Next-Gen AoLithium 12V/100Ah Battery. My honest (and different) review!
Вставка
- Опубліковано 29 чер 2024
- #AoLithium has send me their 12V, 100Ah LiFePO4 battery and asked for my opinion. Well, here it is then. I have had this battery for over 4 weeks now and have used it in the garage to power an inverter and do all kind of tests with it. It's a great product and I really like using it. It has app access, I can change parameters, can open it up and it delivers (just) enough power to even charge the Tesla! Wow.
Next to the traditional tests like capacity test and S.P.A.T. test, I have tried to come up with some other test you will only find here on the Off-Grid Garage channel. I really wanted to break out of the usual (and same) battery tests you find online and mix these with a good portion of entertainment and fun!
The #AoLithium battery is not perfect by any means and there is lots too improve. They are on a good path and really could make the Next Gen battery and I hope over time they will get there, learning from this project and taking all ideas but also critisism from their customers on board.
Enjoy the video and leave a Like if you... well, liked this different style of battery review.

Thanks for your recognition for Aolithium Batteries! We humbly accept your suggestions and criticisms for our products, and we are going to continuous improve our products and services to satisfy all users!
Thanks for making such a good product. You're on the right path!
AOlithium I would like to test your battery in a 6 week trip in my oldtimer camper. I will spending 3 weeks above the Arctic circle and will have cold weather and snow. Let me know if you are interested! 😃
Your price needs to come down !
Sorry, but a doubled discharge rate adds a lot of benefits and therefore make people buying those with such high rates other vendors do not offer and willing to pay more.
Here it is called fraud - no chance to get rid off that fraud the prosecutor will let investigate deeply.
Imagine Porsche would claim their Taycan would be double as fast than the Tesla model S they need to proof it.
Now it is too late
It needs to more to get the reputation back and it also ruins the reputation of chinese products especially in the battery segment where we in the west get only not A grade cells except we buy directly from EVE or CALB, all other vendors are selling used cells or not grade A cells they had purchased from auctions in china. Therefore we do not get a batch of 16 cells with following production id's of one batch, no we get cells with production dates from 3 to 6 months, even from last year or 2 years old .
That is the reality we face, of cause dealer offers with OEM LiFePo4 cells they sell as 105 Ah and say they had been tested with 120 A. Which company has such giveaways of 15% more ?
These are relabeled cells of brand manufacturers of 120 Ah cells a bit used and they get a 105 Ah label so that the customer will see that the battery tester will exceed the 105 Ah nominal, which could make customers lucky - or let others feel insecure.
Your cells might deliver the capacity but the charge and discharge rates are key for us how fast we can charge EVs from our batteries.
Sad but true.
I'm keen on your battery's, but being In Australia, most lithium battery companies dump B grade cells , are your cells automotive grade ? If I was to buy your brand would the QR CODE , be ligit and is the QR CODE THE SAME ON THE CELLS AS the outer case ?
You promised us no changes to the format of the channel and yet here’s a change to the format of the channel! Please keep this up!
What? The Tesla advertising? 😄
Loved every minute of this video. Love your sense of humour and production quality. Excellent and honest review. LiFePO4 batteries are certainly a device where real world experience trumps marketing and your thorough and practical tests are very much appreciated. Love the addition of FLIR photography/video. 4.8 out of 5 frogs from me. The fact that 2 * 2 cells have welded cells in series prevents a manuel, parallel balance is a design fault worthy of mention.
Awesome review and no frills just the truths. So many reviews on YT biased imo just so they can get free gear. Keep up the great work Andy 👍
I appreciate that!
I love the "I'm German, 5 is impossible to reach" @38:31 lol I think the same way most of the time.
A 5/5 is impossible. That would be the perfect, I mean perfect result with everything being perfectly designed and made.
At 17:00 , The sensor is likely calibrated for frozen green beans, not Spat.
Arghhh, nothing I can help with 😂
Thank you for the humor Andy. Always welcomed in these different times.
Thank you, always trying new things ;)
This was a great review. You highlighted the good and bad on the battery and the company seems to be receptive to your criticism (shown by their comment here). If other companies offer to let you review their products and allow you to give an honest opinion I hope you take them up on the offer.
Thanks for your smart and humorous twist on testing and rewiews. Go on Sir, just love this. Greetings from Norway :-)
Andy, this is your best video, hands down, ever !! Keep up the good work !!!! 😀
Hey Andy! Great honest review! I wouldn't mind seeing more!
This was your best video to date! awesome job!
