Looking for something that can fit in a pocket that holds some CR123A cells. I'm basically looking for something with a low profiles while in a pocket, and will prevent carrying loose cells in a pocket.
Get one of those Kodak Advantix film canisters at the local drug store. I've gotten a few for free. They can hold two batteries because of the oblong shape. The Fujifilm variety won't work.
Try this from Bug Out Gear USA. http://blackforce.stores.yahoo.net/batterycarrier.html. I use it to carry 8 Tenergy 900 mAh Li-Ion CR123 rechargables (4 on each side) you can take them apart to make them smaller and carry 4 cells in your pocket.
