I will speak with guy who made a tests on ESC to check Ezrun 150A, does energy recuperation braking works there?
Ok that guy made a test and still No true regen brakes in ezrun 150.
He made test device/stand. In one side motor spinning other motor which was he tried to brake. Yeah, he noticed regen spikes (Voltage and negativ current) but those spikes are realy short, impulse lenght was 0.002s-0.007s so no true regeneration there, just some spikes thats all.
Seems ezrun 80a make same spikes
