About this model

Battery case for a single 18650 battery. I didn't like the other cases I found here so I made a better one. Nice big cap, chunky grip. The long thread makes it possible to fit protected batteries that might be longer than 65 mm. The chunky grip also makes it so it won't roll away. Added a dual version! Added a cr123 version! Added 21700 version!
