My vesc won’t break at high speeds (15-20+mph), but does around 10 or less. It’s running ackmaniac 3.10 firmware, but I doubt that’s the problem. I hooked it up to the console and got over voltage errors when braking. I have a single drive 190kv setup with a 12s lipo setup. Max volts is set to 57v.
I put Regen breaking at 1.5a, and it doesn’t over volt anymore, but braking is almost non existent at that point.
From what I’ve read, I don’t see why a 12s setup would ever go over 57 volts unless braking downhill. But it happens when bench testing and no load, seemingly regardless of battery levels (tested between 4.2-3.8v per cell).
Any ideas on how to fix this? Would adding capacitors help? I know they are used to negate voltage spikes. Battery wires aren’t more than a 3-4 inches, so I don’t think that would cause such huge voltage spikes. There aren’t any coils either. My mini remote seems to be working fine, so I don’t think it’s the remote either. Thoughts?
