The heatsink it is not a point, I drove for 75 miles with no problem, I did overload and system have not a chance to minimalize current, I have put wrong gear to see what happend and I know that I can't give car to my wife or other man. If only PWM could stop as quick as possible mosfets could get more chance to survive.
Other people experiance - Duncan, Adam who blown up mosfets proved that system is not quick enough when temperature is too high and they haven't got another chance to put bigger heatsink- in my opinion.
Paul, is it problem to put new temperature command or possible to overtemperature start quicker 65 C and limit motor amps i 2 steps half and 0at 75? I wish to have controll this parametrs.
