Thyrm Llc Cellvault 18 Battery Storage For 18350 And 18650 Fde
If you run modern tactical lights, you know the value of keeping spare 18650 and 18350 batteries ready without letting them bounce around loose in your pack. The Thyrm CellVault-18 battery storage case is a purpose-built MOLLE-mounted solution that keeps your premium rechargeable batteries protected, organized, and instantly accessible. Unlike generic battery pouches, this FDE case combines weatherproof construction with quick-access design—so you're never fumbling in the dark or risking a drained battery when you need light most.
The CellVault-18 holds either one 18650 or two 18350 batteries in a slim profile that takes up less than a single MOLLE column, making it easy to mount on vests, chest rigs, or pack shoulder straps without bulk. The waterproof double-layer construction with O-ring seal meets IPX7 rating (submersible to 2 meters for 30+ minutes), so your backup batteries stay dry in rain, creek crossings, or field conditions. Clear side windows let you see at a glance whether you're carrying a full or depleted cell, and silicone foam shock absorption keeps your batteries quiet and protected from impact.
Installation is straightforward: fold the metal locking latch flat, thread the rigid strut through MOLLE webbing, unfold the latch to 90 degrees, and load your batteries positive-terminal-down onto the foam base. The folding latch design gives you a secure, positive attachment with minimal profile. Made and designed in the USA, the CellVault-18 is built for serious users who rely on consistent, accessible power in the field.

Frequently Asked Questions
Can the CellVault-18 hold both an 18650 and 18350 at the same time?
No. The CellVault-18 is designed to hold either one 18650 battery or two 18350 batteries—not a mix of both types simultaneously.
How do you attach the CellVault-18 to a tactical vest or pack?
The case uses a folding metal latch that threads through standard MOLLE or PALS webbing. Fold the latch flat, insert the rigid strut through the webbing, then unfold the latch to 90 degrees and secure. It takes less than a minute and requires no tools.
Will the CellVault-18 keep batteries safe in wet conditions?
Yes. The waterproof double-layer construction with O-ring seal is rated IPX7, meaning it can be submerged to 2 meters for 30+ minutes. It's designed to protect batteries from rain, splashes, and field exposure.
What's the correct way to load batteries into the CellVault-18?
Insert your battery or batteries with the positive (+) terminal facing downward toward the silicone foam shock absorber at the bottom of the case. This protects the terminal and ensures proper contact.
