Keeps my Sailboat powered

Bought this 12V, 12AH lithium battery in August of 2024. Worked great for the rest of the summer. I used it in a backpack sprayer and have charged it maybe 25 times. Went to charge it up in April 2025 to get the sprayer ready for use. Battery would not charge. Got an error reading on my charger. Tried a different battery and sprayer worked fine.

This battery packs a lot of capacity into such a light, tiny size! I got this in and it was at 13.31 volts, or about 80% charged, and I hooked it up to my 12 volt DC to 120 volt AC + USB inverter so that I could fully drain it before recharging to test it out. I used it to charge my phone, my laptop, two camping lanterns, a USB power bank... Emptying this beast took three hours, and charged almost everything I had to throw at it! When it finally did get low enough that my inverter shutoff, at 10.7 volts, I put it on my digital 10A charger that keeps track of how many Ah of power the battery absorbed while charging, and two hours later when it was full again the reading gave 11.4 Ah of power, which is spot-on, considering I did not actually drain this until *completely* dead before recharging it, due to builtin low voltage cutoff of my inverter.After this was emptied again I hooked it up to my 50 watt solar panel charging kit and was able to get it back to full in about six or seven hours of good sun, which is pretty great, being able to finish it up in a single day. I am definitely excited to have this as my new main camping battery for storing up power to keep my gear going. I also like that, according to the manufacturer specs, this has a maximum continuous discharge current of 15 amps, which is higher than the maximum of 12 amps most 12Ah batteries give, so it should be good for some pretty power-hungry applications, if needed.This has been cycled a few times now, on the AC or solar depending on where I'm at and how much time I have to wait, and it has always given huge output and then charged back up fine, never getting hot or giving me any trouble at all. For how much capacity this packs into its size, and how reliable it has been, I could not be any happier. This is excellent and reliable, and very much recommended! 5-stars!!

Paired this with a 24v 86lb thrust trolling motor. It drains very quickly. It would be nice if there was a battery monitor with it. I bought a $16 one off Amazon to monitor the voltage/current. Voltage drops by 10% with just the monitor attached to the battery after just an hour. Trolling motor not attached.I am not an expert in LIFEpo4 batteries by any means, but I thought I would have more Ah life with this. (Seller said my motor was too big for the battery and told me I need to buy a second battery.)3/5 stars.

This battery provides all the benefits of LiFePO4 technology (long life with proper use and maintenance, high energy density/low weight when compared to lead acid batteries, and excellent safety profile). It's price point, at time of writing, is comparable to many less capable LiFePO4 batteries which makes it a great value. The BMS is pretty standard preventing over-discharge, high temp discharge, etc. There is no low temperature cutoff and it is recommended not to be used (or stored) at freezing temperatures.

Battery worked well for a couple months and now it reads 24.8v when hooked to a multimeter but as soon as any load is applied it drops to 1.2v so I would avoid this battery and any lipo battery that you can't use a balance charger on.Working with Customer service now will update review after.

I bought this two months ago and it won't even hold a charge. It is completely dead. Of course, the return window closed at 30 days, so I am stuck with it. Look at a different brand.
