12V 200Ah Lithium Battery,5000+ Deep Cycle LiFePO4 Battery

I gave these batteries a 5 because they are far superior to the agm batteries I was using. They take a learning curve because they are not agms and I have not used any other lifepo products to compare them to but I am quite pleased with the results. I have bought 12 and will be buying 4 more for a total of 19.2k of power which will run all my house. You need to keep a fresh power source to start them back up should they drain but it only takes a tap and they are back up and running. All in all I'm very happy with them.

I upgraded to a 24 V Trolling motor and expected to need more frequent charges. With these Lithium Batteries they keep going long after I would expect to need a full charge

This is a very expensive battery. There are no returns. You cannot return if it is defective. Mine was. I have spent hours texting different 24V chargers, mppts, inverters, and nothing charges the battery, nothing is able to pull power from it. It reads 25V, but after 8 hours of time wasted on this defective battery unfortunately it's looking like a total loss. I've contacted the seller since you cannot return it outright, we'll see if they even reply (or exist)

Hubby bought for our travel trailer and says they are the most amazing batteries he’s ever owned.

Great battles for the the price. Supplies 400ah to my 3000watt inverter.

why is it when I click on the 2,3,4 pack the price seems to be more expensive than the 199 per cell? great LiFepo4 cells one has served me well for 6 months now. love my off grid power now to buy more in parellel!

I bought two of these in Jun of 2022. I didn't measure the voltage before installing the batteries into my then new battery bank. About two weeks ago I measured all the batteries i the battery bank because it just wasn't lasting as long as I thing it should. Both of these things were low, one almost nothing and the other at 10,7 volts. I send two messages to the manufacture and heard nothing in return. I popped the top off and found one didn't have the BMS installed correctly. I was able to charge each cell and install the BMS correctly and the battery is now working correctly. The second battery that measured 10.7 vdc had a damaged sensor connector, it was broken and crushed. I ordered and got a new BMS and installed it after getting all the cells up to the proper voltage. Shame on me for not checking the batteries when they arrived. They sat there for two years doing nothing. Shame on BtrPower for such poor quality control. No, I do not recommend these batteries, buy anything else then check them before installing. Zero stars if I could for bad product and not answering emails. No customer service.

easy to connnect. Fast shipping. So far my batteries are doing great. I bought these batteries for my home solar system. Easy to connnect and work well. and better customer service. Had a issue but the seller more than adequately solve my problem. In fact they went over and above to make me happy.
