not expecting anyone pulling more than 50A from such a battery for an extended period of time. That would be bad system design.
What is included in the delivery? Handbook is a bit confusing. Handbook chapter 3 "Scope of Delivery" states - battery, - wall mount, - 2x 1m battery cables and screws, - 1x inverter cable D1 and - 1x PC-RS232-USB cable D2. Later it stays "not included" D1, D2.
Maybe these are LF280K V3 cells. Those cell terminals (oct-shape?) do not match the LF280K V2 cells we got so far. Also SunFunKits states they test between 290 and 315 Ah - but they use their own terminals/studs which they weld themselves.
Yes these are the new LF280K V3 cells with octagonal terminals. With my last order from Gobel (just cells only) I got them too. I'm still testing the capacity...6 cells are done: 305-307Ah with EBC A40L 3.65V->2.5V 30A.
The BMS can handle 200A in both directions. I would not recommend it to protect the batteries. If you have such high currents, get a second battery in parallel.
6.30 is a choral track by Libera! Think its Vespera but could be wrong! Here for the battery’s but been a fan of `Libera since the 90’s when they where called St Philips! Battery and choral geek out in one video! 😂❤
Are there any concerns left where you would say, do not buy yet and wait for my next video or xyz test ? I can remember that you were not so happy a about a cable which consisted out of 3000 tiny single wires where they said they wanna test it with a 300 A current. But anything else worth to wait for ?
Whilst their attention to detail is impressive, I must admit that at these prices, I feel it's almost equal to a big-name brand solution. You can get an LG LGES-5048 + LG RESU 12 LV bundle for ~10k AUD. The LGES-5048 is effectively a rebadged GoodWe with greater capacity, and a really nice hybrid inverter, worth 2k+ alone.
@@OffGridGarageAustralia I've been trying to save enough $$, to get a few good panels and some decent size batteries for MT year round job as an equipmentwatch/firewatch . for some reason, these last 3yrs, I haven't been able to save any $$. It must be the price of toilet paper and having to deal with so much 💩💩💩💩💩, here in the US... I've been using 2, now 5, lead acid deep cycle batteries, with a little 400W invertor & 80W panel. The invertor shuts off at around 11v, which has likely kept my batteries from dying too quick. I was running a basic 3500w generator, which ran 11hrs on 4 gallons of gasoline. I was lucky enough to get a 2000w generator that goes 12 hours on 1.2 gallons at low load and it goes 8hrs on full load It has helped cut fuel costs down, but,,, a few good panels and better batteries, plus a better invertor would probably pay for itself by not burning expensive fuel. I don't buy ice anymore as I have a small chest freezer and freeze bottles of water, for the cooler, to keep food cold. I have a 5kw AC unit, to keep me and my almost 4yr old RottnLab cool, during hot weather. It would be nice to be able to operate the chest freezer and AC unit running on solar/battery power, just using the generator occasionally, to keep batteries charged.😎☕
Very well put battery but not to be used in powerwall mode, I don't like when the cells are not upright, concerns me that electrolyte won't be in bottom of the cell. Andy what is your opinion on that?
It is not a problem at all. The cells are fully compressed and there is no air in these cells, so the electrolyte wont settle on one site. As per manufacturer specifications, these cells can be used in any orientation except upside down. If they are not upright (terminals pointing up), I would highly recommend compressing them though.
Andy how much Battery Capacity do you have now in service ? 110 KW/h ? Are you going to build a "new" Battery Garage ? When will you test Natrium-Ion Batterie Cells any hope ?
Still running the 44kWh in the battery shelf. None of the other batteries is actually connected right now. All for testing purposes only. I'm working on more storage though as well as on more solar... 😉
This looks like a very good design to me. Do they have anything smaller? If I were to install home batteries, they would need to go up some stairs. Or maybe some really long DC cables from the planned hybrid inverter upstairs, but that's going to be a challenge as well. Someting modular in luggable parts of 25 kg or less would be better. Or maybe something with a hot swap bracket system, so you can add or replace individual cells as needed, just like computer data storage systems. Minimum combined voltage and matching capacity may be an issue there, but just ordering a new replacement cell module is much better for the environment compared to replacing (and transporting) the whole system.
@@OffGridGarageAustralia Maybe you can ask them for a modular version? They seem to be listening to your other suggestions, and scaling down such a design should not be too hard for them, judging from the excellent quality. Something small and stackable would be great for the people without a garage that doubles as a power plant 😂
Just having a think on the balancer being a little too active I do wonder if there is a way to use the DCT to turn on the balancer, I'm sure the trigger will be easy to work out, but on the balancer side...? I'm sure it wouldn't be too hard for you to DIY a way to fix this over active balance issue side note, one of my jk bms reads the voltage 0.2 volt higher than the rest and Ive learnt today what issues that can do with trying to balance on the flat part of the voltage, I know I can change it, but for now I want to see exactly what it will do long term
Not hard to do at all with the voltage detection controller as shown here: ua-cam.com/video/kEeD-oM4QnY/v-deo.html Yeah, these long term tests. I have many of them running 😂
First thing I turn off is the auto reboot or reboot at night. All other programs like browser and file explorer were still open. It was a stuck Win update though, which I didn't bother fixing.
I really like when a manufacturer includes a circuit breaker and not just a fuse. It'd be nicer if they'd put the fuse in an easier to access location given it has a lower current rating than the circuit breaker, but otherwise the hardware looks really well put together
The battery is rock solid built. I'm really happy with what they have put together. Hopefully, you will never have to replace the fuse in this battery. I think it is fairly accessible once the front panel is removed. Also with a ratchet extension, the nuts can be removed from the top.
@@OffGridGarageAustralia It really looks like a great battery, watched the follow up with the charge and discharge tests and it looks really well put together with high quality cells I guess the breaker probably functions more like an isolator, since the fuse would pop long before it does One other minor niggle, I find the soft reset button on the BMS annoying. I'd much prefer a rocker switch or something to disconnect the BMS power supply When I switch something off, I want it to be OFF 😁
Hi Andy. Thier DIY kit with your code is a good value kit of bits, not much more than I have spent so far sourcing all my own components. 😂😭😭...... Not including the shipping to me in Scotland though. FOGSTAR UK Can't be beaten for that! As always love from 🏴 Gaz
Excellent seen the CE label nice I love seeing these new setup but like to see more Aussie built batteries but they should watch your channel we will get there lol still I like to see a cell in a fire and a starpicket pierce test hahaha(I know the result you be surprised their safer than you think)
I'm not aware that anyone in AUS is building such 48V batteries. They all import from China anyway afaik. Would be good though if we could get them locally.
I just went to lithium batteries “260ah x 2” I accidentally shorted one out hooking them up. I charged them up at the same voltage. The battery shorted did shut down, :-) it had to be woke up. This batter is the head battery in my parallel system. After a few days of use this batter is at a lower % than the other battery. The voltage is holding even on both batteries. Do you think I might of hurt the shorted out battery?
Charge them both up to 55.2V and they will balance out again. If the short was only for a split second, there is no harm. You have to be more careful when working with these batteries. Always take a cloth and cover all the surrounding terminals so this cannot happen.
@@OffGridGarageAustralia Ya I was careless “the BMS seemed to instantly shut off” think you so much for your reply I’ve been freaking out do to just buying these batteries 🫨. I think it was you that said you can’t get a mid point %. On parallel wired batteries 🤔. It was showing 99.80% deviation 🥴. So I turned it off on my victron battery monitor. So I would quick worrying about it.
