Abstract: A battery pack including a housing defining an aperture, a first battery cell within the housing, a second battery cell within the housing, and a switch. The first battery cell is electrically connected to a first terminal. The second battery cell is electrically connected to a second terminal. The switch is configured to be in a first position and a second position. The switch includes a user-interface, that may extend through the aperture, and a plate, located within the housing. The plate includes a conductive portion and a non-conductive portion. The conductive portion is configured to electrically connect the first terminal to the second terminal when the switch is in the first position. The non-conductive portion is configured to galvanically isolate the first terminal from the second terminal when the switch is in the second position.

Abstract: A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the outer housing, and a drive unit positioned in the drive unit support portion, the drive unit including an output member. The power tool also includes a power screw mechanism with a nut fixed relative to the outer housing and a screw coupled for co-rotation with the output member and axially movable relative to the output member. The screw is in threaded engagement with the nut such that the screw moves axially in response to rotation of the screw relative to the nut. The power tool also includes a working assembly coupled to the inner housing for movement in response to axial movement of the screw.

Abstract: A battery pack and a method of assembling a battery pack. The battery pack may include an outer housing; a cell module supportable by the outer housing, the cell module including a module housing, a plurality of battery cells supported by the module housing, the battery cells having an energy of at least about 60 Watt-hours, a controller operable to control an operation of the battery pack, a conductive strap electrically connected to at least one of the battery cells, a weld strap connected between the controller and the conductive strap, and a terminal electrically connected to the battery cells and operable to connect the battery cells to an electrical device for power transfer; and a vapor-deposited, hydrophobic nano coating applied to at least a portion of the cell module.