011822/0029h PST 🇺🇸/011822/1829h Brisbane 🇦🇺 Good evening Andy. Err the opening of this video made me think as if you were on Safari in Kenya. That was a dramatic overture. Thanks… it brought smiles for a few minutes. The welded posts a big NO NO, indeed. But for me rest of the issues were like what many have observed in normal battery assembly. I, still prefer, assembling the cells by self. 4 of my power systems are my own assembly and proud of it. Though meager, 3.5 years of continuous use has been absolute zero issue.
Thank you for the product review and the time taken to exhibit for general public. Take care und 73s…
Thanks Sree. I also like building my own battery but for mobile applications, this is great. Or like the Bluetti, you can just take 1.5kWh with you and have a built in 1kW inverter. I use it all the time. It's my generator.
011922/1127 Brisbane 🇦🇺 Thanks for the introduction to ‘BLUETTI’. If you say it’s good, then it is. I watched the introduction of that device. Now BLUETTI is in my list. Thanks once again. 73s…
@@sreekumarUSA there is a link in the video description 😉
Great honest review! Thanks for doing things differently than others on YT!
Thanks Edward.
Great review Andy . I really enjoyed every single second of you video . Gret job and fun video .
Thank you for your time in this Review. This is what we need Honest review, I hope this makes then step up their game, they are not far off.
Hi Andy, The intro came up great, worth the effort. All so great review, Thanks
Thanks 👍 Yeah, a lot of work for a few seconds of video. But I love it...
I watched a couple of other reviews and genuinely LIKED the AO Lithium battery. Sweet busbars, nice bolted connections- well designed and laid out. It can probably do more output/charge than listed...Also, good to see you! I've missed the Off Grid Garage, Andy!
Thanks David. The Aolithium battery is certainly one of the better batteries out there. I'm currently testing two others and they seem to be very average in comparison.
Hey, I'm still here and publishing videos a few times a week 😉
Careful dude, you're getting into my video length territory! lol! Glad to see you having fun with this. ^_^
Hahaha and this was the short version 😉
Just purchased the 300ah aolithium. It has no Bluetooth but claims also 200 amp discharge current. I’d love to see this battery tested. Black Friday deal was $1000 CAD! A great deal for 300ah.
Merci ANDY, pour toujours permettre au utilisateur de connaitre ton point de vu technique réel et précis dans une méthode pleine de perspicacité...🙃
Merci beaucoup.
excellent excellent review andy!
looks like aolithium could be on to a decent thing if they take notice of your review 👍
loved the style, not taking yourself too seriously, but still delivering the facts required (echo your thoughts on this being a great RV battery if they can bring the current draw up a little more) 🍻👌
Awesome video. Great information as always.
Thanks again!
Many thanks for this outstanding video. It will take hours to get rid of that big smile in my face!!
Back to the battery.
For me it looks like every time, marketing people create the spec sheets without asking the technicians.
Let`s see if they follow their promise to improve that product.
First and easiest step should be the ability to exchange anything within the case.
@24:14... finally a "test" @ Will Prowse hasn't posted, yet. Love your Humor Andy !!
😂😂😂 You need to go to the extreme!
I like that Tesla advert.
Yeah, that was fun to make 😄
Good honest review.
Great to see miss Piggy and Kermit in one episode.
Hahaha, yeah!
LOL Thank you again. Still remember the low temperature test LOL
Well done on this video. Being asked to do a review comes with a lot of conditions and pressure, and I think you managed to do that well. I recently did a test/review on a locally made battery, and due to a technicality in the conditions that I agreed to, I was not allowed to disclose the results. I have to agree with your findings too, being "serviceable" is one thing, but it needs to be easily serviceable, and this one does half of that. Next I'll set aside a couple of hours to watch the other videos :)
Nice to see you using one of those Renogy inverters too, they're pretty amazing for the price.
Thanks Paul.
Oh, so you are not allowed to say anything about the batteries they want you to test? Aolithium didn't come with any restrictions, they just wanted my honest review. That's why I said yes.
When working with these batteries, I always think of the batteries you are building with 250A continues discharge current and how far advanced your batteries are. No wonder they sell like hot cakes!
@@OffGridGarageAustralia yeh it was my mistake by not reading the wording properly. I said that I would discuss any negative results with them prior to mentioning it on my page, and they changed it to being that I would not post any negative results. There was some argument and even threats made towards me, so I posted about my interaction with the business instead, which in the end was much worse than the battery review.