What is the recommended Grid Amp setting for this battery? I see in the video says max 140A in the specifications sticker but what would be the recommended setting? Thank you
Heya, that are some good cell's I believe 297Ah wouw nice. I received my 16 lfp4 cell's they clame 320Ah but the first 2 battey cell's have 297 and 293Ah (tested with the the EBC-A20 tester) so I gues they are 280Ah cell's. still testing the other 14 cell's as we speak will upload a vlog about the testing.
This battery box looks very interesting. I actually only miss the version without batteries. Is there such a thing? Or another brand that uses the PACE BMS.
Hi Andy, I am really keen on seeing your findings about the batts that I own for 1 month now.. So far my impressions are identical to yours: Good quality!
I am a Fan of your work :) how it the progress in balancing the Seplos battery? my Frankie battery getting progress in top balance but still have 3 cells rushing back to under 3.37 when charging current drop under 4 amps.
Nope, the Seplos V3 will not balance over time...but it would work with the 10C or 10E BMS. My Gooble Power 280Ah Pack has still the RN150 Refinergy BMS...it does not balance well...but seems like they resently upgraded that to Pace entirely. I am curious to eventually test the Pace BMS myself...maybe we can adust the settings in a way, that they don't even need the active balancer anymore...
In this point, I have to disagree with you...they are both switching off the charging MOSFETs, once it resets to 100% SOC. So you first have to discharge the battery (to 96% I think) to be able to charge it back up.@@OffGridGarageAustralia
My limited understanding is that these types of silicone high amp cables rely on being able to heat up safely while delivering the stated amps. Please correct me if I am wrong. If this is true, then the cables will be hot and we want to remove any extra heat in the system. Increased heat equals increased resistance, again limited understanding and happy to be corrected. We want the system to run cool even if under load continuously for the full capacity of the battery. I want to apply the same thinking to those busbars which seem under specifications for an environment with no airflow. I hope someone out there in the community with more knowledge can reply and shed some more light on this subject here.
Andy, the *Cable* (insulation) might be able to withstand high temperatures and therefore operate up to 240 ARMS. BUT what is connected to the cable & cable lugs is typically only rated 60-75°C (in some cases 90°C). You typically see this indicated on Switch Disconnectors, Breakers, etc. "Use only 60-75°C Cu (Copper)". You don't want your hot cable heating up what it is connected to (Breaker, Cells, ...). Actually the cable should be a thermal sink pulling the heat away from the breaker, NOT the other way around.
Yeah, good points. I don't know if people really pull close to 200A for an extended period of time from such a battery. I think this is bad system design and these guys need a second battery in parallel.
Really enjoy the humor in your videos Andy. Nice to see Gobal using the new style 280AH cells with the hexagon terminals. They seem to test so much better in Ah then the older 280Ah cells. With that said, fu*k B cells lol. I can't imagine using a B cell for my customers. This sort of BS is why I build the batteries for my customers.
Side note regarding the end of the video, I stand by my statement from over a year ago, an active balancer is only necessary when you first build a battery to speed up balancing. You do not need it after that.
Hallo Andy mich wundert das dein Pack keine 2te Sichereung hat. Bei mir sitzt sie genau nach 8 Zellen eine Sicherung als Brücke zwischen den 2 Batterien Reihen. Meine batterien sind von Jan/2023!?
That is the 'older' design battery. The SR1-PC200 has one fuse and a breaker in line with the positive. Your pack has also the 150A Gobelpower BMS, I assume.
Andy, I just pulled the trigger on the Gobel "standard" pack. The rest of my system is old school but operating just fine. Outback charge controller and AIMS 48v inverter without a comm port. Will the Gobel operate just fine or is there anything additional I need for monitoring? Ex. Victron BMV-712. Thanks in advance, PROST! Scott in Las Vegas, NV
Nah, all the other programs were still running (web browser and file explorer). There was a Win update stuck for weeks and I didn't bother fixing it. I did now and it seems to have solved the issue. Auto restarts are turned off in all my systems.
Ok, so i now want this enclosure, same batteries, 250A charge and discharge bms, 75mm wires, screw terminals and my own neeeeey 4A programmable balancer 😂 Can it be done?!
This actually seems like a good price for these (with the discount before shipping) Now if I can only convince the wife.... lol I'm looking forward to the full test. I wonder how much worse the "DIY" kit is vs the "A" Too bad they didn't send you a DIY one as well.. But my guess is they cherry picked a unit that had above average cells for you to review!
Yeah, I wish they would have send me a DIY battery. I would not worry about it and take the DIY Kit they offer. With the active balancer in place, it will sort itself out. It's in the next video... and for US$2600, it's a bargain!
Gobel power HSEV 280 AH cells are on sale, and are a pretty good deal...When you read the description, it explains the "B" on your cells, they say that they are ESS cells, but to test that good, it's confusing..Apparantly EVE now prints a "B" on ESS cells so that they cannot be sold as HSEV cells...Because they cannot be distinguished from each other, in any other way, other than the paperwork which could be forged..That is what it explains on their website when you click on the raw EVE 280 AH cells that are on sale, and has the word HOT in the drop down menu..What do you think Andy ??? Have you heard that before ??? I found a good deal on some cells that have never been used 280AH Catl cells that are definately HSEV for around the same price but are welded in series, 20S, which is OK, but I don't like welded cells, I will make a 48 volt16s and a 12 volt 4s out of the pack, by cutting one of the welded bus bars...Those Catl cells are fantastic, don't test over 300 AH though..Have a good night down under...
@@onthelake9554I could sell the welded together 12 volt 280 AH pack, which would bring the cost down, to like $1300, and since I live a few hours away, no crazy delivery fee, I'll pick them up..My buddy bought two packs, they are doing very good..But, there are some good deals out there for brand new cells right now, except my Bitcoin mining cash, has to last a long time, since I walked away from the rat race..
@@realeyesrealizereallies6828 Ok , as long as you consider that when you are deciding about their value . When I checked I could buy new grade a eve cells from an Atlanta company for very close to the same price and I could see them in person and pick them up with no shipping so that may have been why I didn't like them . Good luck !
The original EVE QR code says 280Ah. My 304 Ah cells all had correct QR codes too (and charged to an average of 312.5Ah, which is not as much as a difference, but great for grade B QSO cells).
Super Video, bin gespannt auf die Features von dem BMS, schade das wieder ein Dauerbalancer angeschossen wurde statt einen den man einstellen kann und schade das es das Gehäuse nicht einzeln zu kaufen gibt, aber vielleicht kommt das ja noch 😅. Aber der erste Eindruck sieht gut aus 👍
@@OffGridGarageAustralia das klingt doch gut. Ja gebe dir recht fürs Stapeln empfinde ich das von Seplos besser. Was mir aber beim GobelPower besser gefällt ist das mit dem Schalter und der Sicherung vorne drin, ich glaube ich warte da dann noch, aber vielen vielen dank für diese super Videos 😁
Great video. i'm currently waiting on custom battery boxes i designed up and currently getting made in china. very basic front, terminals and places for a Mini dc breaker and should be enough space for any bms (200mm area)
@@OffGridGarageAustralia Yep. their a battery factory who do their own batteries/packs with cases, etc. i talked to a person there and we did some designs and now currently in production of the cases. i just did 2 terminals and a mini breaker on the front. and hoping the 200mm space in front of the batteries will be enough for any bms. when i get pictures, etc i can email them to you.
