Hi All-- Ill be going away for four weeks--is this long enough to warrant leaving plugged in in storage mode or okay to just charge up in standard mode and unplug? If storage mode, I have two charging options--110/12A and 220/20A--is one better than the other? --Paul
I wouldn't leave it unplugged. If you get a stretch of hot weather the BMS might run down the battery trying to keep it cool. I'd leave it in Storage Mode plugged into a 240V outlet.
Plug it in. Either 110 or 220, whatever is most convenient. I'd probably do Storage Mode, but Standard Mode would also be fine. If you do Storage Mode, be sure to select Standard Mode the day before you drive it, so it can fully charge overnight (at 220 if possible).
