Haibike hard seven 4.0 yamaha motor.
Second yamaha 500w battery purchased for longer rides was ok for 2 rides then showed error code 71 and wouldn't connect. Original battery is OK.
Shop where I bought battery exchanged it for another , same again 2 rides later with second battery showing error code 71 and not connecting . Original battery is fine so bike must be ok . Has anyone had similar issues and any ideas .
