First Impressions of Armasight BNVD-40 Battery Pack
The Armasight BNVD-40 Battery Pack promises to extend the operational life of your night vision goggles, a critical factor in tactical scenarios and extended outdoor activities. Armasight, a well-respected name in the night vision industry, offers this battery pack as a dedicated power solution for its BNVD-40 and BNVD-51 night vision devices. This review will delve into whether this accessory lives up to the expectations of serious users who depend on reliable night vision.
My need for the Armasight BNVD-40 Battery Pack stemmed from numerous occasions where my BNVD-40’s internal batteries died mid-operation during nighttime training exercises. The promise of extended runtime and the ability to hot-swap batteries without removing the goggles was a significant draw.
Unboxing the Armasight BNVD-40 Battery Pack, I was immediately impressed by the robust feel of the ULTEM 2300 polymer construction. The included nylon pouch and velcro straps suggested a focus on practical field use, and the interface shoe with connector appeared well-engineered.
While several universal battery packs exist, I opted for the Armasight solution to ensure seamless compatibility and avoid potential issues with voltage or power delivery. Off-brand battery packs can sometimes introduce noise or even damage sensitive night vision equipment. My initial excitement centered on the potential for significantly improved operational readiness and reduced downtime in the field.
Real-World Testing: Putting Armasight BNVD-40 Battery Pack to the Test
First Use Experience
My first field test involved a night navigation exercise in a heavily wooded area. The Armasight BNVD-40 Battery Pack was connected to my BNVD-40 goggles and powered by a fresh CR123A battery. The extended runtime allowed me to focus on navigation without the constant anxiety of battery life.
During the exercise, I experienced heavy rainfall, which tested the battery pack’s weather resistance. The Armasight BNVD-40 Battery Pack continued to function flawlessly, indicating a decent level of protection against moisture. The added weight of the battery pack on the back of the helmet required a slight adjustment to my helmet’s counterweight system.
There were no immediate issues or operational surprises, but I did notice the cable connecting the battery pack to the goggles occasionally snagged on branches.
Extended Use & Reliability
After several months of regular use in various conditions, the Armasight BNVD-40 Battery Pack has proven to be a reliable power source for my night vision goggles. Despite being subjected to mud, dust, and varying temperatures, the ULTEM 2300 polymer casing has held up well, showing no signs of cracking or deformation. Cleaning the battery pack is straightforward, typically requiring only a damp cloth to wipe away dirt and debris.
Compared to relying solely on the internal batteries of the BNVD-40, the Armasight BNVD-40 Battery Pack offers a significant improvement in operational endurance. The extended runtime has allowed for longer observation periods and reduced the need to carry multiple spare batteries. The peace of mind knowing I have a dependable external power source is invaluable in critical situations.
Breaking Down the Features of Armasight BNVD-40 Battery Pack
Specifications
Manufacturer: Armasight.
Color: Black.
Finish: Black.
Fabric/Material: ULTEM 2300.
Field of View, Angle: 40 degrees (Note: This is the FOV of the BNVD-40 goggles, not the battery pack itself. This specification is misleading in the context of the battery pack).
Battery Type: CR123A.
Weight: 7.3 oz.
The Armasight BNVD-40 Battery Pack delivers external power using a single CR123A battery, offering significant extension of the BNVD-40 and BNVD-51’s runtime.
These specifications, while seemingly simple, are critical for understanding the role and performance of the Armasight BNVD-40 Battery Pack. The rugged ULTEM 2300 construction ensures durability in harsh environments, while the CR123A compatibility makes it easy to source replacement batteries. The 7.3 oz weight, while noticeable, is a worthwhile trade-off for the extended power it provides. The listed 40-degree FOV specification is confusing, as it refers to the BNVD-40 goggles themselves, not the battery pack.
Performance & Functionality
The primary function of the Armasight BNVD-40 Battery Pack is to extend the operating time of the BNVD-40 and BNVD-51 night vision goggles, and it performs this task admirably. By utilizing an external CR123A battery, the battery pack significantly increases the time between battery changes, allowing for prolonged use in the field.
One key strength is the ability to hot-swap batteries without needing to remove the goggles, a crucial advantage in tactical situations. The main weakness lies in the potential for the connecting cable to snag on objects, although this can be mitigated with careful cable management. Overall, the battery pack largely meets expectations and fulfills its intended purpose of extending night vision operation time.
Design & Ergonomics
The Armasight BNVD-40 Battery Pack is designed for practical field use, with a focus on durability and ease of integration. The ULTEM 2300 polymer construction provides a robust and weather-resistant casing, capable of withstanding the rigors of demanding environments.
While the 7.3 oz weight is noticeable, the battery pack is designed to be mounted on the rear of a helmet, allowing for a more balanced weight distribution when used in conjunction with front-mounted night vision goggles. There is a slight learning curve associated with managing the connecting cable to prevent snagging, but the overall design is user-friendly.
Durability & Maintenance
The ULTEM 2300 polymer casing provides excellent durability, resisting impacts, abrasions, and extreme temperatures. The battery compartment is sealed to protect against moisture and dust, ensuring reliable operation in adverse conditions.
Maintenance is minimal, typically requiring only a quick wipe-down with a damp cloth to remove dirt and debris. The battery compartment is easily accessible for quick battery changes in the field.
Accessories and Customization Options
The Armasight BNVD-40 Battery Pack kit includes the battery pack itself, an interface shoe with connector, a nylon pouch, and velcro straps for attachment to a helmet or vest. There are no direct customization options for the battery pack itself, but the velcro straps allow for flexible mounting configurations.
The Armasight BNVD-40 Battery Pack is specifically designed for the Armasight BNVD-40 and BNVD-51 night vision goggles and is not generally compatible with other brands or models. Ensuring compatibility with your specific night vision device is paramount before purchasing.
