The power rating of the resistor is dependent on how much current the motor
draws during operation. There's usually a spike in the current when the motor
is first turned on, because it has to overcome inertia to start moving. But
this is the resistor in the charger, correct? If so, it might not even be
connected to the motor, and more likely is some sort of current limiting
resistor to control the charge rate of the battery.
