I built 2 X 272amp 12v Lithium battery packs using the Lishen 4 X 3.2v cells and an Overkill BMS. All balanced, charged up and good.
When I look at the BMS, at +/-3400mva charge per cell (13.7v for the pack) the amp capacity is only showing 85%. This cant be correct. To get 100% ie 272amp hours, the battery would need to be at 14.6v charge!
Im looking for the Mva setting for full charge, 80%, 60%, 40%, 20%??
To get the pack up and running, I just went with the Overkill default settings - maybe this is throwing out the numbers.
Ive asked Lishen and they send me the charging current chart - not helpful! I know max cell charge voltage is 3.65v. Their data sheet says nominal voltage is 3.2v.
I know others have built packs using the Lishen cells, so info to help? TIA
