Battery repair
I have a 3 yr old 48v 17 ah down tube battery I got with a Bafang bbshd kit with a problem w the on/off switch. A half a year ago the rocker on/off switch was inconsistent turning on so I left it on all the time then it started cutting out when hitting slight bumps. I’m usimg a cheap spare battery I got from Amazon. Curious if other folks have had similar problems. I ride off road most of the time and assumed the battery can take the vibration. I’m hoping this might be something I can fix myself once I have enough understanding of the problem. I figure shipping and repair costs would get me 25%+ to a new battery so gathering info now. While I ride off road I’m 67 and not going off jumps, 10-15 mph is my speed.
