Mamba Max on 4s A123 cells?

I ran 4s A123 with the internal bec, a fan and 4800 medusa motor with no issues. Before that I ran 6S A123 with the external bec and fan.

On the MM? If so, did you feel the BEC circuit? I guarantee it would have been hot hot hot. It probably ran fine, but do you realize the BEC circuit is on the same PCB as the brains circuit, and that PCB is totally enclosed with no cooling except where the heat can make its way through the traces and then to the heatsink? I personally would not want all that heat next to logic circuits, but that's just me. Excessive heat is a component killer, or at least shortens component life.