The "continuous" ratings are tricky. Even mine will get pretty hot when run at 250A, or even 150A. If they were used like that all day every day, it would be a bit of an issue with heat. However the majority of people will only run them at those high currents while cooking, and that's normally for 10-20 minutes. Anyone wanting to run really high current loads should be using more than one battery. I have people putting in up to 4 of these in parallel making about 14kWh of capacity. :)
I'm already taking orders for builds happening in 6+ months time. And the next 3 months worth of batteries are sold out. It's crazy!
Great video! really appreciate the in-depth content and reviews you're doing.
You've just got yourself another subscriber and beer supporter!
Regarding the Aolithium battery itself, how do we get them in Australia?
There doesn't seem to be an importer and when I inquired directly with Aolithium, they quoted a shipping cost of $300 (per battery!)
Any insight you might have on this would be appreciated!
Cheers,
Tom
A greate and entertaining show and a trustworthy test - thank‘s a lot! 5 out of 5 frogs to you ( not the battery) :)
Thank you, Peter!
Andy your distance measurement remind me of an Army cross country measurement system. Very good work on the battery.
Thank you.
Thank You for All that you are doing for World Peace and for our Planet...
Peace.. Shalom.. Salam.. La Paz.. Namaste ..
🙏🏻 😊 🌈 ✌ ☮️ ❤️ 💐 🕊
The welded terminals are a good idea. Ok that means the cells can't be swapped out but on the other hand they wont come lose inside a sealed plastic battery box. The build quality is nice.
Love your videos
Thank you!
Hey Andy, nice review! I still like my own cells. Keep up your cool videos! I have a question: Are you going to build a thermal control system for battery 3.0? Liquid or just air.? I know in Australia you dont really need it but it would be really cool! Lg
Thank you.
I think the easiest way is to use these heating mats under the battery cells if you live in colder climates. You also would need to insulate the battery a bit, I guess. It's a bit tricky as you don't want them to overheat in summer either... I'll think about it...
Great video. I wonder if Will did not make the test video, would AoLithium come out and make the correction?
Great review Andy, I was thinking maybe the temp was incorrectly labelled Fahrenheit ?
Hi Andy, thanks for your vlogs. The aolithium claim that the battery can be put in series and parallel was not tested, it would be nice to see if they have exaggerated this claim? Maybe a future test?
I would need a second battery for that...
Excellent Review Andy and thanks again. I would be interested in knowing if you noticed any self-discharging going on with that low #4 cell? I just bought some LFE cells and all but two of 12 cells came out of the box at 3.1V to 3.2V, with one cell was at 1.2v and the other at 1.98V. After top balancing they seemed to deliver full capacity but after a week the same two cells that came out of the box low, had self-discharged to about 3.0v while the rest were at 3.4V
I have since put another cycle on this battery and could not find any problems except the lack of good balancing through the BMS.
Imagine If the capacity would have been only half of the promised capacity. No way aolithium would survive..... thank you for the Video and the very fair review
They will have a hard time with this battery and the initial announcement of 200A discharge current already.
So obviously the BMS is acting upon all the temperature sensors (there would be more than 1). The software however is only displaying the hottest sensor as that is what is usually the most used.
Yes, the BMS has got two sensors, one external and one build in measuring the FETs presumably.
super video , bin neidisch auf das wetter bei dir :-)
Danke Dir. Das war ein Grud fuer den Umzug damals...
I have found any limited warranty on a battery pack is practically nonexistent if the system is not installed by a licensed, bonded and insured professional installer. This is often actually expressed within the limited warranty wording. As a result, I always proceed as if there is no warranty as I do not have the months required to jump through all the hoops the manufacturer requires. The only way that I could get warranty consideration was to purchase the charger the manufacture preferred and test the resulting charge. It cost me $200 to get a $500 battery replaced. Still I am happy because I now have a working battery and a nice charger. All that aside, I have been denied any warranty assistance many times and have succeeded only once. In many cases the manufacturer did not even ask me to ship the battery back to them which USED to be the first step in any warranty consideration concerning electrical equipment. I think the trend towards ordering online holds much misery going forward in regards to warranty help from a manufacturer.
Tap on the blue temperature circle to see all the different temperatures sensors
I know you can see the other sensors as well. It does not make a difference, they won't go lower than this 26°. The other temperature does not change at all...
I like the longer videos. Keep them coming please. LoL 😆 PS I don't know why a company would sabotage
Their company like that. But! With two cells permanently bonded and each cell takes 100 amps that makes two hundred amps. Don't make any sense
The cells are in series, so the current is the same in all components.
