How to choose a motor battery

In any electric motor application, the target equipment performance dictates the required motor power. The rated power of the motor is calculated from the combination of speed, torque, and duty cycle of the application that in turn establishes the critical voltage, current, and capacity requirements of the battery. One motor parameter that affects the performance of battery-powered applications is efficiency. Maximizing motor efficiency helps minimize required power capacity — in turn. One essential criterion in battery selection is ensuring the battery will satisfy the motor's voltage and current requirements when fully charged as well as continue to meet those requirements.
