Abstract: A battery pack and a method of inhibiting failure of a battery pack. The battery pack may generally include a housing; a battery cell supported in the housing and electrically connectable to an electrical device, power being transferrable between the battery cell and the electrical device; a resistor supported in the housing and operable to receive current from the battery cell; and an electronic processor configured to detect a failure condition of the battery pack, and, in response to detecting the failure condition of the battery pack, cause the battery cell to discharge through the resistor.

Abstract: The present invention relates to a battery pack including a housing, a latch mechanism, a printed circuit board connected to electrical terminals, and an internal frame. The housing includes a first and second portion. The first portion includes openings that receive the latch mechanism and openings that receive the terminals. The battery pack also includes a latch cover that protects against water infiltrating between the openings and the latch mechanism, and a terminal cover that protects against water infiltrating between the first housing portion and the terminals. Water that enters the battery pack is directed to the bottom of the battery pack. The water is then drained through openings in the lower housing portion. The internal frame includes openings that secure batteries within the lower housing portion with the help of wedges that are positioned in between adjacent rows of batteries.
