Available with fire-rated construction. Custom configurations available. Built in Santa Rosa, California.
About the AEL Sentinel
Lithium-ion batteries power everything from military drones and UAVs to data center backup systems and commercial equipment. But these batteries carry serious fire and explosion risks if stored improperly. Overheating, physical damage, and overcharging can trigger thermal runaway — making purpose-built storage critical for safety and regulatory compliance.
The AEL Sentinel™ is a prefabricated battery storage container designed specifically for lithium battery staging, isolation, storage, and charging operations. Each unit is manufactured at our Santa Rosa, California facility and ships ready to install. With integrated environmental controls, proprietary hazard detection, and industrial-grade electrical distribution, the Sentinel provides the containment and safety systems required across military, industrial, commercial, and energy sector applications.

Industries & Applications
Military & Defense
Secure storage and charging for drone, UAV, AUV, and communications equipment batteries. Configurations available to separate charging from bulk storage. Designed to support mission readiness and protect critical battery inventory. Quarantine and incident-response separation capabilities.
Data Centers & Telecommunications
Safe lithium battery containment for backup power systems, UPS battery arrays, and telecommunications infrastructure. Climate-controlled environments maintain optimal battery health. Fire-rated construction available based on proximity requirements to server rooms and occupied spaces.
Commercial & Industrial
Battery storage for warehouses, manufacturing plants, and facilities using lithium-powered equipment including forklifts, power tools, and backup power systems. Climate-controlled environments extend battery service life and reduce fire risk.
EV Dealerships & Automotive
As electric vehicle inventories grow at dealerships and automotive service centers, so does the need for safe, code-compliant battery storage. The AEL Sentinel™ provides EV dealerships with a purpose-built solution for storing replacement battery packs, damaged or recalled batteries awaiting disposition, and batteries removed during service and repair operations. Fire-rated construction and integrated hazard detection protect showroom facilities, service bays, and adjacent customer areas from lithium battery fire and explosion risks.
Energy Storage & Grid Scale
Prefabricated containment for utility-scale battery energy storage systems (BESS). Fire-rated construction with environmental controls protects high-value battery arrays while meeting regulatory requirements for proximity to occupied structures.
Fleet Operations & Transportation
Battery storage and charging containment for fleet operators transitioning to electric vehicles — including delivery vans, buses, trucks, and municipal vehicles. Secure outdoor containers allow fleet yards to store and charge lithium batteries safely without modifying existing buildings.

The Sentinel includes proprietary hazard detection, climate control, fire suppression integration, and industrial-grade electrical distribution.
What fire suppression options are available for the AEL Sentinel™?
The AEL Sentinel™ can be integrated with multiple fire suppression technologies, including dry chemical, thermal-activated aerosol, and clean agent systems. Fire-rated construction is also available. We engineer the enclosure and defined interfaces to support your specific incipient fire response strategy.
What industries use the AEL Sentinel™ for battery storage?
The AEL Sentinel™ serves military and defense operations, commercial and industrial facilities, data centers, telecommunications, EV dealerships, fleet operations, and any operation requiring safe lithium battery staging, isolation, or quarantine and incident-response separation.
Does AEL provide battery storage buildings for military applications?
Yes, AEL specializes in lithium battery storage and charging buildings for military applications. The Sentinel™ supports mission readiness for UAV, AUV, and communications equipment battery operations. We offer configurations to separate charging from storage, protecting critical battery inventory and personnel.
Can EV dealerships use the AEL Sentinel™ for battery storage?
Yes, the AEL Sentinel™ is ideal for EV dealerships that need to store replacement battery packs, damaged or recalled batteries, and batteries removed during service operations. Fire-rated construction and integrated hazard detection protect showroom facilities, service bays, and adjacent customer areas from lithium battery fire and explosion risks. Contact AEL for configurations designed specifically for automotive dealership applications.
How much does an AEL Sentinel™ cost?
Pricing for AEL Sentinel™ units varies based on size, fire rating, fire suppression options, electrical configuration, and customizations. Contact AEL at (888) 502-6695 for a custom quote. Our prefabricated buildings are typically more cost-effective than traditional onsite construction with faster deployment timelines.
What temperature should lithium-ion batteries be stored at?
Lithium-ion batteries generally require a climate-controlled environment to maintain stability and prevent thermal events. The AEL Sentinel™ includes industrial HVAC systems to maintain optimal storage temperatures year-round, protecting your battery investment from extreme heat or freezing conditions.
Does AEL ship Sentinel™ units nationwide?
Yes, AEL manufactures all Sentinel™ units at our facility in Santa Rosa, California and ships nationwide. Our prefabricated containers arrive ready for installation, offering significantly faster deployment compared to traditional construction.
