12V 200AH LiFePO4 Lithium Battery Pack 100A BMS for RV Marine Solar System Trolling Motor

It's definitely got some cranking amps. I'm sad I can't get another one, so expansion becomes harder. But as a stand alone off the grid battery it has some potential.

I ordered 4 200Ah batteries at $579.00 each. One of them arrived with a voltage of 0.24V. I sent a message to the company via Amazon email requesting a replacement. The company approved the return of the bad battery but did not provide a return shipping label. I left a message to Amazon stating that I felt I should not be held responsible for shipping charges to return a defective battery. Then I received a message from Eileen at the company saying I would not have to return the bad battery and a replacement battery was on the way.

At the 31st or 32nd day I realized that one of the other batteries registered 12.90V and would not take a charge. I thought "great the time has gone over the 30-day mark and I won't get any results". The battery would not run my 4000W inverter. I put it in parallel with a good battery and it still wouldn't run it. Then I connected one of the good batteries to the inverter and it worked fine. Thankfully, the company sent me a replacement battery after I explained the problem.

Unfortunately, that replacement battery registered 12.898V and would not take a charge. So, now I had 3 good batteries and 3 bad ones. Again, I notified the company of the problem and, again, they (Eileen) were quick to resolve it with a replacement.

Now, after 2 months I finally have the 4 good batteries I originally ordered. And 3 bad ones I have to figure out what to do with.

If you receive a battery like this 200Ah LifePo4 that I have been dealing with and the voltage is less then 13V, try to charge it right away. This battery will take a charge of 14+Volts. If it does not, I hope my information will help you to resolve the issue.

This company is one of the finest, most honest on the planet in my opinion.

The battery was everything I had hoped for, and the customer service was better than I imagined. They go the extra mile to assure the customer's needs are met. They were prompt and courteous. I highly recommend them.

We purchased one of these to test on our RV. It arrived in a reasonable amount of time but did not have 12v as we were only getting 8v. I contact seller to return it for refund. The seller returned my email same day and sent us a replacement. We got it really fast. Turns out the first one was damaged in transport. Overall, the seller went over and beyond to ensure we were happy and we are. We plan to purchase a few more to make a battery bank for a solar system on our RV. The battery is exactly as described and was much lighter than expected. It came with everything we need to ensure a good connection. We are very satisfied with the battery and the sellers customer service.