@@OffGridGarageAustralia Gobelpower answered and provided the data to my battery: EVE LF280K Full capacity: 299 Ah Max charge V : 56,59V Min discharge V: 39.39V I‘m surprised about the very low discharge Voltage.
Andy, the basic model (even with 4A neeeeey balancer) brings according to gobel power website a voltage range of 49V - 54.5V. Is this correct ? What is your opinion about the basic model? Because I think you tested the premium model with eve cells... maybe gobel sent you a better version than the real basic model reflects...
I would not buy anything else than the basic version with the 4A NEEY balancer. Once top balanced, it will charge to whatever voltage you want, up to 58.4V, no problem. It is a bit confusing why they say it's not charging higher than 54.5V. They test all batteries unbalanced to make the batteries comparable. The basic model has just cells which are not as tight selected as cells for the other models. But the balancer will fix that, 100%.
@@OffGridGarageAustralia Shit, I read your answer to late and payed now already an upgrade fee of 430$ to get a standard version. However, with this I think (hope) I get also 5 years Limited Warranty also to the BMS, 1.2kWh more. capacity and 10kW power instead of 7.7kW. Was this worth the money?
Silicone Wire has a higher current rating than normal , imagine that . I tried to tell another UA-camr this and it didn't end well but he was hard headed and knew everything . It's the silicone insulation not the fine strand count that gives it the higher rating . The fine strand is only for flex . Others will argue , I will not .
The terminations of the cable are rarely rated for higher than 75-90C though so you can't use the higher temp ampacity that the silicon insulation is rated for.
Nice! It is a beast from the looks of it. I do question the temperature-range of your model though; How can it still operate at minus 30 degrees Celsius without a heater inside? BTW, I love those battery-connectors too, you should recognise them as they are the same as the ones that Müller Energy is using. ;-)
@@onthelake9554 Thanks! You are correct, it is indeed noted on their website that is the discharge temperature. I guess there was no space left on the label for the word "discharge" (haha). Still, with minus 40 degrees Celsius, I expect the capacity to be really dramatic? And for the on-readers, charge temperate is from 0 degrees to max 60 degrees, according to their website. Quite impressive, they give 10 years of warranty.
Which BMS integrates best with your Victron setup, Gobals PACE or Seplos v2? I'm looking to buy a DIY case, both apexium (seplos BMS with BT) and Gobals looks interesting and should work with Victron. Any thoughts on what the best DIY case is atm (for a victron system)?
Either BMS will work with Victron. The Seplos BMS will need some tweaking as shown in this video: ua-cam.com/video/xN60NkIEpno/v-deo.html In terms of the case, either the Seplos or the EEL box is great. off-grid-garage.com/diy-kits/
Seems weird that the DIY Kit is HALF the price of the other two. Are you sure it includes the EVE LF280K cells and the BMS ? For that price I could only buy the LF280K cells with JK BMS a few months ago ... Granted there will be probably still duties/VAT on top of that though.
Yes, all three variants include the cells, just not as well matched as in the other models. I wish they would have send me a DIY-Kit. Keen to look at these cells... But hey, for this price... cheaper than real DIY.
I think EVE was getting complaints about their 280ah cells not having 280ah so to make companies happy they made them 300ah and labeled them 280ah. Better to have more than not enough. Its a huge competition in China for these cells.
Yeah, OK, I can understand if they getting complaints about the capacity. I like the capacity under-promising of these cells. Test results in the next video...
Wires are gauge different for outside of case and inside of a case. Normally if they're inside the case there are rated One step higher. To be honest I don't like this I wish they were at the same everywhere. But it's a common practice for manufacturers if it's in a steel box.
@@OffGridGarageAustralia I don't think you understand what I'm saying. Most items with a wire in it are a gauge smaller. The manufacturer is not going to worry about it heat up 60 to 50 being that it's safe from you touching it. You will not get burnt. Now if you want to wire outside the case they want to go to the larger size wire so it does not heat up when you touch it.
Good if you can get it here in the US. Followed your link and attempted to get 3 units. I tried paying both thru bank transfer and credit card. after back and forth with both of them, the bank treated me like I am about to commit a crime, Credit card have decided not to approve the transaction due to "fraud suspicion" claiming they have their own internal review of the company and noted so many problems with previous transactions with the said company. (Mind you, this was almost a week of back and forth interaction with them including visiting the local bank branch with all proof of my identification they requested). Whether this is made up or real, bottom line I was not successful in procuring. Too bad. I guess I'll be stuck with what is available here. sigh...
OK, complete nonsense! Tried to order DIY kit. Kit itself costs £2106, but shipping £4626, and it says NO BATTERIES! So total £6765 (including discount code and payment fee) and that doesn’t include BATTERIES?!? WTF? (Shipping to sunny hot New Zealand :) )
Where are you seeing diy? I used the link on Andy's website, GP-SR1-PC200, discount to AU$4,056, (checked via phone without link, same discount), nothing on the page about diy?
@@Pippy626 Andy's vid must have run them out of stock. Thank you for replying. Andy, on the downlow between you & me b4 telling others about a bargain please😉
@@Lana_Warwick yeah he is getting a lot of heat in the forums over this battery because it’s not a deal. Once the video was out they hiked up the prices.
Hi Andy. Potverdorie ik wil ook zoon powerwall voor me huis. Als altijd, good information. Bedank. OK, I'm trying to bring back somewhat. I have learned in school. Yes, it's DUTCH. "What"
Why is there always something that ruins the "perfect" battery? Are you going to be able to convince them not to have the balancer on all the time? Why do they think the Neey balancer has ability to turn on/off to begin with?
The build quality looks fantastic! Unfortunately the 3AWG main cable is only good for approximately 100 amps! Not good to have that on a 250 amp breaker 🔥 😮
Update...I just saw the end of the video lol.. so that's like welding cable which would give more amp capacity... Being that short also helps. I still would not want a 250 amp main breaker personally. It's unrealistic to have that much current available on a battery pack anyway. At 200 amps and figure 50 volts for the battery, you would be pulling a 10 kilowatt load (which you could not do through the inverters) nor would I ever want to! 😂 Think of it as protection for your inverters. If you size your system properly and know the max your inverter should pull then you would want to size your overprotection for the battery lower than that so the load would disconnect. Failsafe in case you're inverters didn't shut down?
The main breaker acts more like a main switch to disconnect the system mechanically instead of just the soft-button for the BMS. If you really pull over 150A from such a battery for some time, I would consider a second battery. Otherwise it's not great system design.
You are doing some very important work to keep the manufacturers on their toes by testing their products to the limit!
Thank you for this great service to all people who are interested in solar power and storage.
Thank you for your feedback. I will definitely continue with that!
Mate they would fake everything, there are almost no new A batteries available for consumer to buy. All new batteries from manufacturer is sold in years in advance, everything else is repackage B/C and refurbished A from ev.
That information comes from people on the manufacturing sites in China and im impressed by naive approach of everyone just reading manufacturer specification and believe in it.
Hi Andy! Awesome that you do this test of the Gobelpower pack! I just finished my DIY build of the smaller version of this pack (150A Refinergy BMS). Gobelpower was so kind to sell me the metal case, BMS, etc separately so I could do an upgrade of my already existing 8S EVE280LF pack to a 16S pack.
