Power tool system having a battery pack

Abstract

The power tool system includes a power tool device and a battery pack that has battery cells organized in an arrangement that may improve the usability of the power tool device. The power tool device can slidably engage with the battery pack along a sliding axis extending in a longitudinal direction. The power tool device can operate a tool that may rotate about a rotation axis that extends in the longitudinal direction. The power tool device includes a handle having a centerline axis that passes through a surface of the handle and extends in the longitudinal direction. The battery cells have axes that extend in the longitudinal direction to align with the centerline, rotation, and/or sliding axes. The battery cells are disposed in a nested arrangement so that the space occupied by the battery pack may be reduced.
