Not true, as those wires are only carrying the signal to turn the FETs on. From that board, they go right to the motor, and I can also use thicker wires to make that connection as well, further cutting losses. Cutting power losses is only a beneficial side effect of what I am trying to achieve. I want to be able to run
any motor I choose. I want to achieve that goal wihout having to build big towers of FETs that won't easily fit into the XMod chassis.

...and you have found this information where? I'm assuming you mean 10V @ 2.9A, because AH is a rating of battery capacity, not current capacity. 10V @ 2.9A is 29W. I highly doubt that the mystery manufacturer has come out with chips that can handle 10x the current without adding better forms of heat dissipation.
