The optional external battery pack can be connected to a Night Vision Devices BNVD equipped with an external power port in order to extend the operating life of the system.

The optional external battery pack will only work with our Night Vision Devices manufactured binoculars with an external power port. It is not compatible with our PVS-14, PVS-7, or any non-NVD brand night vision systems. To ensure compatibility, when purchasing a Night Vision Devices BNVD be sure to choose the external power port add-on.

The battery pack is powered by either 3 AA 1.5 Vdc Alkaline batteries or 3 AA 1.8 Vdc Lithium batteries, providing an additional 50+ or 100+ operating hours respectively. The battery pack is 2.7 x 0.9 x 2.5 inches (L x W x H) with a cord length of approximately 24 inches and weighs approximately 72 grams without batteries.
