Gobelpower HSEV Cells in Seplos MASON DIY Box. What a result!
Вставка
- Опубліковано 17 лют 2024
- And here we are testing the #Seplos MASON Vertical DIY Kit equipped with the #Gobelpower HSEV cells. We have a look at the Seplos BMS 10E in parallel with two other Seplos BMS, what info the mobile app shows, how consistent the Gobelpower cells charge. I also show how to fully top balance a battery in 30min with the help of a good old friend: the NEEY active balancer.
We finally start the capacity #test but need to interrupt because a hotspot occurred near cell 16. The problem was quickly located and fixed. The end result of the capacity test is fantastic, so the Gobelpower cells work well in the Seplos DIY case.
Finally, I'm doing a test to trigger the current limiter in the Seplos BMS. I really like and hate this BMS!

Thanks a lot for this great comment. That's a lot of encouragement to keep going. I'll be going back to the garage right now and make another video. For you and everyone else.
Hi Andy, one option is to just disable total pack overvoltage protection. And rely on cell high voltage protection and total charging high voltage protection.
That way it should reset to 100% without turning of the charge mosfets.
very nice tests, as always, Andy. Thank you very much!
My pleasure!
Thanks for all your work Andy.
I bought Gobel battery box with bms and put my cells into it.
I also bought another rack battery from them. Now I have 29 KWh storage.
Took me a long while to get the rs485 talking to my powmr inverter but that’s working now!

Heya, nice test video and so goood to see those gobel cell's are that good and congrat's at 80K sub
Thanks a lot being part of this great community🥳
Thank you Andy you inspired me to buy more batteries 🔋 😀 😅. Upgrading to 50kwh plus club.
Oh, don't! I really don't want to, but it is so addicting😄
@OffGridGarageAustralia I have high load in the summer ☀️ more than 6kw in the night sometimes! So if the utility turns off more than 4 hours I may stay in the dark 😅.

Thank you very much, Max!
Beautiful tests!
Thank you!
I have 4 of the 10E BMS in parallel in my system and they have no problem hitting 100% SoC all the time without hitting OVP. They are sitting at 100% right now in fact in the early afternoon.
Great for you. Please share how to do it.
The info from my BMS comparison sheet does not work reliably.
Congratulations on 80k Andy. ☺️
Oh, yes, thank you. Time to print some new signs...