Love it!
Thanks!!
The fact that the case can be easily opened and batteries replaced is EXCELLENT, but the welded pairs is not ideal.
If the bus bars were slightly larger and the software open source and available for linux that would be brilliant
Maybe It's Fahrenheit! Great Spat calibration! Thumbs up and subscribed!
How many times have you subscribed now 😂
Danke Andy für das Video :) The small 12V20Ah would be a perfect solution for the Teslas with dying batteries. I'm having a Winston 12V40Ah with DALY BMS in my Model S since Nov21 and the setup works more than perfect (40Ah is an absolute overkill). So I would give this AOLithium a try ... but shipping to Europe is horrible: $300 ... no thanks. Herzliche Grüsse aus der Schweiz
@@josepeixoto3384 Not traction HV habtteries, but the 12V has been a weak point. Now they start using a LiIon in the new Model S and Y.
Thank you for not being a will prowse when it comes to opening up batteries
Where do I get your ice-cold SPAT? Oder geht auch Flaschebier?
Nice Review, mach weiter so...!
Yes, bottles work as well 😉🍺
Hey Andy where in Australia can you get these batteries ? , do you think you got a hand picked battery from the company that was perfect , ? Wondering if all there stock is good , what a ripper job you do , such a happy person and entertaining,
replacing components is important if you buy the AO battery for all your usages. If you buy 10 or so batteries, and one has a BMS failure, another has a cell(pair failure), another has a broken case, etc, you can salvage parts to keep things going. I've done this with many other products, cars, air compressors, etc. I buy the same item, same year, to have a "salvage yard". When my parts supply gets low, I scrap and start again with a newer model.
You might be on to something with the solar panel hooked directly across the battery.
Improvement of the buss bar is a must.
If AoLithium made a version with an inbuilt MPPT solar charger with BMS, it would be popular with 4wd people and campers.
Like the Bluetti. It's an all in one product and connects to any DC power source to charge the battery. It also has a 1kW inverter build in.
3.4v is a bit low for balancing, but not bad. That would be a 13.6v terminal voltage. I'd prefer to see 13.8v but I can see 13.6v as a "make sure that a float charge voltage will balance."
I just finished a rebalancing of a drop-in 12v replacement LiFePO4 battery. By deduction (I cannot see individual cell voltages) at least one cell was very low and instead of being able to charge the battery to 14.40 volt and hold, the BMS was shutting me off below 13.7v. It took almost a month of days (I did not want to leave it unattended) to finally get to 14.4 volt pack voltage.
The balancing function is not good in this BMS (see future video). The good thing is though, you can just change these parameters to whatever you like...
Good morning, Andy. The battery must have been delivered by a small UFO. Have a nice day.
Made the grass flat, right?
There has been a video about how it landed.
Great Video. Watched you & Will’s vids. Battery is Impressive. Just don’t know that I can justify that Big of a Price Jump over other (Good) brands, just to have impressive 2C discharge capability.
Nice work you are doing there. My major concern with the battery pack is that the battery connector is welded and that means one cell can not be replaced which is a down side.
Yes, that is a design, I have not seen before either.
Awesome!!
Hi Andy! Have you ever considered seplos battery or bms for your batteries? They have a communication port which should be compatible with the Victron system. The only flaw is that they are passive. Cheers
Well, either everyone still loved it and bought them all, or they have taken them off the market to make the improvements already becuase the Amazon link you shared says their entire range is currently unavailable
Oh, wow, you're right. That is insane. They have taken it off the market apparently. I wasn't aware my influence is that big .🤭
On most thermal cameras, the Emissivities ε is set to 0.95 or 0.90. But for non-coated aluminium, you would have to change it to around ε=0.3 for accurate readings :)
Or you just take a Edding and paint it black before measuring ;)
It was very entertaining Andy! Thank you!
About the battery:
- Die Zellen sollten auf Dauer nicht auf der Seite liegen, sondern stehen, soweit ich weiß.
- Eigentlich ist es gut, dass das BMS überdimensioniert ist. Aber man sollte natürlich nicht mit 200A Dauerstrom werben ^^
Thanks Raphael. Does it say that in the cells specifications that they should be upright?
@@OffGridGarageAustralia Well, I did not find the info in the datasheet of those Aluminium case cells. But the presure vent should not be under electrolyte. Thunder Sky Winston batteries should be in upright position (terminals mounted to the top) because of a shorter service life, if mounted sideways. But maybe the Winston cells are a bit different from those aluminium case cells.