The only modification I did was installing a NEEY 4A active balancer instead of the Heltec balancer. Support during ordering and even aftersales was great. The BMS I got had a problem by measureing on cell voltage and showed strange values. After contacting the support it was identified that the BMS was faulty and Gobelpower send me a new BMS free of charge which arrived after 6 days. Top service! Everything is working now and I‘m more than happy with my battery pack! 😊 Looking forward to your tests now and I‘m highly satisfied with the service Gobelpower has provided me! ( And no, I‘m not paid to write this, I‘m only a happy customer who paid all by myself)
Cheers Jens
Whilst one would praise the after sales service it would have been much better for them to send the correct working item in the first place. So now the idea rests vaguely in the back of the mind that these people were taking chances - hoping you wouldn't notice the faults and just install it and ruin your battery. That is how reputations are ruined - either by not testing products or deliberately taking chances, hoping to save money.
How much did they charge for the metal case if you don't mind me asking?
Thanks for sharing, Jens. That is great service. I think they were considering selling these cases separately for DIY projects. I have to chase this up. It's a great alternative to the Seplos Mason cases (but they come with the 10E BMS which is far less optimal than the Pace BMS).
I think it is great service of them to do troubleshooting with you and replace the faulty part so quickly. That's the service we need.
Great. Andy got the same battery I have got 5 months ago. Love it and many thanks for testing it. Got it with 40% SOC and nothing changes after month of no use.
Yeah, mine arrived with 37%. Jens had the predecessor on his channel a while back with a huge discount.
Do you have the active balancer already as well? I thought this is a fairly new feature.
Just got my Gobel Power Battery. It took about 2 months shipping from China to Germany. I used prepayment via wire transfer and everything went fine - you get a tracking number and can see the state f your shipment at any time. But GP seems to not use the Neeeeeeeeeeey anymore with the 4A Bluetooth option. I got a Heltec 4A Balancer. Bluetooth name is EK-24S4EB. I ordered the Basic option and it has 278 Ah at 42.31V - 56.64V during the GP tests. Delta V is 0.003 V at 40% SOC after arrival.
Seems like a great way to mitigate on customers complaining about battery degradation. Under promise and over deliver! Order 280Ah, get 300 Ah. :)
People will still complain.
@@mickwolf1077sad but sooooooo true.
Voltage sag is real in the first couple months of use, but they will level out around the 280 mark.
As you are in the last month of Winter we are in the last month of Summer. Days are getting shorter fast. Only have 50KW of battery but plenty of PV. Weather is in the 100 Degree range (37C) for the last week so AC units running full on. Due to short days the batteries go down to 30% every night. Looking foreword to some cooler weather next week. Keep up the great videos and thanks.
You can never have enough solar for your battery to keep it charged under all conditions. Do you have enough power in winter?
@OffGridGarageAustralia Think so. Have 18500 watts PV, so always get some solar, but we do have times when it is heavy clouds for a week. Nice auto start generator if needed.
I am more then excited for the second part of the testing. Thanks for your expertise Andy. Schöne Grüße aus Bayern
Yes, video is out now!
Oh, Andy, you know how to hook up your audience! Can’t wait your next video testing that beuty
Video is out now!
Best value level battery I've seen yet .
For US$2600 (-12%) it is probably cheaper then a DIY battery.
3AWG can handle the amperage required, depending on wire insulation type, run length, and constant load.
And 12% discount....I mean really, what else does one need!! Amazing product and thank you for the info on these.
I think the same. $2600 for the DIY-Kit -12%. That's very close or even under a DIY battery you can build yourself.
From my table for single conductor in free air for aircraft wiring, a 3awg wire @ 300Amps the temp rise is off the table which has a 100deg C upper end. I have extended the curve looks like some where around a 150deg temp rise above ambient.
Fuse and thermal runaway comes to mind. Copper has a 0.3% resistance increase per degC.
Danke Andy. cant wait on the results
Video is already out...
Thanks Andy 👍
Thanks, Wayne.
It’s came a long way in the last few years.
I can’t wait to see what is available in the next couple years.
When I bought these types were not available.
Hi Andy! Really, really interesting this Gobel Battery Pack!
-No welded cells!
- Good, perfect information and transparency, about the cells and the material, used for the pack! Really amazing !
- Gobel would then be the only ones manufacturer to have understood, what these potential customers want?
Well done !
In any case Thanks again Andy, and we are impatiently awaiting the test of the pack! 😁 Because It's true these Balancer all the time ON?? we will see ? Thanks to you Andy,😊
Yeah, they seem to have listened to the community. Also have a look at the second video about the capacity tests and the BMS settings. Really interesting.
I've been looking forward to this battery review. Following with interest.
Also, the next video with the capacity test. Really interesting.
@@OffGridGarageAustralia agree but want to understand how that active balancer is working. Your software said that active balancing started at 3.45V per cell but you are observing it sooner? Do you have current draw on the balancer cables?
Haha that angel sound when you noticed the 5A Balancer, cool.
BTW: the heated version is well known in Alaska.
It's the first production battery with a 5A active balancer, so our prayers have worked.
based on SOC your winter season is long gone . I had totally forgotten how many batteries you already have , but no clue about the capacity but I would guess about 90 kWh, so a day in your life without the grid and fully charging your Tesla - out of the battery.
Sooner or later you will become a neighborhood power supplier.
Next review point will be a grip test for battery wheels and a 40 lap test race between all your batteries on wheels.
I guess reviews will then take longer.
7:30 is a nice service about the built and configuration incl. brand and model of the cells plus quality. And of cause the capacity plus max Volt for your battery to check it.
But test done July 1st means that shipping to Australia might not have been so worse.
10:49 - I love this kind of communication what has been ordered and what it mean regarding quality.
Great progress I have to admit if they will deliver what they promise but gobel was also the company with the QR code transparency.
ANd if they will perform that way for a few weeks and tests I bet all others have fallen behind, lot behind.
But I still love the Frankenstein adventure a lot cause it is closer to us averages users that do not buy grade A.
I already generate all the power I need including hot water and EV charging. Crazy! This is all thanks to the large PV array on the garage and car port.
I have not connected any of these batteries to my battery shlef yet. The overall capacity would be around 2700Ah @ 51.2V. I will probably never connect them all to my system. Most are just here for testing, to learn explore and share.
Yeah, a few laps on a battery race track would be great😂
I also like the transparency Gobelpower shows in regards to these batteries. It is really great, that they step up the game and be at the forefront with such a system and database.
More Frankenstein videos coming...
It's more than clear that every (Chinese) company need a Andy Quality Controller 😉 You wonder why they don't watch and learn from his channel. Still no perfect battery available... Insane! 🐸
Yeah, all the info is out there. Many tests online. Someone just need to watch, take some notes and start building this perfect battery. It's not hard.
Yay, another video, faaabulous, great stuff- thanks Andy! 👍👍👍
You’ll soon have enough energy stored to go for weeks without sunshine 🌞
(This battery looks awesome!)
Yeah, nothing is connected to my battery shelf at the moment but I'm working on an upgrade now. Heaps more videos to come...
It's always so fun watching your videos thanks for the awesome shows keep up the good work
Thank you very much!
Gosh, i'd love to have one of those for my skoolie project.
The battery? Would a DIY battery not be more suitable so you can custom build the case to fit in the bus? I would assume you need at least two batteries?
I was thinking rack batteries under the rear bed would fit perfect...@@OffGridGarageAustralia
Hi Andy
Doesn't this active balancer have an enable/disable input. If it does have such an input you could manually start/stop the balancer.