Thank you. I love making them!
Great test result from Gobel battery supplier.
Yes, I'm very happy with these batteries!
lol when that 150amp was flowing, scary ! hehe
Yeah, that was all going through that 63A DC breaker. But not long enough to drip it.
80 K subs - congratulations
6:35 - SEPLOS BMS 10E V16.6 is used in the rack and the Mason Power Tower as I call it (even though it is really rather an Energy Tower than a power tower) ?
And that is the V2 and not the V3 ?
I don't understand why they have 2 different BMS for the black rack cases and a different one for the Power Tower.
But you had also said in the previous video that you had ordered the power tower with a different bms that would match your previous Mason.
Therefore I am now struggling what should be in that Power Tower usually and what is in your specific one or is it a general one without changes.
I am watching this video for the second time and I am still unsure. But great video and great success getting close to 100k !
All they deliver now comes with their new V3.0 BMS unless you specifically ask for the 10E BMS (which I did back then).
You're really making me confident I can build my own battery packs some day, I can't wait
I'm eyeing some 25ah cells to build a 16s electric bike battery, the acceleration should be crazy because they're rated at 3c continuous.
That's a peak sustained discharge of almost 4 kilowatts, if I ever needed that much
Your controller will limit the current to the motor. So acceleration will be the same, just more distance.
Just now putting together 2 - Seplos 280 DIY horizontal kits... a little lack of QC me thinks. Push buttons for active balance missing, Busbars don't line up with the screw-down points, and then jumping thru hoops for them to make it right............
Andy, great video it has helped me to get my batteries to 100%.
I am in the UK and running the Seplos with a multiplus 2 and a grid tied inverter. I don’t have anything to discharge the batteries other than through ESS in the Victron, will I be able to achieve the full discharge this way? I have the new V3 BMS with active balancing.
Thanks Merv
Thanks Merv. If you can discharge the battery by exporting the energy to the grid through your ESS, that will do the trick. Is that what you meant?
The calibration of the BMS is actually not too important. It will learn over time, and you can always manually overwrite the setting anyway.
Does the BMS need to trip out on under voltage to set the 0%?
The settings in the ESS won’t go low enough to trip. I have ordered a 48v inverter so that I can load it up like you did, hopefully that should do it.
hey andy ,, did you have a look at the gui v2 ? its cool especially for remote displays in your home
No, I haven't had a closer look at it yet. Seen some screenshots... very different.
Love from India ❤
Hello to India!
andy, I have big problems with gobelpower. That would actually be material for its own video! 🙈They don't want to come any way towards me with my 4 peaking cells! They're all seriously trying to convince me that over 100mV deviation would be normal at 55.2v! As I have now found out, I have LSEV cells that gobelpower now treats as GradeB cells. But I'm sure I didn't buy any B cells! I need your advice! please!
What’s the ‘secondary tripping protection’ warning?
Thanks Andy
Thank you, Wayne.
A monster bank ;) How many Ah? 1000?
As usual, it's very good. I was wondering if anybody (individual) else in Australia has as much batteries and solar panels as your capacity.? It's a very large investment of money and time. Keep them coming Andy.
Other mod their cars and go on race strips from time to time. Cost them 10.000s of Dollars. Playing golf is not cheap wither. We used to scube dive back in Germany, the gear cost a fortune...
Just found a new hobby, I guess...🤷♂️
@OffGridGarageAustralia I wasn't critical of how much money was invested. I was more thinking of others who have done the same and perhaps shared information. The reason is finding out how worthwhile it is and to encourage others to do the same. I think it provides a great deal of enthusiasm, which is so needed with current environmental effects. Keep spreading the word, Andy.
@@teapot_ Thank you. It is just if I tell what I have spent, many people may be put off doing their own projects as they think it is too expensive. I'm buying a lot more equipment and batteries than I actually need just for testing purposes.
It is more beneficial, if people understand the topic better and know what to buy for their own needs. My project and design certainly does not fit everyone else, so neither do the costs
😎
Hello my friend🙋♂️
has anyone done a video on how to choose the bms for your system cant seem to find one anywhere i have 24v system 5000w solar panels in total which has 8pcs of 320Ah lithium iron phosphate battery pack, A-grade, 3.2V Solar panels 250w ea x 20 pannelsand a Mr power 4500w hyrid inverter t i was told i need a 400amp BMS thank you keep up the great work andy
There is no clear answer to that. You have to choose the BMS as per your needs. How big is your battery, how much charge current, what is your load and max discharge current, cabling, breakers... all this.
- 5000W at 24V makes 208A for your solar (far too much for your battery to charge with for my taste). A 200ABMS is just enough here if you can limit your MPPTs to 180A.
- 4500W at 24V makes 187A (too much for your batteries, I would say). A 200A BMS is fine.
I would not recommend charging/discharging these batteries with such high currents on a daily base. Everything over 160A (over 0.5C) is very high and stressful for the batteries. Consider a second battery pack in parallel.
Congratulations 🎉. You have more than 100kWh of storage now? 😊
I think Andy have around 182kWh of battery power.
Battery shelf 44.3kWh
Vertical batteries: 54.7kWh
Polo batteries: 15.3kWh
Server rack batteries: 66.8kWh
+ Tesla
I never did the maths... on the batteries😉
Hello Andy! Greetings to all! I need an advice. Are you using a safety ground on the main negative bus?
What is a safety ground?
I don't have any of my battery terminals grounded.
@@OffGridGarageAustralia victron manual: The primary Case ground connection from a inverter charger must be connected to the Central Negative Busbar of the DC system . Size of this cable must be identical to connected DC Negative.
You da man!
Hi Andy. You are using an external power supply with high voltage output. Most of DIY peoples have no such supplies. I have heard you can control by Cerbo GX via menu DVCC. With current and voltage limit settings. It will help but the reaction time between new settings and actual voltage/current is slow. Sometimes the bms of Cerbo will go stand-by mode. It is irritant. May be you can demonstrate in a next video how to cooperate wit DVCC?
I think most people building their own batteries have such a power supply. Even the cheap 60V/5A PS will do the job and cost around $70.
I have made a few videos about DVCC already. What in particular do you want to see?
@@OffGridGarageAustralia Suppose you want to sell the batteries to customers/families/friends, you do not like to go there every half year to execute a top balance. In this case the DVCC should be ideal as power supply as remote control. However I am still facing that there is several cycles when the current and voltage limit settings are applied. A cycle is charging, idle and sometimes discharge. This cycle take about 1-5 mins. That is not desired. BMS want to keep the voltage like 55.2V constant so it is sometimes charging or discharging. May be you can demonstrate how to solve it.
It is still not clear how can we see any status from active balancer v3.0 in BMS Studio app. Is there a communication between BMS and active balancer using 4 wires on DRY port? What will do this port?
Thanks in advance.
@@erikcoenders100 I don't understand how DVCC can help with balancing. This has nothing to do with it. Not sure what you mean with that...
The Seplos active balancer is a standalone device and cannot be managed. It has fixed settings which cannot be changed or altered. There is no communication between the BMS and the balancer.
That is great insight. I am expecting my 280ah Hithium batteries for a small home project 24v system. I was wondering if top balancing is necessary. Given that I have the Heltec active balancer 5amps, this video has given me insight on what I will do to top balance the batteries instead of putting them in parallel. thanks off-grid garage
Yes, just connect them all in series and connect the balancer. Increase the voltage slowly with a power supply and let the balancer do its thing. If you get them all just over 3.6V, that will be fine for a top balance.
Don't forget to disconnect the balancer afterwards again ;)
i use only Ac In from multiplus 3000 to charge and discharge the lifepo4 to my existing ongrid 66kw pv, all the surplus go to the grid. i m not using any Ac out 1 & 2 and no mppt controler. it takes 7-10 sec to change the flow of Ac in multiplus
Great!
Thanks for yet another great video Andy. Where are you buying your 66Amp breakers? I could only find the 63Amp version😂😜
It's an upgraded version, haha,😄😉
Hi, any idea where to get the Firmware V2 16.6 download ?
On my website, as always😉
Find the Seplos BMS Resources link and follow to the FW folder. There are two files, one is for the BMS with BT onboard and one is for the BMS with BT chip on the display.

