Recently converted to EcoBattery. I have used for a few weeks without issue and now it has quit. When I flip between tow/run with it in reverse, the buzzer will make a quick buzz then nothing. The 12v in the dash is working and all connection are good. I have 52v at the motor. Not sure what to check next.

Have you bypassed the OBC?

The OBC controls the old charger and will lock out the motor controller if it doesn’t see charge cycles. It will run initially, but when the OBC decides it should shut off to protect a battery that hasn’t been charged is anybody’s guess. A few weeks is consistent, depending on use. Plenty of info on how to do the bypass.
