If you are a fan of high capacity 18650 and 21700 batteries like us you will appreciate the 4 Bay Battery Mag, By Maratac®,

18650 and 21700 batteries hold a lot of energy in a small package that can be dangerous unless treated properly. That being said, carrying these batteries loose in your backpack unprotected can be dangerous.

We designed the 4 Bay Battery Mag to carry and protect our own spare cells from dangerous shorting and impact.

These battery mags are made from silicone to form a light weight, robust protective housing to protect your cells. they can either be used singly to protect the contacts of four of your batteries, or they can be doubled up to completely cover four of your cells and provide maximum protection from shock, shorting and impact.

We made the 4 Bay Battery Mag out of heat resistant silicon in a number of vibrant colors. We offer the 4 Bay Battery Mag, By Maratac® in two different sizes to fit either 18650 or 21700. (Sorry one size does not fit both of these cells.)

Can easily add a second 4 Bay Battery Mag by Maratac® to cover the back terminals if desired
