I found that the voltage of a certain group of my battery pack (16s5p) is always lower than the other groups. When the pack is fully charged and balanced by the BMS, that group will be the same as the others. But after using the pack, that group will be lower than the others. The difference is about 0.07V. I understand that this may be because that group has a lower capacity than the others. Will that also because the BMS only draws current from that group?
I am planning to charge only that group manually so that its voltage matches with the others. Do I need to unplug the BMS before doing the manual charging to that group?
