Abstract: A battery pack for use with a power tool and including a housing having an internal cavity in which one or more battery cells are supported. The housing has a set of openings. A printed circuit board is supported within the housing and in electrical communication with the battery cells. Battery pack contacts are coupled to and in electrical communication with the printed circuit board. A terminal block is supported by the printed circuit board and encloses the battery pack contacts. Each of the battery pack contacts are accessible through one of the set of openings in the housing and the terminal block. A first gasket is positioned between a first wall of the terminal block and the housing and a second gasket is positioned between a second wall of the terminal block and the printed circuit board.
