I've done an experiment to see how current thirsty the motors are..... by putting a 25amp power supply on each drive motor and then pushing down on the robot so it does a burn out (on the kitchen floor lol). The motors defo had more to give when being limited to 25 amps each, so a controller capable of 40 amp peaks should do the job without limiting the machines acceleration or pushing power much. The XXL is a very useful size, i'd really struggle to fit a 25A sabertooth in.

An XL/XXL upgraded to at least XXL spec sounds like the perfect solution.
