A battery pack for use in providing starting power for a starter motor of an internal combustion engine and to supply power to one or more auxiliary loads. The battery pack includes an outer housing that encloses a plurality of battery cells. A control unit is positioned within the outer housing and is connected to at least a starter switching element and an auxiliary switching element. The control unit controls the position of both the starter switching element and the auxiliary switching element to selectively connect the battery cells to the starter motor and the auxiliary loads. The battery pack further includes an ignition input terminal that is connected to the ignition circuit of the internal combustion engine such that the control unit can monitor the operational status of the internal combustion engine. The control unit can selectively ground the ignition coil of the ignition circuit to enable and/or terminate operation of the internal combustion engine.
