A battery pack for powering a battery powered tool may include a housing, a plurality of cells and an electrical connection assembly. The housing may include a sidewall assembly configured to correspond to respective sidewalls of a battery compartment defined at a portion of the battery powered tool
A battery pack for powering a battery powered tool may include a housing, a plurality of cells and an electrical connection assembly. The housing may include a sidewall assembly configured to correspond to respective sidewalls of a battery compartment defined at a portion of the battery powered tool to facilitate insertion of the battery pack into the battery compartment. The sidewall assembly may form an enclosure around the plurality of cells on all sides substantially parallel to the direction of insertion. The electrical connection assembly may be disposed at a portion of the sidewall assembly to communicate the combined output to a connector disposed at a corresponding sidewall of the battery compartment. The electrical connection assembly may be arranged to engage the connector responsive to movement of the battery pack in a direction substantially parallel to the direction of insertion of the battery pack into the battery compartment.
