摘要： In order to prevent a battery pack from being overly discharged during use in a power tool, a discharge voltage limit circuit is provided. The circuit disconnects the battery pack from the motor when the voltage of the battery pack falls below a predetermined level. However, the circuit is operable only when the main switch is OFF, that is, when no load is imposed on the motor.