I have the same thermal camera. It sometimes reflects on aluminium and glass. it also wont read through glass. for shiny surfaces put some tape on it to measure the temps if the surface isn't reading right.
if the BMS have multiple temp sensor, normally xiaoxiang will show the highest temp only, you can tap the temperature display, it will show you all the temp sensor parameter in the BMS.
I've never seen this for the QUCC BMS and it has several temp sensors too. I'll keep testing this. Thanks.
@@OffGridGarageAustralia I have the same BMS that what you using now, you can just tap the temperature icon, then you will see all 3 temp sensor value. (2 sensor on the circuit board, 1 external low temp sensor for battery)
Thank goodness for Will Prowse.
Is there room inside to add a separate heater and drill/seal the leads from the outside for powering the heater? There are cold climate users that would love to heat the batteries without using the batteries power. It's stressful to be using your battery in the winter, knowing that you will not be able to charge it. Heating from inside the case is easier than heating the outside. The case is a thermal insulator.
The fact you can only use 2 in series is a deal breaker, especially give the faux serviceable cell configuration
Exactly what I was going to say. Nice for those using a 24V system but we all want to keep our current low so we save on cabling. Right?
Yeah, that's definitely not a good design and makes this 'advantage' useless.
Yay!
A spot-weld drill bit will enable users to remove that whole bracket and re-use it if necessary.
Ah, you mean you drill out the welding at the terminals.... but how do you get the busbar back on? As per my understanding, this welding creates a lot of heat which is fatal for the electrodes and battery.
@@OffGridGarageAustralia It would allow replacement cells with threaded terminals to be used. I don't know anyone in their right mind that would attempt to weld onto a LiPo cell, but I'm sure it would make for some great video content! 😁
@@mediocre_moto hahahaha, yeah for sure. But that's not me😂
JBD does have a good bluetooth adapter. The BMS is also very good. The 100 amp charge rate is a cell limitation, not the BMS. 3.4v is the normal balance voltage, and I think the balance is "up to 150 milliamps", but for good cells it is very adequate and works well. I am not sure "normal use" is 100 amps, most people want the battery to last more than one hour. Perfectly adequate for 80% or 80 amps charge/discharge cycles with occasional 100% use. The BMS is a standard JBD BMS and can easily be replaced, you can even buy it with a heater interface, which allows it to power a heating pad when below freezing before allowing charging. The BMS is rated for 200 amps, as you noted, the cells are not. I have both models of this BMS and it's displaying the FET temperature sensor, not the external.
If this is a JBD-SP04S034 200A BMS (looks like it), the Xiaoxiang BMS app reports it correctly with three NTC temperature sensors. Two are on cables (or connectors on the side) and one I assume is on the FET.
Thank for the insight, John.
This one has only one external temperature sensor. The app shows only rising temperature correctly, not falling. if it shows FET temperature as minimum and external temp as maximum, well that's a bug then.
If press the top left corner in the app for the menu, there is a menu option called Battery State, it will show the other temperature sensors. At least in my setup. Maybe one there will show the beer probe.
@@Dan-LS It also depends on which version of the app. I would post a link, but UA-cam deleted them, but there is a web page that keeps track of the version download links for these.
@@OffGridGarageAustralia I had to try more recent versions of the app until I found one that supports the BMS.
Thats fun
Great scenery . I don't hear any frogs
Far too hot for them during the day. They come out at dusk...
Thanks!
Thank you very much John!
I finaly got all my EVE batts I now have 1120 ah 24v 28 kwh running 4X daly's bms i never had an issue connencting them to blutooth either.
That battery looks great EXCEPT......
I see no padding/vibration resistance.
I was looking for high quality good value 12v battery(s) for my RV, I think this battery is great for a stationary application like your garage, but for an RV with vibration from travel, probably not ideal.
It gets clamped down with the metal plate but only has these yellow insulating material, no damping. I guess if you put padding in such a battery you also thermal isolate the cells which could be good in winter but bad in summer.
In an RV that has room for a bigger lead acid battery, it makes no difference if the padding is inside the battery casing or around the battery.
Looks like printing dept made a mistake.They seem to be missing technical personal. Most batteries have a long pulse (double current for so many min.)and short pulse (triple current for x seconds)
They do as well. If you have a look at the specs for these batteries you can see that it can deliver 200A for 3min and 300A for 30s.
