they can deliver a max of 175 amp burst but the motor will never draw that much current. probalby draws no more than 100amps at the most. the motor only ask for what it needs and the esc gives it. only time you get high am spikes is under initial acceleration and i think when you stab the throttle but once you get moving the amps drop down a bit just to keep the truck moving. probably can have some one else explain better.
