well i tried to tell people, any time you disconnected the cells and balance lead, the BMS will show PF and SS, PF is permanent fail and SS is a hardware issue, and of coarse i get crap for saying that, because they will say "i did it and it was fine" but working with EV2300 and TRB2300 for the past year, ive learned alot, so 1. battery has to be "reset," 2. you could try to look on board for RES and GND and take tiny wire or tweezers and touch the 2 dots and count to 5, and you might get away with a hard reset
it might work if you have a battery with NO ERRORS, but error wont go away just because you change cells, BUT why would you GUT a good battery
also FYI check every cell all 12 to make sure they are 3.9 minimum, remember its 12 cells to make 6S pack, all it takes is 1 cell off and BMS goes into "SS"
and on the MAH i would try to fly (once battery is in normal state) takes about 3 fly and charge the re-calibrate Most DJI batteries......hope that helps
