I have a REC BMS connected to my quattros. My batteries are 16S li-ion. I was aware that the quattros had a maximum voltage of 66V - which is close enough to my battery 90% charge of 66.9V (my set limit).
However, the voltage only sits around 64V - less than 65% capacity.
The BMS is reporting a Charge Current Limit of 92.9A and max charge voltage of 66.9V to the Venus when the charge current drops to 0A at 64V.
How do I get that extra 2V of charge?
