Abstract: A power tool system includes a hand-held power tool having a housing with a battery pack interface, an electrically-driven device and a first connector. A battery pack is detachably attached to the battery pack interface and supplies current to the electrically-driven device. An adapter has a second connector physically and electrically connected with the first connector in a detachable manner. The adapter receives power from the battery pack via the hand-held power tool and provides at least one additional electrical function to the hand-held power tool or performs at least one additional electrical function that the hand-held power tool is not otherwise capable of performing. Further, the adapter is at least partially disposed in a space defined in part by the housing and in part by the battery pack when the housing and battery pack are attached to each other.

Abstract: A battery pack of an electric power tool comprises ten lithium-ion cells. The ten lithium-ion cells are connected in series. Each lithium-ion cell has a diameter equal to or less than 18 millimeters, a length equal to or less than 65 millimeters, and an internal resistance equal to or less than 30 milliohms. Because the battery pack has a high voltage in operation and is therefore able to supply large current, the battery pack is preferably configured incapable of being used in a conventional electric power tool that cannot operate under such a large current.
