Battery Holder Mounts?

[sonrider657]

Does anyone know of any battery holder mounts other than those that are incorporated into buttstocks? My Xenon light eats CR123 batteries and I'd like a convenient way to carry a spare pair on my gun.

Alot of the pistol grips and VFG have compartments for batteries like TD's, Magpuls, Ergos and others. When I was in the field I always just stuck them in a pocket inside a ziplock bag.
