because i run several times into overvoltage cutoff and have no other brakes than my motors on electric boards, i tried to make a circuit to solve this problem.
It should switch a dump load in parallel to my battery and ''v''esc whenever the voltage in said lines goes above a set value 0,5 volts less than cutoff is set in vesc), and switch it back off when voltage is aprox. (depends a bit on set voltage) 0.5v lower than the set point.
here is my circuit:

how big should the dump load be? the same size as i set my battery regen current? and any ideas what i could use, these resistors are big...
please try to keep it simple, i'm relatively new to this^^
got a lot of help here -> just in case someone wants to see my noobish errors
