So now that the motor is finally spinning in the right direction, the bike is nearly finished, and I took it out for a test ride. Unfortunately, it keeps shutting down. There are 2 types of different shutdowns: either the controller just cuts power but stays on, or everything shuts down. In the second scenario powering it on again shows half a second of display and they turns off again. After half a min or so it can be switched on normally... until the shutdown happens again. Seems to happen past 800w - not sure how correct display reading is though. Interestingly, when I pedal for a while with the system turned off, I cannot switch it on immediately. (same behaviour: display switches on briefly and than goes off again) Could it be some over voltage protection issues ?
System is:
- rh212 dd hub motor
- kt s12s controller + kt lcd3 display
- 14s battery (charge level is 50% during test) with 60A jbd bms.
Besides some wiring issues, I think either its the jbd bms wrongly configured, or the kt controller also wrongly configured - or both. I've beeing playing around with c parameters of the controller without success so far, and I'd hate to take the battery apart to check the bms, but will probably have to do it - unless someone comes up with an alternative explanation
Thanks for your help!
