The Batteryclip is so cool I wanted to drop it in the middle of our SHOT show coverage. Offered in AA, CR123A and 9v sizes, they load just like a regular weapon magazine and offer innovative battery management.
The 9v model accommodates 10 batteries and the other 2 hold 8 each. Just like a pistol magazine there are indicator holes at the rear.
The interesting thing is that they weren’t inspired by gun magazines at all but rather were developed simply as a solution for batteries rolling around in bags and pockets.
The Batteryclip is available through Bottom Line Military Sales for individual or GSA purchases.
