I have a generic OVERKILL style JBD BMS. it never charges evenly, pack 4 always hits 3.6 before the others get out of 3.3… so I decided to hook a 5a CV charger to the low cells.
sounded simple, however, I hit an issue. Cell 2 charges fine up to 3.6, cell 1 fine up to 3.6 cell 3… when charging it, cell 2 dives in voltage, and everything starts dropping to 3.3ish… and the pack goes all wonky.
