Right, but the constant barrage of amperage that is already there, due to running your motor, causes the FETs to get warm. Then when you subject your FETs to peak amperage (or at least something higher than normal), it blows your FETs. I'm looking in to when exactly peak amperage occurs - whether it's start up or whenever.
