BMS Shuts down when motor tries to spin after getting ATR firmware

I just installed the latest ATR firmware on my Ubox. I used the 75_300_R2 firmware becuase that’s what it says on their website to use.

With this new firmware, any time I try and calibrate the motor, or spin it in any way, the BMS seems to shut off it’s output.

Did I do something wrong?

I have just realized that there is a UBOX_SINGLE and UBOX_100_SINGLE folder in the zip… did I just fry my Ubox?

I uploaded the correct firmware and everything works now. I am very lucky. Don’t do what I did.


Which BMS are you using?
