12V 100Ah LiFePO4 Deep Cycles Lithium Battery with 100A BMS, 4000+ Cycles Rechargeable Battery for Marine, RV, Off-Grid Solar, Home Backup Power, Trolling Motors, Boat etc.

I'll give this a 3 star because the little voltage meter (which is pretty useful) was DOA. I popped it out of the battery case, and the module looks physically fine. So I'm guessing that they just had a bad one, and didn't test it after snapping it into the battery. Otherwise the battery is great. It's a good portable size for my telescope, or just as a backup when I need so power on the go.Update 4-30-2025: The company sent me a replacement voltmeter and were really accomodating about it. They stand behind their products. I ultimately found that it wasn't the voltmeter, but a severed connection. You can just pop the top off of the battery and reconnect this and everything is fine. I've bumped them up to 5 stars because of their good faith!

Great battery at an affordable price. I use it for an aerator on a portable bait tank and it holds up for multiple all day fishing trips without losing charge.

This battery is very dependable and the built in meter is awesome too. I wouldn't run a trolling motor from it, the current draw will melt the terminals. But for running anything low volt, low amp, this thing will last a long time

these babys really make my battery scooter go ,love em

This is decently built, it feels like even if i drop it, nothing will break except what it hit. its a nice small package to and the weight is not bad, 6 lbs is lighter then alot of gaming laptops alone. also the fact it comes with a bms and a volt meter/battery monitor for the price is actually a decent deal. though i do have a few complaints. the volt meter is off by around .2 volts and a little inconsistent with each battery, i got this one for review then bought 3 so i have 4 to compare it to, some are off by .1 and some are off by .2. the next complaint is the terminals are small, wish they add something bigger or have an adapter of sorts so i can use bigger lugs on this battery. the last complaint is their advertisement, dont call it a 40a bms when it can only reach 20a continuous, its 40a burst for a few seconds. its misleading to call it so so please change that. other then that stuff its a good buy.p.s. it also comes with a decent warranty of 3 years so its pretty good. not the best, but definitely better then companies that do a few months to a year warranty.

This battery has been fantastic for my DIY setup, and the built-in digital charge display is a game-changer. Knowing the exact charge percentage at a glance makes managing my system much easier. I have it connected to a solar panel and a timing system, and so far, it has performed flawlessly.It’s easy to use, charges efficiently, and provides reliable power. I’m looking forward to seeing how it holds up over many power cycles with solar. If anything changes over time, I’ll update my review—but for now, it’s working perfectly. Highly recommended for DIY power setups!

Battery saying 100% and 13v but no power coming out wouldn't recommend buying these

Pretty nice batteries.
