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

I purchased mine NOT to store batteries.
I bought 21700 glow. It fits my KPL knife oil bottles perfectly.
Three slots for oils and one for the Blue Thead Locker Stick.
Have a second one behind that this is holding some tools.
What i need to figure is how to attach them together for stability.
Any suggestions welcome..
Great purchase! Great product!
Perfect for holding spares in your bag. The dayglo helps nicely when you forget to change batteries
If you own 18650 / 21700 batteries and use the Delron cases you possibly have noticed sizing problems for batteries with built-in charging plugs. (They are sometimes very slightly larger and diameter and length ) The Delron battery holders are exactly sized for the standard lithium batteries. This product glows in the dark and accepts small variations in the length and width of the battery. (Which to exist for some batteries with built-in charging plugs). The Delrin battery holders are exact in size and watertight. They hold one single battery. This glow in the dark version made from silicone material is not waterproof but possibly water resistant for splashes and bad weather. I like the fact that it glows in the dark give me located easily and even used as landmark in the dark room. It holds the battery is very securely four at a time. If you're on a boat they need waterproof battery container is used to Delrin. If not I recommend this new product. When you pay around $20 for a quality battery and you have four of them, the price of this container is a bargain. You can drop this thing and it'll absorb the shock protecting the batteries. I recommend getting two. With two battery holders they fit together tightly and have to be pulled apart manually to access the batteries. They're made with precision. The fit is exact however, forgiving for batteries with built-in charging ports.
