L3Harris AN/PVS-31 Battery Pack

The L3Harris PVS-31 Battery Pack is a rugged and lightweight power solution made from glass-filled polymer, designed to extend the operational runtime of your night vision setup. Powered by four lithium AA batteries, this external pack delivers 50+ hours of continuous use and is compatible with the PVS-31A, BNVD-1531, and GPNVG (dovetail variant)—eliminating the need for onboard batteries.

This unit features dual built-in IR strobes for IFF and signaling, controlled via a toggle switch on the lower left side of the pack. Its contoured shape fits the curve of most helmets and attaches securely via hook Velcro, serving both as a power source and as an effective counterweight.

Included is a 25″ BNVD-style power cable with two right-angle connectors and a quick-detach plug compatible with Fischer connectors.

⚠️ Important: This cable is not compatible with LEMO connectors. Using it with such devices may result in improper function and can potentially void warranties.
