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.
