I have an e-bike with the cyclone 3000 kit and a 20AH 52v lunacycle battery and after completing it I took it for a test ride for about 15 miles.
It worked great no problems.
The next day I went around a few blocks and all of the sudden the entire thing shut off.
I rode it home and checked the wiring, everything was okay. The engine was only warm to the touch. The battery was very hot. However the battery was only at a few volts even though it was just fully charged.
To be sure I unplugged the battery from the controller and remeasured the voltage and it was now at 45v.
After plugging it back into the controller it turned on and worked fine.
I took it out again and after only a few minutes it cut out again and after disconnecting an reconnecting the battery from the controller again it did work but this time it was showing a very low battery indication on the throttle.
After bringing it back home I measured it again and it was at only 1.2v when connected to the controller and 40v when disconnected.
I concluded that there was a short in the controller but today I plugged it back in again and it once again works fine. I only rode it through the yard for a few minutes at low speed but after checking the voltage it remained stable.
I'm not sure what sort of fault could cause this issue but I have to assume the issue is with the controller.
Does anyone have any input on this issue?
I don't want my battery turning into a bomb, it was pretty darn hot for a very long time after I stopped riding it. No surprise if it was shorted.
