The NVG Battery Power Cable is a helmet power lead designed for use with external battery packs and compatible night vision devices. This cable uses the standard 4-pin Fischer style connector seen on many dual-tube and panoramic goggles. It allows users to run external power from a helmet-mounted battery pack to their night vision device, reducing onboard battery weight and improving balance during extended use.
This cable is compatible with common night vision systems that support external power through a Fischer port, including the PVS-14, PVS-31 series, GPNVG-18 (BNVS), BNVD-1431, and BNVD-31 models. It also works with any night vision housing that uses a 4-pin Fischer interface and USBP-style wiring layout. The cable provides a secure and consistent power transfer connection. It is commonly used by night vision users who run counterweight-style battery packs to increase runtime while maintaining helmet balance and comfort.
The USBP standard layout allows seamless connection with many popular battery packs. It is plug-and-play and does not require any modification to compatible devices. The cable construction provides flexibility to route along a helmet setup, and the locking connectors help prevent accidental disconnection in the field. This cable does not include a battery pack and is designed for users who already have or plan to purchase a compatible remote power source.
The NVG Battery Power Cable is a simple and practical accessory for users who want to upgrade their night vision setup to run external power. It is suitable for law enforcement and professionals who need extended runtime and improved helmet weight distribution.
