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!
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! 😃
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 ?
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 😉
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.
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
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.
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) 🍻👌
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.
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
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.
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.
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.
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
@@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.
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
Interested in the new Dakota Lithium DL+ 12V 60AH batteries. They show 100 A max continuous discharge, 750A max 2 second pulse, 650A max 5 sec pulse. Looks interesting for starting applications (golf carts or similar). See how many 🐸 it can get.
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.
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...
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.
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.
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
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?
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…
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
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,
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.
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.
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.
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.

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)
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...
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...
@@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 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.
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.
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.
@@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)
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! 😁
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 RU-vid deleted them, but there is a web page that keeps track of the version download links for these.
I do not like the idea of recalibrating a S.P.A.T. A used S.P.A.T. seems it might introduce problems. I'd prefer to start with one fresh from refrigerated storage each time so that each calibration is fresh and the S.P.A.T. is not subject to unknown wear or contamination.
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 ^^
@@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’m not sure to understand. If I use 16 cells of 3,2v. 280 ah. It make approx 14 KWh. If I use only 2 batteries like this how many AH I will get ? Ratio of power/price use is low isn’t it?
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.
