I would guess that it's a cell or wiring issue.It still doesn't work that well in my case.
Yesterday cell 11 hit OVP. Today it was cell 9/7 that was staying higher.
As such I reduce to 54.8V until I'll have some "closed-loop" control algorithm to actively lower/increase the voltage based on the highest/lowest measured cell voltage.
Why the hell one JK BMS always measures approx. 0.7V more than the other (almost 40-50mV/cell) ... I don't know.
Or possibly a faulty BMS.
My cells are balanced to within 0.003v delta at 3.5v , every full charge.
No closed loop crap here.
