Thyrm Llc Cellvault 21 Battery Storage For 21700 & Sl B50 Black
$24.29
The Thyrm CellVault-21 battery storage keeps your spare 21700 rechargeable batteries and Streamlight SL-B50 cells safe, dry, and instantly accessible on your gear. If you run advanced tactical lights—especially multi-battery rigs where a dead cell means downtime—protecting premium batteries from moisture, impact, and corrosion is non-negotiable. The CellVault-21 does that job with a rugged, compact design that plays nice with MOLLE/PALS webbing and doesn't bloat your load-out.
Built with dual-wall construction and a waterproof O-ring seal rated to IPX7 (2 meters, 30+ minutes), this pouch shields your battery from the field conditions that kill electronics. The clear side windows let you check battery status without opening the case, and a silicone foam shock absorber cradles the cell against impacts and eliminates rattle. The upgraded metal latch is rock-solid and designed to install smoothly even on tight webbing—a real quality-of-life upgrade over older designs. At less than one MOLLE column wide, it tucks onto your vest, pack, or belt rig without eating real estate.
The detachable latch system means you can swap it between platforms, and Thyrm includes a security pin for extra retention if you're running aggressive terrain. Made in the USA, this is the kind of accessory that prevents the worst-case scenario: a dead light when you need it most. Whether you're a serious shooter maintaining backup optics, a tactical professional, or an outdoors enthusiast who demands reliability, battery storage that actually works is foundational gear.

Frequently Asked Questions
What batteries does the CellVault-21 hold?
The CellVault-21 is designed to hold one 21700 rechargeable battery or one Streamlight SL-B50 battery (note: foam must be removed from the SL-B50 to fit). Do not mix or stack multiple batteries inside the case.
Will this pouch work on my tactical vest or pack?
Yes. The detachable metal latch system is compatible with all standard MOLLE/PALS webbing. The slim profile takes up less than one MOLLE column width, so it integrates easily into existing gear setups. You can move the latch between different platforms as needed.
Is it really waterproof?
The CellVault-21 features a waterproof O-ring seal rated to IPX7, which means it can be submerged to 2 meters for 30+ minutes. This protects your battery from rain, water crossings, and moisture in wet conditions, but it's not designed for indefinite submersion.
How do I attach it to my gear?
The detachable latch strips out of the back strap (use a screwdriver on the release tab). Thread the back strap through your MOLLE/PALS webbing, align the side tabs, and snap the latch back in. An included security pin can be added through both the latch and back strap for extra security on rough terrain.
