  • Patent number: 9680325
    Abstract: An electrical combination. The electrical combination comprises a battery pack configured to be interfaced with a hand held power tool, a control component, and a semiconducting switch. The transfer of power from the battery pack to the hand held power tool is controlled by the control component and the switch based on one of a battery pack state of charge and a respective state of charge of one of a plurality of battery cells. A discharge current of the battery pack is regulated based on the switch being controlled into one of a first state and a second state by the control component to selectively enable the transfer power from the plurality of battery cells to the hand held power tool.

  • Patent number: 9673648
    Abstract: A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell.
