I was charging my EM3EV Samsung Q cell 52V super shark for a ride this morning... normal charge, to 58.8V at 4 amps... and sometime after it went into tapering mode at 58.8v and 1.5-2 amps it stopped charging and said "volts too high". I took it off the charger and put it on the bike and it was reading 56.2V. Anyway, I went for my ride and had plenty of juice for what I had planned. Finished up reading 50.5V on the bike display. Anyone else seen this issue or have any advice? Is this possibly a BMS issue? Or maybe an unbalanced cell?? I guess I'll try a charge to 85% first and see how it handles that.
