Storage solution for 18650 and 21700 batteries?

[l2oBiN]

Can anyone recommend a storage case for 18650 and 21700 batteries?

I need a solution for storage of ~10-20 x 18650 and ~6 x 21700.

Also need a solution to take 3-4 batteries as carry on body/backpack when hiking/camping - need to be waterproof, dustproof and impact resistant.

Also takes protected cells. A brand version is the MecArmy B18.
Am in the market for something similar for protected 21700's.

You would do well to use the SEARCH feature on this site to find other threads where battery storage solutions have been extensively discussed. That noted, three of the most commonly endorsed recommendations are:

1. Storacell (storacell.net). Rugged battery protection and storage solutions for cells of all sizes.

2. Nalgene Snap-Cap Vials (Available at usplastic.com // Also available from multiple other online sellers, in multiple sizes; shop around for best prices.)

3. M&M Mini Chocolates --OR-- Skittles.

Etsy has a number of shops making 3D-printed storage solutions for all sorts of battery sizes. Including 18650s and 21700s. Use the Search feature on there. Type in the battery designation and the word "storage" as well.
