We noticed that many friends are talking about GRADE A and GRADE B LiFePO4 CELLS. As a professional battery company established in China for 18 years, We can responsibly tell my friends here that the easiest way to distinguish between GRADE A and Type B batteries is that GRADE A cells has the original manufacturer's test report. The data should include the internal resistance, voltage, capacity, and product code of each cell (usually the same as the information on the QR code). Without these, 99% maybe GRADE B batteries cells.
As another way, the current sales price of Grade A cells, the mainstream lithium iron phosphate manufacturer in China, is US $0.12-$0.15 per Wh. Please note that this price does not include any international transportation and other expenses. If your purchase price is lower than this price, you are sure that you are not buying grade A cells.