It has such an input, yes. You can solder two cables to this and use an external switch for example. Or the voltage trigger as we have used in this video. It is then fully automatic.
ua-cam.com/video/kEeD-oM4QnY/v-deo.html
YOU ARE 💯 PERCENT CORRECT! The balancer should NOT be on all the time! You caught them, good catch.
We will test this out soon...
Andy i see they have a option for a 4A bluetooth balancer wonder if that option allows changes in the active balancer voltages?
Yes, that's the NEEEEEEY active balancer you can opt in for. All settings can be adjusted then.
Hey Andy, I was just reading some news, and it looks like a company making LiFePO4 battery packs for cars has come very close to achieving energy density parity with traditional lithium ion battery packs made using 18650 or 21700 cells. I really hope this new technology ends up shrinking the size and weight of the current LiFePO4 cells on the market now, or maybe you will be able to get 400Ah into something the size of a LF280k. I also saw the 1st factory being built that is supposed to start producing solid state batteries as well. Those should have fairly big improvements over all of the different lithium chemistries we have now. I'm Excited to see what the solid state cells can do, and if they will have any big flaws, like being really fragile because of the porous ceramics they were using as a solid electrolyte. Let us know if you find any big news like this in the future! I'd love to see LiFePO4 with a new electrolyte or some anode and cathode improvements.
Yeah, all these news around new battery tech. Only 0.001% will make it into production. I have stopped reading that stuff. It's all theoretical and test in laboratories. As soon as there is no facility with serious production lines, the tech you read about will most likely not come to market.
Solid state... that's a good example. Promised for the last 10 years and still not here. LiFePO4 is great and will be around for a long time. I have now some Na+ cells here to test, but tech is not there yet and no serious production lines. This may come though over time for this technology.
There are multiple variables that determine the ampacity of any given conductor besides cross sectional area and the material from which it is made. Obviously insulation temperature rating, but also ambient temperature, free air vs inside a raceway, single or multiple conductors, and temperature ratings of the devices to which the conductor connects. But, for the sake of making the battery more efficient, I'd sure like to see heavier cables.
Yes, correct, the installation method is important too. We're just checking roughly here if the cable is the right size.
Chinese batteries always save on copper. They could have just added a third 7AWG wire for $2, would have sufficient cross section for the breaker and nobody would even question it.
However, I'm not expecting anyone pulling more than 50A from such a battery for an extended period of time. That would be bad system design.
At 14:40 you cut off the white cable sheath. What is it for? Is the red resp. black cable sheath not enough for isolation?
What is included in the delivery? Handbook is a bit confusing. Handbook chapter 3 "Scope of Delivery" states
- battery,
- wall mount,
- 2x 1m battery cables and screws,
- 1x inverter cable D1 and
- 1x PC-RS232-USB cable D2.
Later it stays "not included" D1, D2.
All the cables are included, so also D1 und D2
Thx
@@prof.mobilux thank you, I hope I will not have to wait 2 more months for these :D
Sounds like someone getting a split AC for the garage with all that power why not keep up the good work mate
Last days of winter. I'm behind my schedule so need to hurry up before the big heat is coming back...
Maybe these are LF280K V3 cells. Those cell terminals (oct-shape?) do not match the LF280K V2 cells we got so far. Also SunFunKits states they test between 290 and 315 Ah - but they use their own terminals/studs which they weld themselves.
Yes these are the new LF280K V3 cells with octagonal terminals. With my last order from Gobel (just cells only) I got them too. I'm still testing the capacity...6 cells are done: 305-307Ah with EBC A40L 3.65V->2.5V 30A.
Wow, nice test results. I've done mine too and share it in the next video.
V3, ey....?!
Hi. That 3 AWG wire can handle more than 200 A. The bms is rated for 200 A. Si you can't charge or discharge with more than 200 A right ?
The BMS can handle 200A in both directions. I would not recommend it to protect the batteries. If you have such high currents, get a second battery in parallel.
6.30 is a choral track by Libera! Think its Vespera but could be wrong! Here for the battery’s but been a fan of `Libera since the 90’s when they where called St Philips! Battery and choral geek out in one video! 😂❤
Are there any concerns left where you would say, do not buy yet and wait for my next video or xyz test ?
I can remember that you were not so happy a about a cable which consisted out of 3000 tiny single wires where they said they wanna test it with a 300 A current.
But anything else worth to wait for ?
I will do a few more tests with the battery. Maybe if this in your consideration, wait for the results to get all the info.
Whilst their attention to detail is impressive, I must admit that at these prices, I feel it's almost equal to a big-name brand solution. You can get an LG LGES-5048 + LG RESU 12 LV bundle for ~10k AUD. The LGES-5048 is effectively a rebadged GoodWe with greater capacity, and a really nice hybrid inverter, worth 2k+ alone.
I think the Gobel DIY-Kit battery model is very attractive in price and comes close or is even under a DIY build you do yourself.
@@OffGridGarageAustralia I've been trying to save enough $$, to get a few good panels and some decent size batteries for MT year round job as an
equipmentwatch/firewatch . for some reason, these last 3yrs, I haven't been able to save any $$. It must be the price of toilet paper and having to deal with so much 💩💩💩💩💩, here in the US...
I've been using 2, now 5, lead acid deep cycle batteries, with a little 400W invertor & 80W panel.
The invertor shuts off at around 11v, which has likely kept my batteries from dying too quick.
I was running a basic 3500w generator, which ran 11hrs on 4 gallons of gasoline. I was lucky enough to get a 2000w generator that goes 12 hours on 1.2 gallons at low load and it goes 8hrs on full load
It has helped cut fuel costs down, but,,, a few good panels and better batteries, plus a better invertor would probably pay for itself by not burning expensive fuel.
I don't buy ice anymore as I have a small chest freezer and freeze bottles of water, for the cooler, to keep food cold.
I have a 5kw AC unit, to keep me and my almost 4yr old RottnLab cool, during hot weather.
It would be nice to be able to operate the chest freezer and AC unit running on solar/battery power, just using the generator occasionally, to keep batteries charged.😎☕
Isn't the Gobelpower 3 times the size?
@@andrewflies9119 No? The LG RESU 12 LV is 13.1kwh. This Gobelpower is 14.3kwh.
Very well put battery but not to be used in powerwall mode, I don't like when the cells are not upright, concerns me that electrolyte won't be in bottom of the cell. Andy what is your opinion on that?
It is not a problem at all. The cells are fully compressed and there is no air in these cells, so the electrolyte wont settle on one site. As per manufacturer specifications, these cells can be used in any orientation except upside down.
If they are not upright (terminals pointing up), I would highly recommend compressing them though.
Andy how much Battery Capacity do you have now in service ? 110 KW/h ? Are you going to build a "new" Battery Garage ? When will you test Natrium-Ion Batterie Cells any hope ?
Still running the 44kWh in the battery shelf. None of the other batteries is actually connected right now. All for testing purposes only.
I'm working on more storage though as well as on more solar... 😉
This looks like a very good design to me. Do they have anything smaller? If I were to install home batteries, they would need to go up some stairs. Or maybe some really long DC cables from the planned hybrid inverter upstairs, but that's going to be a challenge as well. Someting modular in luggable parts of 25 kg or less would be better. Or maybe something with a hot swap bracket system, so you can add or replace individual cells as needed, just like computer data storage systems. Minimum combined voltage and matching capacity may be an issue there, but just ordering a new replacement cell module is much better for the environment compared to replacing (and transporting) the whole system.
