    any current, just put a heatsink on the big chip and fan cool it.
    All it should cost is about $7 for a heatsink and a fan.

    will a big passive heatsink work too? because dust on heatsinks can be very annoying and i live in an dusty environment.

    JRK will handle 30 amps continuous all day with 40-45 amp spikes with heatsink and cooling, at 12 v though
