Motor current refers to the electrical current required by a motor to produce mechanical power. The amount of current drawn by an electric motor is influenced by various factors including its power rating, the voltage at which it operates, and its efficiency and power factor.
Batteries measure their capacity in milliamp hours, mAh. This states how many hours the battery can supply 1 mA of current, or how many mA of current it can supply for one hour. The current draw depends on the motor, for this, we can refer to the datasheets found on the product pages.
