Great product I have multiple of these cases I keep them in multiple gear bags that may find themselves in austere environments.

Almost perfect

I have 3 of these cases now. Getting ready to buy another couple after harvesting some more 18650s. I night hike quite a bit with a couple of different Fenix headlamps that run 18650s so one of these rides in my backpack 24/7 and I don't have to worry about my backup batteries getting wet, dirty, damaged or shorting out on something. Fits both my protected and flattops perfectly.

Wish the foam insert came permanently attached but I can fix that myself.

Perfect.

I have 6 of these now. They're thick and durable, but light and compact. Well sized for a cupholder, saddle pocket or backpack pocket. I haven't tested, but I'm very confident in water resistance and shock response. These have made a lot of night adventures very fluid, and extended work shifts easier. Every Mecarmy product I own has been worth its price 10x over.

Sturdy Storage

This case is built solidly and seals tightly. You can't stack it like you can the flat rectangular cases, but it would be fine for dropping in a backpack.

18650 battery case
December 2, 2020
Holds six 18650 batteries securely. Comes with a fitted foam insert under the cap. It's loose when there are no batteries but when the batteries are loaded, prevents them from moving thus creates a solid and stable housing. Fits all kinds of 18650s; protected or not. The plastic of the case is smoked so you can see the batteries inside. The case also comes with a lubed O-ring so the case should be waterproof. Overall, a great case for the adventurer who needs a dependable, durable, weatherproof case for batteries.