Yeah, the weight is really a problem with these batteries. Hence other manufacturers are going in 100Ah modules at 50kg.
@@OffGridGarageAustralia Maybe you can ask them for a modular version? They seem to be listening to your other suggestions, and scaling down such a design should not be too hard for them, judging from the excellent quality. Something small and stackable would be great for the people without a garage that doubles as a power plant 😂
Just having a think on the balancer being a little too active
I do wonder if there is a way to use the DCT to turn on the balancer, I'm sure the trigger will be easy to work out, but on the balancer side...? I'm sure it wouldn't be too hard for you to DIY a way to fix this over active balance issue
side note, one of my jk bms reads the voltage 0.2 volt higher than the rest and Ive learnt today what issues that can do with trying to balance on the flat part of the voltage, I know I can change it, but for now I want to see exactly what it will do long term
Not hard to do at all with the voltage detection controller as shown here: ua-cam.com/video/kEeD-oM4QnY/v-deo.html
Yeah, these long term tests. I have many of them running 😂
Thank you for this very nice job you do with all these videos.
Can you tell more about these BMS dry contacts. What can we do with it ?
Thanks again !
I had my windows PC apply a windows update in the middle of a test and reboot, was that what could have happened to you ?
The same thing i thought too...
First thing I turn off is the auto reboot or reboot at night. All other programs like browser and file explorer were still open.
It was a stuck Win update though, which I didn't bother fixing.
I really like when a manufacturer includes a circuit breaker and not just a fuse. It'd be nicer if they'd put the fuse in an easier to access location given it has a lower current rating than the circuit breaker, but otherwise the hardware looks really well put together
The battery is rock solid built. I'm really happy with what they have put together.
Hopefully, you will never have to replace the fuse in this battery. I think it is fairly accessible once the front panel is removed. Also with a ratchet extension, the nuts can be removed from the top.
@@OffGridGarageAustralia It really looks like a great battery, watched the follow up with the charge and discharge tests and it looks really well put together with high quality cells
I guess the breaker probably functions more like an isolator, since the fuse would pop long before it does
One other minor niggle, I find the soft reset button on the BMS annoying. I'd much prefer a rocker switch or something to disconnect the BMS power supply
When I switch something off, I want it to be OFF 😁
Hi Andy.
Thier DIY kit with your code is a good value kit of bits, not much more than I have spent so far sourcing all my own components. 😂😭😭......
Not including the shipping to me in Scotland though.
FOGSTAR UK Can't be beaten for that!
As always love from 🏴
Gaz
Yep, I think this will be a great battery!
Excellent seen the CE label nice I love seeing these new setup but like to see more Aussie built batteries but they should watch your channel we will get there lol still I like to see a cell in a fire and a starpicket pierce test hahaha(I know the result you be surprised their safer than you think)
I'm not aware that anyone in AUS is building such 48V batteries. They all import from China anyway afaik.
Would be good though if we could get them locally.
I just went to lithium batteries “260ah x 2” I accidentally shorted one out hooking them up. I charged them up at the same voltage. The battery shorted did shut down, :-) it had to be woke up. This batter is the head battery in my parallel system. After a few days of use this batter is at a lower % than the other battery. The voltage is holding even on both batteries. Do you think I might of hurt the shorted out battery?
Charge them both up to 55.2V and they will balance out again. If the short was only for a split second, there is no harm.
You have to be more careful when working with these batteries. Always take a cloth and cover all the surrounding terminals so this cannot happen.
@@OffGridGarageAustralia Ya I was careless “the BMS seemed to instantly shut off” think you so much for your reply I’ve been freaking out do to just buying these batteries 🫨. I think it was you that said you can’t get a mid point %. On parallel wired batteries 🤔. It was showing 99.80% deviation 🥴. So I turned it off on my victron battery monitor. So I would quick worrying about it.
What is the recommended Grid Amp setting for this battery? I see in the video says max 140A in the specifications sticker but what would be the recommended setting? Thank you
Heya, that are some good cell's I believe 297Ah wouw nice. I received my 16 lfp4 cell's they clame 320Ah but the first 2 battey cell's have 297 and 293Ah (tested with the the EBC-A20 tester) so I gues they are 280Ah cell's. still testing the other 14 cell's as we speak will upload a vlog about the testing.
How about the breaker, can it handle the short circuit current of 21,3kA from the batteries without arching?
This battery box looks very interesting. I actually only miss the version without batteries. Is there such a thing? Or another brand that uses the PACE BMS.
Amazing you got this from lift to hand truck to on the floor. Done ✅
? Wire ? Dates ? I see why you look 👀 look but verify 😂
Hi Andy, I am really keen on seeing your findings about the batts that I own for 1 month now..
So far my impressions are identical to yours: Good quality!
Have you got the Gobelpower battery as well? Which one did you get?
I am a Fan of your work :) how it the progress in balancing the Seplos battery? my Frankie battery getting progress in top balance but still have 3 cells rushing back to under 3.37 when charging current drop under 4 amps.
Thank you!.
Yes, the Seplos battery is still cycling every day. Results will come soon.
you cannot access the battery terminals to charge individual cells?.@@OffGridGarageAustralia
Can you get this pace bms to communicate with the Jaki's pace bms?
Yes, it's the same BMS. I have shown this a few times in videos.
Nope, the Seplos V3 will not balance over time...but it would work with the 10C or 10E BMS.
My Gooble Power 280Ah Pack has still the RN150 Refinergy BMS...it does not balance well...but seems like they resently upgraded that to Pace entirely.
I am curious to eventually test the Pace BMS myself...maybe we can adust the settings in a way, that they don't even need the active balancer anymore...
You can still get the GP BMS with 150A. All new batteries have now the 200A Pace. Both BMS are very good.
In this point, I have to disagree with you...they are both switching off the charging MOSFETs, once it resets to 100% SOC. So you first have to discharge the battery (to 96% I think) to be able to charge it back up.@@OffGridGarageAustralia
My limited understanding is that these types of silicone high amp cables rely on being able to heat up safely while delivering the stated amps. Please correct me if I am wrong. If this is true, then the cables will be hot and we want to remove any extra heat in the system. Increased heat equals increased resistance, again limited understanding and happy to be corrected. We want the system to run cool even if under load continuously for the full capacity of the battery. I want to apply the same thinking to those busbars which seem under specifications for an environment with no airflow. I hope someone out there in the community with more knowledge can reply and shed some more light on this subject here.
Andy, the *Cable* (insulation) might be able to withstand high temperatures and therefore operate up to 240 ARMS. BUT what is connected to the cable & cable lugs is typically only rated 60-75°C (in some cases 90°C). You typically see this indicated on Switch Disconnectors, Breakers, etc. "Use only 60-75°C Cu (Copper)". You don't want your hot cable heating up what it is connected to (Breaker, Cells, ...). Actually the cable should be a thermal sink pulling the heat away from the breaker, NOT the other way around.
Yeah, good points. I don't know if people really pull close to 200A for an extended period of time from such a battery. I think this is bad system design and these guys need a second battery in parallel.
Really enjoy the humor in your videos Andy. Nice to see Gobal using the new style 280AH cells with the hexagon terminals. They seem to test so much better in Ah then the older 280Ah cells. With that said, fu*k B cells lol. I can't imagine using a B cell for my customers. This sort of BS is why I build the batteries for my customers.
