Abstract: A battery pack for a motor-driven appliance comprises a battery including a plurality of cells, a cell discharge unit that discharges each cell individually, a voltage detection unit that detects each cell voltage, a target cell determination unit, and a discharge control unit. When at least one cell having the cell voltage equal to or smaller than a specified threshold is present, the cell voltage that is the smallest among them is set as a smallest cell voltage, and when at least one other cell having the cell voltage larger than the smallest cell voltage by a defined value or more or having the cell voltage larger than the threshold by the defined value or more is present, the target cell determination unit determines the at least one cell as a target cell, and the discharge control unit causes the target cell to be discharged by the cell discharge unit.
