High Quality LiFePO4 cells
I purchased the 215 Ah 12V set of 4 cells. Shipping from China was as fast as could be expected and arrived a day early. Rachel was very helpful in providing a spec sheet and individual testing results on each cell I received. The included hardware was high quality. I did not purchase their BMS. These are high quality new Sinopoly prismatic cells. I have run my set through a full charge and discharge cycle, and confirmed the test she sent me on each individual cell. I was able to extract the full 215 Ah from the set without discharging any cell below 2.8 volts. They were well matched. At the price, I couldn't be happier!
