We’re running pololu 30:1 motors with 60mm wheels. At the higher voltage we get a micromouse Drag race speed of about 2.2 seconds. (for 5.65 meters)
Current (9 volts) to 1 motor (stalled) = 1.1 amps Not stalled = 0.68 amps.
At the 5volt setting it’s about 0.23 amps.
No trouble so far Fingers crossed.
