A tool system with a battery pack and a device that is configured to be selectively coupled to the battery pack. The battery pack has first, second and third pack terminals. The device has a battery mount with a body that defines a well and first and second device terminals. The body defines a well into which the battery pack is removably received. The first and second device terminals extend outwardly from a proximal portion of the battery mount and engage the first and second pack terminals when the battery pack is fully inserted into the well. At least one of the first and second pack terminals and the first and second device terminals is a male terminal that is received into a corresponding one of the first and second pack terminals and the first and second device terminals. A longitudinal axis of each of the first, second and third pack terminals is arranged parallel to a longitudinal axis of the battery pack.
