Display problem? DMHC TC480

[2nd2none]

Hi all,

I'm new to the forum and new to ebikes so please be gentle.

My ebike has a Bafang 250w motor, DMHC TC480 controller and display. For some reason the battery indicator is blinking on one bar and the bike does not function. I've swapped out the controller and battery and still no luck. I know the motor works as I've connected it to another ebike and the battery is reading 41v.

Problem is I'm unable to easily source another DMHC TC480 display. I know it uses UART comms protocol with 6 pins. If I find another UART 6pin display will it be interchangeable?

Else does anyone know why I'm getting this behaviour?

Thanks all

You get it fixed & find a place to by the LCD.

Hi 2nd2none,,
I wonder if you've solved your issue as I've same behavior on a Rich-bit TOP730 48 volt, with battery full charged.
i wonder if a wiring diagram is available anywhere
