Thyrm Llc Cellvault 21 Battery Storage For 21700 & Sl B50 Fde

The Thyrm CellVault-21 is a purpose-built battery storage case for 21700 rechargeable batteries and Streamlight SL-B50 batteries—essential gear for anyone running high-performance tactical lights in the field. Whether you're a competitive shooter, law enforcement professional, or serious hunter who relies on advanced lighting, keeping your spare batteries protected and instantly accessible makes the difference between a light that's ready when you need it and one that's dead when it counts. This isn't just a pouch; it's a weatherproof container engineered to keep your premium batteries safe from impact, moisture, and environmental damage while staying slim enough to integrate seamlessly into existing MOLLE/PALS loadouts.

Built with dual-wall construction and a waterproof O-ring seal rated to IPX7 (submersible to 2 meters for 30+ minutes), the CellVault-21 protects your investment from the elements without compromise. The internal silicone foam shock absorber cushions against impacts and eliminates rattle—critical when silence matters on a hunt or tactical operation. Clear side windows let you verify battery status at a glance without opening the case, and the secure metal latch locks it down tight while remaining confident your gear won't accidentally spill.

What sets this design apart is the attention to practical field use: the slim profile occupies less than one MOLLE column wide, the upgraded latch seats easily even on tight webbing, and the detachable latch system backs up with an included security pin if you need extra retention. Made in the USA, the CellVault-21 trades flashy marketing for solid engineering that works on your belt, pack, or plate carrier when conditions get real.

Frequently Asked Questions

Will this fit my 21700 battery and Streamlight SL-B50?

Yes, the CellVault-21 is designed to hold either one 21700 rechargeable battery or one Streamlight SL-B50 battery. If using the SL-B50, you'll need to remove the foam insert first. Both fit securely with the silicone shock absorber cushioning the battery at the bottom.
