The Phoenix Safe Battery Commander Safe is a 110V Lithium-ion battery charging and storage safe. Advanced battery-charging safes feature UL-Certified power strips (PDUs) inside for ease and convenience. Durable safes are specially engineered to withstand and contain hard-to-extinguish battery fires, ensuring they don't spread and cause irreparable damage. Completely insulated with sophisticated door seals and double-wall steel construction, each safe provides both great strength and fire/heat resistance. Ventilation port offers easy connection to an external ventilation duct to reduce internal pressure and release toxic gases caused by battery fires. With the multipoint, pick-resistant dimple key lock, safe door will remain securely closed - even in the event of the most severe battery explosion.