Side note regarding the end of the video, I stand by my statement from over a year ago, an active balancer is only necessary when you first build a battery to speed up balancing. You do not need it after that.
Well, we will test this now with this battery, does it need an active balancer at all?
How many battery life charge cycles and how much is it
See the video description.
Hallo Andy mich wundert das dein Pack keine 2te Sichereung hat. Bei mir sitzt sie genau nach 8 Zellen eine Sicherung als Brücke zwischen den 2 Batterien Reihen. Meine batterien sind von Jan/2023!?
That is the 'older' design battery. The SR1-PC200 has one fuse and a breaker in line with the positive.
Your pack has also the 150A Gobelpower BMS, I assume.
Superklasse Video sehr schöner Speicher. Vielen Dank👍🏽😉🍀
Andy, I just pulled the trigger on the Gobel "standard" pack. The rest of my system is old school but operating just fine. Outback charge controller and AIMS 48v inverter without a comm port. Will the Gobel operate just fine or is there anything additional I need for monitoring? Ex. Victron BMV-712. Thanks in advance, PROST! Scott in Las Vegas, NV
I went to their webpage and did not see any 24V model. Are you aware of any 24V preassembled or kits from them?
No, not aware that they have 24V batteries. Only the usual 12V batteries for 4WD and RVs and the home storage.
@@OffGridGarageAustralia thank you
This is awesome. Dem i want this one. But i don't need it yet.
Maybe your computer forced a nightly reboot after an automatic update?
Nah, all the other programs were still running (web browser and file explorer). There was a Win update stuck for weeks and I didn't bother fixing it. I did now and it seems to have solved the issue. Auto restarts are turned off in all my systems.
Ok, so i now want this enclosure, same batteries, 250A charge and discharge bms, 75mm wires, screw terminals and my own neeeeey 4A programmable balancer 😂 Can it be done?!
Get a quote 😉
This actually seems like a good price for these (with the discount before shipping) Now if I can only convince the wife.... lol I'm looking forward to the full test. I wonder how much worse the "DIY" kit is vs the "A" Too bad they didn't send you a DIY one as well.. But my guess is they cherry picked a unit that had above average cells for you to review!
Yeah, I wish they would have send me a DIY battery. I would not worry about it and take the DIY Kit they offer. With the active balancer in place, it will sort itself out. It's in the next video... and for US$2600, it's a bargain!
Gobel power HSEV 280 AH cells are on sale, and are a pretty good deal...When you read the description, it explains the "B" on your cells, they say that they are ESS cells, but to test that good, it's confusing..Apparantly EVE now prints a "B" on ESS cells so that they cannot be sold as HSEV cells...Because they cannot be distinguished from each other, in any other way, other than the paperwork which could be forged..That is what it explains on their website when you click on the raw EVE 280 AH cells that are on sale, and has the word HOT in the drop down menu..What do you think Andy ??? Have you heard that before ??? I found a good deal on some cells that have never been used 280AH Catl cells that are definately HSEV for around the same price but are welded in series, 20S, which is OK, but I don't like welded cells, I will make a 48 volt16s and a 12 volt 4s out of the pack, by cutting one of the welded bus bars...Those Catl cells are fantastic, don't test over 300 AH though..Have a good night down under...
Find out how many years old those CATL cells are and consider that before you purchase . I think I know which you are referring to .
@@onthelake9554 Ya, they are the ones you are thinking of, they are 2 years old...They do come with the paper work and test good..
@@onthelake9554I could sell the welded together 12 volt 280 AH pack, which would bring the cost down, to like $1300, and since I live a few hours away, no crazy delivery fee, I'll pick them up..My buddy bought two packs, they are doing very good..But, there are some good deals out there for brand new cells right now, except my Bitcoin mining cash, has to last a long time, since I walked away from the rat race..
@@realeyesrealizereallies6828 Ok , as long as you consider that when you are deciding about their value . When I checked I could buy new grade a eve cells from an Atlanta company for very close to the same price and I could see them in person and pick them up with no shipping so that may have been why I didn't like them . Good luck !
@@onthelake9554 Well. the price is much lower than on the website if you pay cash, and pick them up. Almost 30% lower, but, I'm not 100% sure yet..
Amazing ❤
its gotta be 304AH cells derated? right??
I mean, it should not be able to have that much capacity if designed properly.... The stories of EVE cells continues...
The original EVE QR code says 280Ah. My 304 Ah cells all had correct QR codes too (and charged to an average of 312.5Ah, which is not as much as a difference, but great for grade B QSO cells).
They couldn't be relabeled at EVE?@@davidpenfold
If that is the case tho, i'm excited to get some!@@davidpenfold
Yeah, not sure how these batteries are rated and have a genuine EVE QR code with a 'B' at the same time.
Super Video, bin gespannt auf die Features von dem BMS, schade das wieder ein Dauerbalancer angeschossen wurde statt einen den man einstellen kann und schade das es das Gehäuse nicht einzeln zu kaufen gibt, aber vielleicht kommt das ja noch 😅. Aber der erste Eindruck sieht gut aus 👍
They may offer the case just by itself with some accessories in the future. Just like the Seplos Mason. Which is great btw!
@@OffGridGarageAustralia das klingt doch gut. Ja gebe dir recht fürs Stapeln empfinde ich das von Seplos besser. Was mir aber beim GobelPower besser gefällt ist das mit dem Schalter und der Sicherung vorne drin, ich glaube ich warte da dann noch, aber vielen vielen dank für diese super Videos 😁
Great video. i'm currently waiting on custom battery boxes i designed up and currently getting made in china. very basic front, terminals and places for a Mini dc breaker and should be enough space for any bms (200mm area)
Oh, wow. You let them build in China and ship to you? Interesting...
@@OffGridGarageAustralia Yep. their a battery factory who do their own batteries/packs with cases, etc. i talked to a person there and we did some designs and now currently in production of the cases. i just did 2 terminals and a mini breaker on the front. and hoping the 200mm space in front of the batteries will be enough for any bms. when i get pictures, etc i can email them to you.
The QR-Code on my battery is not working 😢
On your Gobel Battery? contact them, they haven't added the data to their website yet. Mine was the same at the beginning.
@@OffGridGarageAustralia
Yes, on my Gobel battery.
I‘m going to contact them and ask for it.
@@OffGridGarageAustralia
Gobelpower answered and provided the data to my battery:
EVE LF280K
Full capacity: 299 Ah
Max charge V : 56,59V
Min discharge V: 39.39V
I‘m surprised about the very low discharge Voltage.
COULD YOU INPLUG THE ACTIVE BALANCER AND RUN THE BATTERY?
It's in the next video...
Hi! I want to order EVE 280 cells from GobelPower. Do they sell reliable cells? Thank you
Andy, the basic model (even with 4A neeeeey balancer) brings according to gobel power website a voltage range of 49V - 54.5V. Is this correct ? What is your opinion about the basic model? Because I think you tested the premium model with eve cells... maybe gobel sent you a better version than the real basic model reflects...
I would not buy anything else than the basic version with the 4A NEEY balancer. Once top balanced, it will charge to whatever voltage you want, up to 58.4V, no problem.
It is a bit confusing why they say it's not charging higher than 54.5V. They test all batteries unbalanced to make the batteries comparable. The basic model has just cells which are not as tight selected as cells for the other models. But the balancer will fix that, 100%.
