Hello ESFMs,
I have got a overvoltage protection error on a new build. Do I need to buy another controller? If so, what do I have to look out for?
Here are the facts:
Bought this kit:
Motor: 1000W geared rear hub motor
Controller: Rated voltage 48V, Limit current 28A, Nominal current 14A, rated power 1000W
Display: XT-LCD W108

And bought this battery:
Hailong 52V14ah, Continuos discharge current 25A-30A, Peak discharge current 45-60A
https://www.aliexpress.com/item/Hot-sale-48V10-4Ah-B-05-ebike-battery/32690721323.html
More info:
Display shows continuously overvoltage protection error (Er07) after turning on the battery.
When I have the motor disconnected the display only shows this error. With motor connected I first get another error (Er30) and after some seconds with the controller getting warmer I get the overvoltage protection error. I cant find the Er30 in the display manual and there is not much information about it.
I opened the controller and found that there are some copper strings from the power supply cables disconnected (see attached photo) Could this cause malfunction?
Thank you in advance for any advice!
Robert
