what is this protector you're referring to? I thought your controller had burned out the first time due to too much reverse current from the motor when coasting downhill? or did you discover it was a separate issue with the motor wiring that cause the controller to burn out?Mattr567 wrote: ↑Thu Aug 01, 2019 10:15 pmI just replaced the controller as well as adding a 2nd battery and have been riding with no issues at the same settings. I did turn off kers after if that matters at all. I decided my issue was the motor wiring shorting out since I wasn't running a protector. Got that all sorted ofc.overdoser wrote: ↑Thu Aug 01, 2019 12:51 pmThanks everyone for all the useful info in this thread. The same thing happened to me and I'm not sure what was the cause. At the time when my controller burned out I was running custom firmware with ver 1.5.5 due to upgrading to pro dashboard and BMS 116 but I was on the stock m365 battery. I also had KERS turned on initially maybe for a couple rides but then changed it to off by setting the activation to 40 kmph.
For my power constant I never went below 38000 and KERS was always set to "weak." Speed limit was unlocked and I was averaging 22mph (35kmph). My ride on a local bike does have me go under and then up about 4-5 bridges and I weigh 185lbs. The stock motor struggling to get me up the incline after going under the road/bridge is what made me upgrade to a bird zero wheel.
After i burned out my stock m365 controller, I upgraded to a M365 pro controller using firmware 1.5.5 but using BMS 115 which is for the stock m365 battery. Now I'm on firmware 1.5.5 using gonkad365 from http://xiaoscooter.site/en/custom-xiaom ... re-builder. Seems like that is what is suggested for my specific setup (stock battery with pro display).
I also went back to my stock m365 motor until I can figure out what is safest setting to prevent burning out another controller with a bird zero motor. Could it have been due to the motor regenerating too much power going downhill while battery is fully charged even though I have KERS set to 40km and regen "weak?" Any advice would be greatly appreciated!
