The king kong is firmware upgradeable which is a nice feature when something unexpected is found. I have only tested the 100A esc, not the 200A. I've talked to hifei about adding in a current control feature but they aren't too interested in the bike market at the moment. Even so, my testing went well and the throttle is nice and smooth.
5. 200A continous(230A surge)
14. Programmable current limiting(very sensitive/standard/insensitive/disable)
17. Thermal Protection(100 centigrade)

i did some additional testing with my hv 100A controller
when i use the 100A controller the problem does not occur, very weird
i hope somebody can help me out!

All wired up to the 80-85 motor on the bench I thought I would see how it worked if I changed the pwm rate from 8kHz to 12kHz. The motor with no load ran roughly for 2 of 3 seconds, having trouble keeping sync. So I disconnected the battery and programmed the 8kHz mode back in.
But the damage was already done When I ran the motor up again, it rotated erratically for a couple of seconds then the 16 guage battery leads I was using, smoked up and melted
It would seem these controllers are perhaps not as robust as they look
CNCAddict wrote:You sure it's the ESC? If the small gauge input wires started smoking then it only means there was high current on the battery side which is not uncommon during the start sequence. It could be there are some problems with your motor or ESC/motor connection. Don't give up yet
