ABSTRACT:
A battery pack device which can be removably attached to a SPH-4 helmet and used to power an ANVIS night vision goggle device which is mounted on the helmet. The battery pack device includes a battery pack assembly with a bent-shaped housing that enables the battery pack assembly to conform to the shape of the helmet. The housing of the battery pack assembly is adapted to hold only two replaceable AA battery sets to minimize the weight of the battery pack device. The battery pack assembly also includes electrical circuitry for selecting one of the two battery sets to power the night vision device. A support assembly adapted to be permanently fastened to the helmet is provided for removably attaching the battery pack assembly to the rear of the helmet.