Hello Andy, I'm not sure if you've already explained this in any of your videos, but I would like to know if LiFePO4 cells can safely operate when placed on their longer side without enduring damage over time. I also need to position the cells in the same way as shown in your video due to space constraints. Thank you for your response and for your videos.
Yes, you can place them on any side but not upside down. Make sure you compress them when putting on their side.
yesssss
I build this battery in December, It would be so good to have this video when I was building it 😅.
Now everything is working good after I understood the « seplos logic » which is a bit far from mine 😂
If they would have included the manual...
Hi Andy,
Can you share the setting of the Seplos Standing Kit ?
I am curious if I have the right settings for my batteries.
By the way, great content, that was really impressive and nice to see how the battery performs.
Then I have another question, do you know if this batteries and bms can work with a 3-phase MPPT/inverter ?
Because I am thinking of a setup with the Growatt SPH7000TL3 BH 3-fase inverter.
Thank you for the great video and explanation.
Thanks for your feedback. I will do a video in the future, explaining most of the settings for the Seplos BMS and share this on my website as well.
It's always a bit tricky to share that as all system designs are different and my settings may not suit your installation.
And yes, the battery can work with 3-phase inverters. Basically, the battery will not care what kind of inverter you have connected.
@@OffGridGarageAustralia Thank you Andy, I really enjoy your content,. waiting for the content of the Seplos BMS standing kit.
After the first video on this DYI box I checked on the price. Yikes. It is a nice package for sure but I guess I would prefer being more of a DYIer and devise a box (like you did) myself. I have only built small 12v batteries but just about ready to take the leap to either 24v or 48.
The Seplos box is attractive but, personally, not for me.
On the other hand, the Gobelpower cells performed really well. The quality of cells coming out of China seems to have really evolved. It is rare to see any cells test poorly anymore.
The prices are right for what you get. The case, BMS, display, busbars, cables and PCBs... if you add this all up, it's a bargain. Building your own case, box or enclosure is a lot of work and takes a lot of time. Not everyone has got the tools, material and time to do that. So these DIY kits are a fantastic option to build your own battery in a very good looking case.
🙂
Hello🙋♂️
Great video... Seeing you connect a discharged battery and balancing with your charged batteries illustrates a problem I am experiencing. I have five 63Ah batteries in parallel, all with the same voltage showing. Four are approximately the same SOC but one has a much higher SOC and causes the inverter to discharge the others below their cut-off as the inverter totals the five SOCs and divides by the number of batteries. So, as far as the inverter is concerned, the SOC is at 10% (cut off) with four below 5% and one at around 30%. Any ideas of the potential cause?
The inverter is a Lux AC coupled and the five batteries are Hanchu/Greenlynx 3.2kWh.
Hi. The first question that comes to my mind. is why are the Bms boards not shutting off the battery’s that are being over discharged and stopping them from being discharged. What Bms are you using ?
The BMS model code is "DR48100JC", I think they are proprietary and although the settings can be viewed using "Daren High Tech" software, they can't be changed, I think the software is for another product and is not 100% compatible.
By not connecting the "uncooperative" battery through RS485, the inverter ignores that battery (but the capacity is utilised in a "dumb" mode) and the other four work as they should using inverter discharge cut-offs.
@@ColeRV Well that is a work around. After many years of using lead acid batteries . I am just starting to get into the. Lithium batteries. I have just changed my Ev battery. For a 10k mile replacement. So my 115k battery is now being repurposed for the home battery system. So I am just getting into the setup to make it all work. As I want. Biggest problem is I can’t afford to have the batteries decide to go off line. So need to get. Inverter shut down at the right point to leave capacity for the drain of other systems that are running. Before cheap rate charge
The BMS of the battery should shut down the pack when on cell goes under the set limit, leaving all the other packs connected and operational
BUT, with 6 packs in parallel, I would highly recommend having the BMS communicating with the inverter (master-slave config). So, the inverter should know there is a problem with one of the packs and stops discharging any further.
did i miss something? how to reset seplos v1 to 100%? can someone explain or send me a link to the video?
It's in the comparison spreadsheet at the top of the page here:
off-grid-garage.com/battery-management-systems-bms/
@@OffGridGarageAustralia now i know why mine never reset to 100% the Total Voltage Overvoltage Protection is set at 57V but the sma sunny island takes this value and makes 56V out of it. so it will never reach the 57V of the bms. well than i have to live with the 98%
SEPLOS COME ON....
Yes, in this case you're screwed with the Seplos BMS... and they won't provide any further updates for this BMS any more. 2.9 was the latest but I would recommend sticking with the 2.8.
@@OffGridGarageAustralia the 2.8 is not good for sma, have tested this. so i will keep the 2.7....
but i am using the stuart diy bms and the seplos is the second stage(and backup canbus device) if something goes wrong with the diy bms.
so the diy bms report the real soc to my venus os
Wao Andy, how much KW/h capacity, do you have currently available in your system?
All for testing purposes. I never counted...
Already more than in your Tesla, for sure
That's what happens when you do late night battery assembly. I'm glad you stopped to look.
It was very apparent that there was something wrong.
I don't think it should automatically update the rated capacity. But it does have a field for capacity. That one should update.
If you are wondering why I'm saying that: you should be able to see the intended (rated) capacity with the actual capacity.
Yeah, I get that, rated stays at 280Ah but actual should update... well, it didn't, not even after a full charge again.

