The number of FETs dictate the amount of current (AMPS) that the controller can handle. The Mamba Max and the Monster Max are similar in peak amp handling capability, but because the Monster has a large heat sink and fan and more FETs, it's continuous amp capability is a little higher.

The Monster is also capable of double the voltage of the Mamba Max, which doubles the power handling capability.

ALSO, the FETs are better today than when we designed the Mamba Max -- so the current version of the Mamba Max can handle more power than the original. (the number of FETs is a bit of an overkill on the Mamba Max.)
