I believe one of the reasons it is cheap is the BMS doesn't have low temperature (cold) cutoff and isn't a smart Bluetooth BMS. But if you live in a warm climate I wouldn't worry about low temperature cutoff. It looks to me like batteries with outdated BMS's are being cleared out for a bargain.

lmao... 'a few more' - sure thing, bud...
Here are a few similar but 'made-in-USA' 12V/100Ah LFP batteries - just a few bucks more @ $650-675.

https://www.bioennopower.com/prod...lf-12100as

...not that I'm suggesting anyone buy the cheapest no-name China-direct batteries they can find. There are more reputable options available without breaking the bank.

"Made in USA" - lol. The cells, the BMS, all come from China. All they probably do is connect the BMS to the cells here.

OP thanks for sharing. This is first time I have seen less than a $1 per aH.

I wouldn't really recommend a no-brand like this, at least, go with Eco-Worthy.

The FDA disallowed drug names from conveying their function some years ago, which is why we get Latuda. You'd think it helps with flatulence or something.I have zero experience, and there's plenty of good Youtube content on this subject.I'd be comfortable with any brand because as was already mentioned, they're all using the same components anyhow.My curiosity in these LiFePO4 are for a trolling motor (which I don't have yet), or to replace the battery in a vehicle.
Not for vehicle start up battery by any means

Quote from SeanD1497 :
The dimensions or physical size of this battery are unclear. Pics here show two different sizes. Size does matter sometimes, not just the capacity; I bought a pretty large one for a solar generator project, and immediately wishes I had shopped a little more and found something smaller. If I'm reading the confusing listing correctly on their site, this is a 13" long battery, meaning it is pretty large.
I posted earlier that it looks like group 31 size. From what I'm seeing, these 12v LFPs are mostly available in Group 31 (this larger size), or Group 24, both with 100 Ah capacity.

Strangely, I found Group 48 LFPs that are much larger, but have less capacity.

Yeah, I had been looking at mostly group 24 batteries and planned my build for one, then jumped on a good deal for a Group 31 battery and ended up wishing I'd found a Group 24. Group 48 batteries are found in some European cars (I think my old BMW had one). No idea why some batteries are so bulky, especially when they're much lower capacity than some smaller ones.

Do you mean like for remotely monitoring the cell voltages in the pack, or checking the charging status or amp draw when they are down in your RV or boat battery compartment? Or when you are using it as part of an off grid solar battery bank? Do you know what these batteries are used for? This is not a car battery.
Motorhome, check. Boat + x2 trolling motor batteries, check. Electric riding mower, check.

Need to obsess over battery condition....*crickets*. I got better things to do than act as a battery cell monitor. That's the job of the battery charger.

I don't trust Aliexpress. The shipping never om time!

Wait, so you're saying you do buy from there multiple times, and you're only upset with the delivery time. It sounds like you have your expectations managed, and it doesn't sound like you don't trust them, you just know what to expect

Looks like a good price but has anyone used them before?

I bought a $300 radar detector last year from AliExpress. Seller provided a fake tracking number that my post office told me was wrong. AliExpress, PayPal, and my cc company did nothing.

Any reason 3 of these wouldnt work for an older 36V EZgo golfcart ? Seems like a helluva deal
these will not work with the golf cart The BMS is aren't designed to take the amp draw that a golf cart requires it usually takes 250 to 300 amps for golf cart to take off which will trip the BMS even if you have three of these chain together

With that said, batteries are constructed for specific applications and there are trade offs (battery life, high current output, size, weight, vs. cost). These seem to be designed for longer battery life and lower cost at the expense of that they can't be used for high amperage charge/discharge applications. Also some battery chemistries are better than others in each of those categories (long life, high current output at the expense of high cost).

anyone know if you can submit three orders for one battery each (I need three of these for trolling motor). Don't want to get stuck ordering one and can't get 2 and 3 at a discount... never ordered from them before.

I really want this in my hyundai kona EV but it's 14.4 +- 0.2, Kona charges at 14.7-14.8. Since it's not an alternator it's always full power which often times might burn out this BMS, why don't they make lifepo that supports higher voltages!@#??

Im sure you ordered from a really reputable seller too. Maybe learn how their site works before sending them $300.

Doubt this hits capacity, likely B grade EVE cells. BMS can be swapped. Anyone not confident to do that if needed shouldnt be buying things like this anyways.

In Italy, to have "MADE IN ITALY" all they need to do is the last thing such as stich a zipper and now the entire purse is "made in italy". I expect the laws to be worse in the USA. I think now in Canada, if you bottle the subject in Canada you can say MADE IN CANADA... so if you buy oranges from FL and process them in Canada, you can now say 100% made in Canada Orange Juice.
I have a HUGE issue about "made in"
