The Nitecore NBM40 battery magazine is a storage unit for four 18650 batteries. The battery magazine is a great way to carry around your 18650 units helping protect your batteries from weather and short circuits.
I review the product after using it for around 4 months. Only bad thing I noticed about the battery magazine is it is very hard to get your batteries out. On the other hand, that means your batteries won't fall out by accident.
