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

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!

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.

First off, the product is awesome. I've been using it in my RV for about 10 days and it works great.Second, the seller has provided outstanding support. Both batteries were damaged in shipping. I received a replacement within a few days. Buy with confidence.

Installed the 2 batteries in my R.V., it’s running a 55 watt bodega 12 volt fridge and gets discharged after about 30 hours, should last for 10 days, no help from the seller and no refunds. Hoping it’s a bad batch bought it with a warranty.

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.

Even though the price has recently increased this is a very good value. Battery is well made and appears to live up to its specifications. I replaced two 80 ah lead acid batteries on my camper. This works sooo much better and so much lighter. Well worth the money!!
