Simply speaking, Watts = Voltage x Amps So, a 500W controller can handle a different amount of amps depending on the voltage being used. Scooter controllers typically come in 12V, 24V and 36V models and we typically use 24V models so that we can power them from two large 12V batteries in series. Therefore, at 24V a 500W controller can handle approx 20A of continuous current. Fortunately, the scooter world has it's act together and they almost always rate motors and controllers the same way. So, if you have 300W 24V M01 motor, then a 350W or 500W 24V controller should have no problem driving that motor in normal operation. The controller will start to overheat if the motor is locked up for an extended period of time and some scooter controllers have a built-in failsafe that simply cuts all power in that case. Some more expensive ESCs limit power in such cases to allow the vehicle to operate at a reduced performance level until the overload condition has ended at which point it goes back to full power.
