Keep ITA2 power protection online longer when runtime matters most. The Vertiv ITA2 Lithium PWR Protect EBC LI 2U is an external battery cabinet designed to extend backup duration for compatible rack-mounted UPS deployments. Its lithium battery architecture supports a smaller footprint than traditional battery strings while helping reduce maintenance demands over the life of the system. For data centers, edge rooms, and distributed IT sites, added runtime is not a convenience feature — it is a control point. More battery capacity gives teams time to ride through short outages, bridge generator start delays, and complete graceful shutdown procedures when utility power is unstable. The 2U rack form factor keeps the installation clean and predictable, making it easier to standardize power protection across multiple racks. This model is a strong fit when the base UPS is already specified and the requirement is longer autonomy, not a larger UPS chassis. That makes it a practical way to protect higher-value workloads without overbuilding the entire power chain. For organizations that measure downtime in business impact, an external lithium battery cabinet is a targeted investment in continuity.
