Best stored at refrigerator, NOT fewer temps. Best I can do is 55F. Store at 50% charge. 46.8V.changeissimple wrote: ↑Dec 12, 2017 12:43 pmI put my bike in the basement for the winter just last week because of the snow and ice here in Boston. Wondering if anyone has a recommendation for maintaining the battery until spring. It is a 48v 26.1ah panasonic 13650 lithium ion pack. I have a 4amp charger. Should I charge it once a week, one a month? should I run the motor and drain the battery periodically? I'd love help on this issue. Maybe there is thread on maintaining the battery for a few months - love some help/recommendations.