Oh, yes, wow. that went quick!
Andy can i connect with my 280 ah seplos diy kit another battery kit with 105 ah batteries and seplos also bms ..
.you think better to connect them with. Communication caple or not .? thanks
As Andy discussed in this video, the only issue you will face is that the master assumes all other packs are the same capacity.
Andy has a 135ah pack paralleled with a 280ah pack and another 280ah (or was it 304ah?) pack, and the master (the 280ah pack) assumes all three are 280ah.
The hodge podge collection of packs seems to work fine, if you watch other videos Andy has made on the setup.
I have 280AH pack connected with two 105AH with all 3 different types of BMS no communication needed between them. working great for more than one year. and 3 years for the other 2 packs.
The packs even divide the current based on capacity.
Yes, you can connect different capacity packs and have them communicating to each other. All batteries need to have the V1 or V2 of the BMS (V3 is not talking to V1 or V2). I have V1 and V2 talking to each other just fine and any can be the master.

How do you get the good translation with ‘single’ instead of ‘monomer’?
They use both words. After many years of reading these manuals, you just get used to it... Their English is still better than my Chinese.
@@OffGridGarageAustralia yes, but I mean where you have ‘single’ I have ‘monomer’; is that a firmware thing?
@@jacopo.scarpellini yes, they changed the wording at some point from monomer to single.
Top balancing it like to build the building on a swamp. Totaly wrong ;) from 3.45-3.65v it a swamp. Bottom balancing .Higest cell little bit +30mv, lovest cell -30mv . balancing start fro m 3.5V!!!! cell protection 3.55v. Charging 3.45V Works perfect. Balancing never turns on coz all balanced;)
Bottom balancing was 15 years ago! No equipment supports that any more.
Hi Andy, the active balancer from Seplos seems to be a bottom balancer according the specs. Start balancing voltage is 3,0V and stop balancing voltage is 2,9V. Therefore it is not my choice although I just building up my battery bank with 2 Seplos V3 BMS.
@@stephantitze8302 It's a top balancer. It only means, that it will stop balancing if the voltage goes under 2.9V to stop further discharging the batteries. It then start balancing again at 3.0V if the voltage delts is higher than 50mW.
Not great.
i have a problem:
I made a package for my scooter from 72v 36a 6000mah 32700 batteries. I used jk bms lifepo4. The datasheet of my batteries says they are 3c max. But some of the 24 series experience a lot of voltage drop. Around 10 of them. These are 2.8v while drawing 42 amps. The others are 3.1v, 3.2v. I removed my package, my centers seem to be intact. My batteries are all new. I balanced
Sounds like some batteries don't come up to spec. Have you tested each individual battery capacity?
How are they connected to each other. Fully top balanced to 3.6V?
@@OffGridGarageAustralia I solved the problem. You won't believe it. I didn't put the balance cable right in the middle of the 2 batteries. I put it in the corner of one of the 2 cells. That's why it calculated the internal resistance of the cable and nickel strip incorrectly. The cells worked fine.
