The Thyrm CellVault, CellVault XL, CellVault-18, CellVault-21, and CellVault-5M are waterproof, attachable gear solutions. They were designed for battery storage, but can store many things in their food-safe plastic, including survival gear and medicine. You can read a catalog for all CellVaults in this product line (PDF).
The CellVault comes in five sizes:
-
- CellVault is the original size, designed specifically for CR123s, though it also fits AAA and AA alkaline batteries well.
- CellVault XL is twice the original size, giving a lot more storage options for CR123s, AAAs, and AAs, but also fits two 18650s.
- CellVault-18 was designed specifically to fit rechargeable 18650s and 18350s, as well as smaller batteries.
- CellVault-21 was designed to store rechargeable 21700 batteries, as well as smaller batteries.
- CellVault-5M was designed specifically to store CR123s, 18650s, 18350s, and CR2032 batteries in modular configurations made more customizable with an additional Modular Insert Pak that enables it to also hold AAA and 1632 batteries, and with Battery Patches.
