Hello community, I have a CHINS battery (12.8V 100AH) with LiFePo4 cells. The battery pack contains four pararelled pairs strung in series to create the overall battery specs. The first pair of pouches seem to be not holding a charge. I have moved the pack about the bank with no improvement. I have top balanced this pack on several attempts. I have removed the pair and attempted to charge them independently but they fail direct charge. 1) I need to know what the amp amount of pair is. 2) I am assuming these are A123 pouches and need to know who carries these in the US. The only markings I could find on the pouch cells are: LY26F1316524508066
