Four weeks ago I have built one of my sub-packs of 10 CALB 130Ah cells, connected them in series, and installed the Lithiumate BMS boards on them. Each cell measured between 3.26 and 3.27 V at that time.
Today I checked the voltage, and 9 cells are still at 3.27 V, however 1 cell is now at 3.20 V!
What happened? The cells are new, never been charged, never been discharged...
Can I just leave this pack as is, and will the initial charge of the fully assembled pack pull the lowest cell of this sub pack back up again to an equal level with the other cells? If not, what should I do?
