Four Lithium Battery Cabinet Sizes
Fire-Rated Lithium-Ion Battery Storage Cabinets
Fire-rated lithium-ion battery storage cabinets. Storage only — no charging. 90-minute construction. G90 galvanized 18-gauge steel. Built to NFPA 855 & UL 1487 with UL-/ETL-listed components. Made in the USA.
Built to US Code — Not Converted From European
Most lithium battery cabinets sold in America are European cabinets with a new label. You can see it in their specs: metric steel thickness, RAL paint codes, and EN 14470-1 — a European standard written for flammable liquid cabinets, not batteries.
The Sentinel Mini is built in Santa Rosa, California, to the standards your fire marshal and your insurer actually enforce: UL 1487, NFPA 855, IFC Chapter 12, and OSHA 29 CFR 1910. G90 galvanized steel. Gauge, not millimeters. UL- and ETL-listed components throughout. Made in the USA. 2–4 week lead time.
