Hi, so I have a 60v 25ah lithium battery17s fully charges to 71.4v) and recently with the cold weather etc I left my stealth bomber in a outhouse where it is very cold, when I went out the other week I charged the battery when it was freezing and noticed the battery was on 66v just after a short ride when normaly the same distance at the same speed etc I have about 69-70v left I've done some testing today when charging the battery when it's room temp and its fully charging to 71.2v but when I take it off the charger it reads 71.1v what could this be and is it a major problem? Also it shows 71.1v through the actual charger port then shows 0v after about 30 seconds.
So I'm not sure If that's just the BMS or something but I didn't realise I shouldn't charge the battery when it's that cold until I looked online lol
I'm not a pro with these batteries so any help would be appreciated thanks.
