Lithium full charge issue.
I have 2 X 280amp lithiums. 9 months old. Each cell is 3.65 max volt. So 14.6v for each pack.
Connected to Victron Multi. The Victron is set to charge to 14.55v.
Overkill BMS. Set to 3.65v max charge per Cell and 14.55 for pack. Delta set at .15
Problem. Each cell maxes out at about 3.4v charge, 13.6v for the pack. Each pack is identical.
Why can’t I get it to go full charge to +/- 14.55??
