QDEF // COUNTERCELL V2 Quad Defense CounterCell™ V2 Helmet counterweight. Battery storage. One clean package. The Quad Defense CounterCell™ V2 is a purpose-built rear helmet counterweight and battery-storage system designed to help balance front-heavy night vision setups while keeping essential batteries organized, secure, and immediately accessible. V2 introduces an updated shock-cord retention system in place of the original screw closure, providing fast access while keeping the lid securely retained during movement, transport, and field use. CounterCell V2 also significantly increases available counterweight capacity, allowing users to tune helmet balance around everything from lightweight monocular setups to heavier binocular and panoramic night vision systems. Available in Short and Tall configurations, CounterCell V2 lets you choose the storage capacity and counterweight range that best matches your helmet setup. 01 // COUNTERCELL V2 TALL The CounterCell V2 Tall is designed for users running heavier front-mounted systems or who want maximum battery storage and counterweight adjustability. Its larger internal volume makes it well suited for dual-tube systems, panoramic night vision, external-power setups, and helmets carrying additional front-mounted accessories. Battery Storage 2 × 18650 batteries or 4 × CR123 2 × CR2032 2 × AAA 2 × AA Counterweight Capacity Up to 12 oz of counterweight. The modular internal weight capacity allows users to add only the amount of rear weight required to balance their individual helmet and night vision configuration. Best For: heavier binocular systems, panoramic night vision, external battery-pack configurations, and users who want maximum adjustment range. 02 // COUNTERCELL V2 SHORT The CounterCell V2 Short provides the same core design in a lower-profile package for users who want effective helmet balance and essential battery storage without the additional height of the Tall configuration. It's an excellent fit for PVS-14s, lightweight binocular systems, patrol helmets, training setups, and streamlined night vision configurations. Battery Storage 2 × CR123 2 × CR2032 2 × AAA 2 × AA Counterweight Capacity Up to 9 oz of counterweight. The Short configuration provides substantial balance adjustment while maintaining a compact rear-helmet footprint. Best For: PVS-14s, lightweight dual-tube systems, patrol helmets, training helmets, and low-profile builds. 03 // SHOCK-CORD RETENTION CounterCell V2 replaces the original screw-fastened lid with a shock-cord retention system. The updated design keeps the lid securely closed while allowing faster access to internal batteries and counterweights without having to remove or manipulate a threaded fastener. The shock cord keeps the closure system simple, lightweight, and easy to operate while wearing gloves or working in low-light environments. 04 // MODULAR COUNTERWEIGHT SYSTEM Helmet balance depends on the night vision system, mount, helmet, battery configuration, and additional accessories being used. CounterCell V2 allows the user to tailor rear weight to the actual setup rather than being locked into a fixed counterweight. Short: adjustable up to 9 oz Tall: adjustable up to 12 oz This makes it possible to fine-tune balance as equipment changes without replacing the entire counterweight system. 05 // KEY FEATURES Integrated helmet counterweight and battery storage Shock-cord lid retention for secure, fast access Up to 9 oz counterweight capacity in the Short configuration Up to 12 oz counterweight capacity in the Tall configuration Dedicated storage for common night vision and accessory batteries Modular weight configuration for fine balance adjustment Low-profile rear-helmet mounting Velcro-backed mounting surface for compatible helmet loop fields Designed for professional night vision helmet setups Designed and produced by Quad Defense 06 // COMPLETE THE REAR HELMET SETUP CounterCell V2 pairs well with the Forge Concepts Night Vision Battery Pack Retainer for users running an external NVG battery pack alongside their counterweight system. View the Forge Concepts Battery Pack Retainer → 07 // A QDEF ORIGINAL CounterCell V2 was developed by Quad Defense around a simple problem: modern night vision helmets need both better balance and organized battery storage without adding unnecessary bulk or complexity. V2 builds on the original CounterCell with significantly increased counterweight capacity and a simplified shock-cord retention system. QUAD DEFENSE // COUNTERCELL V2 Balance the helmet. Carry the power.
