For powering the Voodoo S, a lot of folks prefer using remote rail battery packs or AC/DC power cables to avoid constantly swapping out CR123 batteries. You can usually find these on specialized tactical gear websites or directly from manufacturers who make accessories for night vision and thermal optics.
Some popular places to check include:
- OpticsPlanet
- Tactical Night Vision Company (TNVC)
- Primary Arms
- Brownells
They often carry a range of power solutions, including remote battery packs and power cables that are compatible with the Voodoo S. Another option is to check out forums or communities dedicated to night vision gear—sometimes people will share their setups and where they sourced their equipment.
