Perfect solution - Nitecore NBM40 Battery Magazine

This is a great container to safely store and carry your 18650 batteries in a compact way. I like the yellow color it is so much easier to spot in my gear. Good purchase and good protection for your expensive batteries.
I have used it during camping and scouting outings and I feel good knowing that I will have extra batteries if I need during nighttime hunts and they are easy to find, especially compared with the small plastic 2 cell containers that I had been using.
