- Use your legacy ANVIS / LEMO connector type battery packs with modern BNVD / Fischer connector night vision systems (PVS-31, etc)
- 4-Pin ANVS / LEMO connector on one end, Fischer / BNVD connector on opposite end
- Works with most ANVIS spec battery packs (as wiring can vary between battery pack manufacturers we cannot guarantee compatibility with 100% of battery packs)
