Article 700 or 701 of the National Electrical Code, NFPA 70, the Life Safety Code, NFPA 101, the Fire Code, NFPA 1, the International Building Code, IBC, and the International Fire Code, IFC. LIS provides custom VRLA and Lithium-Ion Battery Systems for Central Lighting Inverters.

Lithium Ion vs. VRLA Battery

The lithium ion battery has not fully been recognized into the the central lighting inverter market as of yet. Challenges of moving from VRLA batteries to lithium based inverters derive from the short duration runtime burst lithium ion batteries provide. LIS works with OEM’s who can apply certified UL 924 certified Lighting Inverters and UPS systems, that also work with longer runtime lithium ion battery systems. The 90 minute rating can be achieved. Lithium provides longer life batteries and much less maintenance attention.
