My ebike with bafang bbs02 and 48v 14 ah battery started to shut down recently. It's a couple years old with 500 miles or so. If I wait a minute and cycle the battery's power, I can turn on my display and ride again. But it shuts off within seconds of riding.
I inspected the bike and found scorch marks and melted plastic around the connection on the battery bracket. So I paid a local shop $70 to install a connector that I supplied. Unfortunately I still have the same problem. The charge indicator on the battery shows a full charge, and it reads 52.4 volts on my multimeter.
How do I diagnose further? Could it be the controller in the motor?
