Product Overview

The Eaton BP36V42-3U is a 36V external battery pack for rack UPS systems, designed to multiply available runtime on compatible Tripp Lite and Eaton SmartPro UPS units. As an expandable UPS battery pack rack-mount solution, it uses only 3U of rack space and installs in stacking, upright tower, or rackmount configurations. Facilities that need extended runtime battery for commercial UPS deployments, such as an AV rack that must survive an extended outage without shutting down, can daisy-chain multiple BP36V42-3U units to a single compatible UPS. Heavy-gauge cabling with a high-current DC connector is included for straightforward installation.

Product Description

Eaton BP36V42-3U external battery pack

The BP36V42-3U is a 36V DC battery pack for rack UPS systems specifically engineered to work alongside compatible Tripp Lite SmartPro units, including the SMART1500RMXL2U and SMX1500RTXL2U, rather than functioning as a standalone power device. Its multi-use form factor supports stacking configurations, upright tower placement, or standard 3U rack-mount installation, giving integrators flexibility when planning AV rack layouts that combine UPS, battery expansion, and connected equipment. An additional output connector allows multiple BP36V42-3U units to be daisy-chained together and connected to a single UPS, which is the standard approach for facilities that need substantially longer runtime than an internal battery alone can provide. Heavy-gauge cabling with a high-current DC connector is included, reducing the amount of separate cabling an installer needs to source. This 36V battery pack for AV rack UPS applications is a common upgrade path for conference room and broadcast racks that started with a base UPS unit but later determined their runtime requirements had grown, since it avoids replacing the primary UPS itself.

Key Features

  • 3U Rack-Mount Form Factor — installs in a standard 19-inch rack alongside the primary UPS with included 4-post mounting hardware.
  • Multi-Configuration Design — supports stacking, upright tower, or rack-mount installation depending on the facility's layout.
  • Daisy-Chain Expansion — an additional output connector allows multiple battery packs to be connected to a single compatible UPS.
  • Heavy-Gauge Cabling Included — high-current DC connector cabling ships with the unit for straightforward installation.
  • Compatible with Select SmartPro UPS Systems — designed for Tripp Lite SmartPro units that specify this battery pack, including the SMART1500RMXL2U family.

Typical Applications

  • Conference room AV racks requiring extended runtime beyond base UPS capacity
  • Broadcast studio racks needing long-duration backup for critical equipment
  • Government space AV and IT racks with extended outage requirements
  • Boardroom AV racks supporting extended-runtime UPS configurations
