Eaton BP48V24-2U – 48V Rack-Mount External Battery Pack

Product Overview

The Eaton BP48V24-2U is a rack-mount external battery pack built to extend runtime on compatible 48V DC UPS systems used in data centers, network closets, and other commercial equipment rooms. Integrators and IT managers deploying a UPS battery expansion for extended runtime rely on this enclosure to add backup capacity without swapping out the primary UPS unit. It ships with an attached DC cable and blue 175-amp connector for a direct connection to the host system, and it installs into a standard 19-inch rack alongside the UPS it supports. This makes it a practical option for any commercial-grade power protection deployment where downtime is not acceptable.

Product Description

The BP48V24-2U is a 2U rack-mount external battery pack enclosure designed for Eaton Tripp Lite series 48V DC UPS systems. It is a purpose-built accessory for extending backup runtime beyond what the internal batteries of a compatible UPS can provide, which matters for facilities running network switches, servers, or AV control equipment that cannot tolerate a hard power loss. The unit mounts using included 4-post rackmount hardware, and optional 2-post adapter kits are available for open-frame racks common in network closets and telecom rooms. Installation is straightforward: the battery pack connects to the host UPS through its attached DC cable, and up to two BP48V24-2U units can be paired to a single supported UPS system using the 48VDCSPLITTER accessory for even greater runtime extension.

Because it shares the same 48V DC architecture as its compatible UPS line, the BP48V24-2U is a common addition in data center rack-mount UPS deployments, server room power protection projects, and network closet buildouts where a facilities or IT team wants headroom against extended outages. Commercial integrators specifying rack-mount battery backup for a client's server room or network closet often add one or more of these packs at the time of the original UPS install, since the enclosure occupies rack space that should be planned for in advance. The unit carries UL Listing along with CE, RoHS, and NOM compliance, making it suitable for both domestic and international commercial deployments.

Key Features

• 2U Rack-Mount Enclosure — Fits standard 19-inch equipment racks used in data centers and network closets, keeping the expansion battery in the same footprint as the host UPS.
• 48V DC System Compatibility — Matches the DC bus voltage of compatible Eaton Tripp Lite 48V UPS systems for direct, plug-in runtime extension.
• Attached DC Cable with 175A Connector — Simplifies installation with a pre-wired, color-coded connection to the host UPS.
• Expandable to Two Units — Supports pairing two BP48V24-2U packs to a single UPS via the 48VDCSPLITTER accessory for additional runtime.
• 4-Post and 2-Post Mounting Support — Includes 4-post rackmount hardware, with optional adapter kits for 2-post rack installations common in telecom and network closets.
• Commercial-Grade Certifications — UL Listed and CE, RoHS, and NOM compliant for use in commercial and international deployments.

Typical Applications

• Data center rack rows requiring extended UPS runtime
• Network closets supporting switches, routers, and PoE equipment
• Server rooms where extended outages must not interrupt operations
• Government and commercial facilities with critical infrastructure uptime requirements
