If you get rid of the gear-up you can increase the motor voltage to get the same wheel speed at a faster motor speed which puts the motors at a much happier operating point.

Motors don't like to go slow. They want to go fast.

What do you mean by running them at a different voltage? As I understand it, the current changes when more or less power is given to the motor, not the voltage.

Also, changing the ratio to be greater will make the motors run faster, not slower, to run the outputs at the same speed. I'm not quite sure why changing the gearing would change the motor speed. As I understand it, it would just make the belts spin slower. This would give them more torque, but the motors are overheating even without feeding balls through.
