I'm getting a flashing 30 on the middle display, and the left display shows an empty battery. But the battery indicator shows full charge, and it has 52v on the battery terminals.

I went through the Rad power diagnostic process of unplugging all the connections, and reconnecting them, then disconnected everything except the battery, controller and displays. No matter what it still has error 30 and low battery indicator on the handlebar.

Is that a new controller? Should I send 170€ on a replacement, or would it be more reliable with an after market controller and display?

Any insight is much appreciated