500amp / 5 Sec. Well done AO .
i have yet to find a Chinese app that works right. typical on over rated. i would use it in a car 60 amp chg and 200amp to start (pulse load). but it does look like a very clean build. not just stuffed in a box with some glue to hold it together. good temp for1C 2C not so good. not to bad of a price.
Hi andy great review, the link in the description goes to a renogy inverter though👍
Thanks, what link do you mean? I checked them all and they all seem to go to the right destination.
@@OffGridGarageAustralia it could be a country thing, I’m in the uk, when I click the link it takes me to a 12v 3kw Renogy inverter. Very odd.
@@RustyRoseAdventures So that's the Amazon link then, right? I would say the Aolithium battery is only on Amazon US at the moment and it redirects you to a 'similar' product on Amazon UK.
I’m here Alibaba!
I’m about to order 8 LiFePO4 304ah cells from Shenzhen or something like that. Did you feel nervous over the language barrier? My knees feel weak.
IndiANDY Jones,,,lol, love the intro
At least in the US, that wouldn't void the warranty unless you made a change that could be shown to cause the failure, like if you could disable under voltage protection or change it to a very low level and then you overdischarged it.
Can you do a review and set up on CAnBat
SOK battery let's you open the case and their batteries are fully serviceable.
Hey OGGA, is AOLithium still active and have good customer service? They seem to be much less active online..
Careful with the flir camera fooling you , sometimes some reflective surfaces are picking up back ground reflection temperature.
Yes, that is correct.
2 temp sensors? shows whichever is reading the highest?
mine has 2, click on the temp, you can pick which to display - but maybe AO is different.
Have seen this feature on my QUC BMS before but didn't think about it here. The AOlithium app doesn't have the option anyway.
11:32
Device Model: AL12-100 N815-0001
12 = 12 volts
100 = 100AH
815 = August 15
0001 = unit number for that day
Great, thank you!
And its over 600$ US, i can buy 300$ 100ah LifePo4 batteries all day now !
Yes, that is true. They may not come with the features and built quality though.
@@OffGridGarageAustralia actually, I have 8 that are close... exactly as nice? No…Twice the price ? , come on ! Worth it ? Three times? Battleborn ? ? Sure we’d love them all , but worth it ? No… needs to come down in price. I love the battery just can’t afford it. (Well, I don’t love the welded cells…). Love your channel!
I like the look of that battery. Why is there a parallel limit?
I don't understand this either. From a technical perspective there shouldn't be. Same for series connection. I talk more about his in the following video.
@@OffGridGarageAustralia Series is restricted by size of FETs, I heard
Yes the voltage class of the MosFets in the BMS limitting the series connection. When one BMS switches off for some reason the full voltage is over the MosFets of this BMS
@@andig69 should the voltage not be interrupted altogether by one BMS shutting off?
@@OffGridGarageAustralia if you use more of these batteries in series and one BMS switches of (because of overcurrent protection for example) then the MosFets of this BMS have to block the voltage of the complete series connected batteries. And depending on the used MosFets this will be a problem.
Heya, lol I have to replace my 12V car battery could I use this aolithium battery for that ??
You can replace single cells if one fails just hack the batt off if it's dead anyway
These batteries have problems and I believe it's due to some cells having higher internal resistance (or BMS?). They don't charge to the proper voltage. I have tried multiple high quality chargers and charging always stops on about 13.4v. And that resting voltage diminishes further when the charger is removed. I just received these and have yet to fully test them but thus far it seems like they are selling defective batteries.
Looks Like a liontron battery that are Sold in Germany
About temp display: maybe there are two sensors and always the highest one is shown.
If it’s like the QUCC BMS, there are 4 temp sensors but the app only displays the one with the highest temp.
Good looking battery, but I real don't like welded terminals much.
Yep, me neither...
Pull ice in the Spat, I worked in a calibration lab, years ago. You need the ice.
🧊 + 🍺 =👎
If you drink slowly in sunny hot Queensland Australia, ice is necessary.
A double walled glass works really well(I've got a spare one for you here Andy, but you'll need to trade in the jam jar).
@@andrewradford3953 I remember Sunny hot North Queensland, first year there got there at Christmas from Victoria. My head was going to explode, luck we had a pool and spa to climatise for first 3 months, not to mention the North Queensland beer.
The most disturbing thing about this review was watching a grown man drink a perfectly good beer from a juice glass….
I usually use a reused mustard glass 😉
Do you think internal resistance changes according to state of charge, respectfully.
Yes, it does. Internal resistance is usually the lowest between 20-80%SOC. At the extremes, Ri rises a bit. It will be in the next video.
