Keep critical equipment online longer with the Eaton BP48V27-2US external battery pack. This 48V, 2U rack/tower module is built for environments where the UPS itself is sized correctly, but runtime needs more headroom. Instead of overbuying a larger power platform, teams can add battery capacity where it matters most. The rack/tower design gives deployment flexibility in closets, branch offices, and edge rooms where space and serviceability both matter. As an external battery pack, it is intended to extend ride-through time for compatible UPS systems, helping preserve uptime during utility interruptions, transfer delays, and short generator gaps. For IT teams protecting switches, firewalls, storage, and virtualization hosts, the BP48V27-2US adds practical resilience. It is a straightforward way to improve outage tolerance while keeping the power stack aligned to the load profile. That makes it a strong fit when uptime is worth more than the cost of a basic battery add-on.
