APC Smart-UPS X-Series External Battery Pack Rack/Tower 48V, 864VAh, rackmount, 2U, TAA

The APC SMX48RMBP2US is an external battery pack designed for Smart-UPS X-Series systems that need longer runtime than a standard UPS can provide on its own. It supplies 48 V DC and holds 864 VAh of capacity, so critical servers, networking switches, point-of-sale stations, and other essential electronics can stay online through extended outages or during planned maintenance.

This pack connects directly to a compatible Smart-UPS X-Series UPS, creating a seamless power extension that the UPS recognizes and manages automatically. Data centers, branch offices, retail locations, and government facilities that rely on uninterrupted operation will find it particularly useful when downtime is not an option.

Intelligent charging circuitry regulates the batteries to maximize lifespan, while the integrated monitoring board lets you check remaining runtime and battery health through your UPS interface. The unit can sit in a standard 19-inch rack using only 2U of space, or you can deploy it in a tower orientation next to the UPS—ideal when floor space is limited.

Inside the black steel enclosure are two sealed lead-acid batteries that require little maintenance yet deliver dependable performance. The pack weighs 63 lb and measures 3.5 in high by 17 in wide by 19.3 in deep, making it easy to plan rack layouts. TAA compliance allows installation in federally regulated environments, and APC backs the product with a two-year repair or replace warranty for added assurance.
