I know this is an old thrad but ive got a A2B ferber 2014, battery is loosing charge quickly. As I just got bike I dont know if this is cold or the battery. Ave 10 miles per charge on normal on hilly ground.
Any ideas please.
I'm getting very strange battey usage lately. Today It was zero degrees the bike was outside for a few hours, went back and 50% of charge was gone.
What sort of milage are others getting in the cold. I have a 36v and 8.8amp.
again how do i best check the stae of the battery?
