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.
