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.

Abstract: A portable power supply including a housing, at least one battery cell, a charger, and an attachment. The housing defines a cavity. The housing includes an upper portion, a lower portion, a plurality of air inlets defined in the lower portion, and a plurality of air outlets defined in the upper portion. The plurality of air inlets is in fluid communication with the cavity. The plurality of air outlets is in fluid communication with the cavity. The at least one battery cell is disposed in the cavity. The charger is electrically coupled with the battery cell. The attachment is coupled to the upper portion. The attachment is configured to at least partially cover each of the air outlets such that airflow exiting the air outlets travels a circuitous path.

Abstract: An electrical device capable of emitting or absorbs energy relative a surrounding environment. The electrical device includes a housing, an interior volume defined in the housing, an energy sensor at least partially exposed to the surrounding environment, a first material having a first absorptivity, and a second material having a second absorptivity lower than the first absorptivity. The first material is nearer to the surrounding environment than the second material is at an energy sensor reading below a threshold energy range, and the first material is farther from the surrounding environment than the second material is at an energy sensor reading above the threshold energy range.
