Better batteries than a matched IB4200 pack? I know there's lipo, but you shouldn't need that to eliminate cogging. I think it may just be a loose wire between the ESC and motor.
At any rate, when the truck was running properly, it wasn't cogging. What is the anti-squat setting? Big spacers in rear?
IB4200's are not capable of supplying the needed amps to fully run a Mamba Max system depending on the esc settings period. THe mamba Max can draw 100 amps continous IB's cant even come close to that.