@@OffGridGarageAustralia Shit, I read your answer to late and payed now already an upgrade fee of 430$ to get a standard version. However, with this I think (hope) I get also 5 years Limited Warranty also to the BMS, 1.2kWh more. capacity and 10kW power instead of 7.7kW. Was this worth the money?
Silicone Wire has a higher current rating than normal , imagine that . I tried to tell another UA-camr this and it didn't end well but he was hard headed and knew everything . It's the silicone insulation not the fine strand count that gives it the higher rating . The fine strand is only for flex . Others will argue , I will not .
It’s not every silicon cable. The ultra flexible cables have very thin strands, and these strands are responsible of conducting the extra current.
@@gfjardim1983 See above comment .
The terminations of the cable are rarely rated for higher than 75-90C though so you can't use the higher temp ampacity that the silicon insulation is rated for.
Nice!
It is a beast from the looks of it.
I do question the temperature-range of your model though;
How can it still operate at minus 30 degrees Celsius without a heater inside?
BTW, I love those battery-connectors too, you should recognise them as they are the same as the ones that Müller Energy is using. ;-)
Discharge to -30 but not charge .
@@onthelake9554 Thanks! You are correct, it is indeed noted on their website that is the discharge temperature. I guess there was no space left on the label for the word "discharge" (haha).
Still, with minus 40 degrees Celsius, I expect the capacity to be really dramatic?
And for the on-readers, charge temperate is from 0 degrees to max 60 degrees, according to their website.
Quite impressive, they give 10 years of warranty.
Which BMS integrates best with your Victron setup, Gobals PACE or Seplos v2?
I'm looking to buy a DIY case, both apexium (seplos BMS with BT) and Gobals looks interesting and should work with Victron.
Any thoughts on what the best DIY case is atm (for a victron system)?
Either BMS will work with Victron. The Seplos BMS will need some tweaking as shown in this video: ua-cam.com/video/xN60NkIEpno/v-deo.html
In terms of the case, either the Seplos or the EEL box is great.

My jk took 1.5 months to balance by pack with 300ma 😅
But it did it! 💪
Shipping for one of this batteris to Norway cost over 3000EUR. It seams very high to me.
Seems weird that the DIY Kit is HALF the price of the other two. Are you sure it includes the EVE LF280K cells and the BMS ? For that price I could only buy the LF280K cells with JK BMS a few months ago ... Granted there will be probably still duties/VAT on top of that though.
Yes, all three variants include the cells, just not as well matched as in the other models. I wish they would have send me a DIY-Kit. Keen to look at these cells... But hey, for this price... cheaper than real DIY.
Wait, it says it is $2600 USD for the DIY Kit with no cells included??? Hopefully Andy explains why so much by the time I finish the video.

It looks like they are included to me , it gives a grade for them .
@@onthelake9554 Okay.. that is more reasonable.. It's always a bit confusing seeing what exactly you get on a lot of these listings.
Yes, all three models have cells included.
Awesome! Courier has emphasis on the "cour" otherwise it sounds like "career" or "korean"
My German is much better.
I think EVE was getting complaints about their 280ah cells not having 280ah so to make companies happy they made them 300ah and labeled them 280ah. Better to have more than not enough. Its a huge competition in China for these cells.
Yeah, OK, I can understand if they getting complaints about the capacity. I like the capacity under-promising of these cells. Test results in the next video...
Today you can order the battery including free shipping to Germany, tax, 4.4% bank transfer for about ~3,000 EUR.
Wires are gauge different for outside of case and inside of a case. Normally if they're inside the case there are rated One step higher. To be honest I don't like this I wish they were at the same everywhere. But it's a common practice for manufacturers if it's in a steel box.
It is up to you to choose the right wires to connect to the battery. Depending on the expected current, I would choose 50-70mm2 for such a battery.
@@OffGridGarageAustralia I don't think you understand what I'm saying. Most items with a wire in it are a gauge smaller. The manufacturer is not going to worry about it heat up 60 to 50 being that it's safe from you touching it. You will not get burnt. Now if you want to wire outside the case they want to go to the larger size wire so it does not heat up when you touch it.
Good if you can get it here in the US.
Followed your link and attempted to get 3 units. I tried paying both thru bank transfer and credit card. after back and forth with both of them, the bank treated me like I am about to commit a crime, Credit card have decided not to approve the transaction due to "fraud suspicion" claiming they have their own internal review of the company and noted so many problems with previous transactions with the said company. (Mind you, this was almost a week of back and forth interaction with them including visiting the local bank branch with all proof of my identification they requested). Whether this is made up or real, bottom line I was not successful in procuring. Too bad. I guess I'll be stuck with what is available here. sigh...
OK, complete nonsense! Tried to order DIY kit. Kit itself costs £2106, but shipping £4626, and it says NO BATTERIES! So total £6765 (including discount code and payment fee) and that doesn’t include BATTERIES?!? WTF? (Shipping to sunny hot New Zealand :) )
Hahaha, what a bargain! The GP-DIY-Kit comes with batteries though.
The diy kit is only 450$ more then the batteries alone crazy
And you get the Pace BMS, balancer, metal case, cables, connectors and all accessories. Very hard to beat.
Where are you seeing diy? I used the link on Andy's website, GP-SR1-PC200, discount to AU$4,056, (checked via phone without link, same discount), nothing on the page about diy?
@@Lana_Warwick 3 weeks ago on the site they had a DIY option that seems to be missing now. It was a savings vs assembled packs.
@@Pippy626 Andy's vid must have run them out of stock. Thank you for replying.
Andy, on the downlow between you & me b4 telling others about a bargain please😉
@@Lana_Warwick yeah he is getting a lot of heat in the forums over this battery because it’s not a deal. Once the video was out they hiked up the prices.
The cherry 🍒 picker!
Hi Andy.
Potverdorie ik wil ook zoon powerwall voor me huis.
Als altijd, good information.
Bedank.
OK, I'm trying to bring back somewhat. I have learned in school.
Yes, it's DUTCH.
"What"
Failed 304 AH cells maybe?
And a fake QR code?
Top gear alternative 😂
Like# 2
🍀 fourth 😉
Why is there always something that ruins the "perfect" battery? Are you going to be able to convince them not to have the balancer on all the time? Why do they think the Neey balancer has ability to turn on/off to begin with?
They offer a NEEY active balancer for $60 surcharge. I think, this is a great option.
I'm willing to bet 90% of all these server rack batts have Grade B cells on them.
Especially the ones that say they do like this one .
I would probably say close to 100% of these batteries have storage grade batteries in them.
The build quality looks fantastic! Unfortunately the 3AWG main cable is only good for approximately 100 amps!
Not good to have that on a 250 amp breaker 🔥 😮
Update...I just saw the end of the video lol.. so that's like welding cable which would give more amp capacity...
Being that short also helps. I still would not want a 250 amp main breaker personally.
It's unrealistic to have that much current available on a battery pack anyway.
At 200 amps and figure 50 volts for the battery, you would be pulling a 10 kilowatt load (which you could not do through the inverters) nor would I ever want to! 😂
Think of it as protection for your inverters. If you size your system properly and know the max your inverter should pull then you would want to size your overprotection for the battery lower than that so the load would disconnect. Failsafe in case you're inverters didn't shut down?
The main breaker acts more like a main switch to disconnect the system mechanically instead of just the soft-button for the BMS.
If you really pull over 150A from such a battery for some time, I would consider a second battery. Otherwise it's not great system design.
I mean, if you really pull 150A for some time on a regular base, a second battery would be the better system design anyway.
