Very interesting Setup from Mega Motors

Actually this is not true at all... their numbers are correct.

Amp draw increases with voltage. Given the same motor, etc... more voltage always means more current.

The high voltage/low amp draw thing is due to using a different motor/gearing setup with the change in voltage.

This is how a system can operate on lower amp draw and still make the same power (watts). You use a much milder amp draw motor and just feed it more volts.
