Hi folks,
I just built my first pack with CATL 310AH cells. I first top balanced them in parallel. I then connected them to the BMS and drained them. I then charged them with the BMS connected and when done, all the cells were at the same level. Overnight they have changed quite a bit especially the 1 cell. Does this indicate a bad cell?
