for EP racing, heat management is everything, not many people know this, but you can use a voltage booster to keep your low amp electronics running at a constant voltage. the Team Powers Fan booster does exactly that. with some smart circuitry in a small package, the fan booster keeps your fan working at a constant 8.4volts no matter how low your battery is. Yes thats right, constant, FULL power from start to end of race. Combine this booster with the Team Powers fan and the SuperStock Fan Shroud and you have an uncompromising cooling package that is lighter than most fan/shroud combos on the market today
