Learn how to install the PVS31 Battery Retention System on your helmet with clear steps, common mistakes to avoid, and practical tips for a secure fit.

Quick Answer

To install the PVS31 Battery Retention System, you'll mount the battery pack to your helmet using the existing features already found on the helmet. Follow the steps below for a secure and reliable setup.

Why Proper Installation Matters

A loose or incorrectly mounted battery pack can shift during movement, causing discomfort and potentially disconnecting power to your night vision device. Proper installation ensures the battery pack stays put, even during active use.

The PVS31 Battery Retention System is designed to work with the features already present on your helmet, so you don't need additional modification. This keeps installation straightforward while maintaining a low-profile setup.

What to Check Before You Start

Before installing, verify that your helmet has the necessary mounting points. The system uses existing helmet features, so compatibility is key. If you're unsure, dry-fit the components without tightening to see how they align.

Also, note that the thermoplastic color may vary from the images on the website due to ongoing product updates. The design remains the same, so the installation process is unaffected.

Installation Steps

Gather Your Gear: Collect the PVS31 Battery Retention System, your helmet, and the battery pack. Ensure you have a clean, well-lit workspace. Check that all components are present before starting.
Position the Battery Pack: Place the battery pack against the helmet in the desired position, aligning it with the existing mounting features. Hold it in place with one hand. Double-check alignment before securing; misalignment can cause a loose fit.
Secure the Retention System: Slide or snap the retention system over the battery pack and engage the existing helmet features. Apply even pressure until you hear or feel a click. If it doesn't click, reposition and try again—don't force it.
Test for Stability: Gently shake your helmet to ensure the battery pack is secure. It should not move or rattle. If it does, remove and reinstall, paying attention to the alignment. A secure fit is essential for reliable performance during movement.
