12V 300Ah LiFePO4 Lithium Battery, Built-in 200A BMS with 6000+ Deep Cycles Rechargeable 3840Wh Lithium Battery for RV Solar Marine Solar Panel Camping

Great quality batteries! They shipped fast and arrived sooner than anticipated, which was awesome. I had a few questions and the seller answered quick and was super helpful. 10/10 service. Great value for the price! Batteries work as they should, no complaints.

I used one of the 100 Ah 12.8 V models to build an off-grid solar power rig. I have not load tested to know if it truly hits the 100 Ah level, but it is easily exceeding my current needs. It will accept as much power as my charge controller and panels can dish out (about 30-35 amps) until it fills, so it charges quite well and quickly. I've been able to leave my inverter on 24/7 without any concern about the drain. They included two sets of post bolts in the package, so you have spares if you damage or drop one. Post bolt caps are also included. They appear to be either 8mm or 5/8", not sure, haven't checked which, but they fit nicely into the commonly-used ring terminals. I was able to connect it with a battery post fuse to a DC fuse block to connect it to my miscellaneous DC loads. Going to be adding more loads in the coming weeks, including lighting, computer networking equipment and two-way radios and may update this as the demands for after-hours power grows.

The first battery would not accept a charge, but when I contacted customer service, they promptly sent me a replacement battery which works perfectly. Very impressed with customer service.

No good Contact the seller seller tells me first I need to use a 2500 W inverter now he’s telling me I need to use a 2000 W inverter when the battery does not hold charge Product is no good does not hold charge don’t waste your money on this product

Weighs roughly 60 Pounds. It works great. The Power is amazing and the quality is amazing. I’m running 200 Watts Solar with a small house fan and charging my phone. The size is a little bigger than I imagined but that’s my fault. I will be ordering at least one more 300 Amp battery. I’m definitely positive this will help achieve what I’m going to accomplish.

This battery works like magic with my solar panels! Great quality at a sweet price, and super fast delivery. Once installed, it's been absolutely killer – rock-solid 12.8V output, packs a serious 100Ah punch, and handles peak demand like a champ. My system runs smooth as butter! What's even better is that this battery is so small and lightweight that it's practically universal - for home use, caravan power, boat equipment, whatever the occasion!

This battery works Perfect for a battery upgrade in the RV running a 2000 W inverter. I’ve charged it approximately 7 times with now no issues. Long lasting battery. I’m using a 60 amp smart converter charger.

So far this battery has performed as promised.
