Epoch Batteries 2x 18650 Battery Case - Black

High integrity for such lightweight.

Case is a little thin but it's ok

The cases work very well for my 18650 unprotected batteries. I usually stick a spare case in my backpack during hikes for flashlights and headlamps. I do wrap the case with Ranger Bands to insure the case doesnt open in my pack. Plastic hinges may eventually wear out but they are only 50 cents. More concerned with batteries rolling around in my pack but bands take care of that concern.
