I have a electric bike that i hadn't used in a while . Its a 60v battery when i came to use it it did not work.
Plugged it into charge as i thought it was a flat battery and worked Ie wheel turns round. When I unplug it doesn't turn around I tested the battery and it shows its charged 72 v When I turn on the bike the voltage drops to 13 - 19 volts Turn the bike off again and it shoots back up . I have a spare battery and when that is connected bike works fine .
The bike is a old street legal moped 250 watts 48v That i was overvolting to make go faster .
If anyone has an idea for me id be very grateful
