APC Smart-UPS X-Series 48V External Battery Pack Rack/Tower

The APC SMX48RMBP2U is an external 48V battery pack built for the APC Smart-UPS X Series. By adding this pack to your existing Smart-UPS, you can keep servers, network switches, or point-of-sale equipment running far longer during a power outage. The enclosure slides into rack space that uses the standard 2U height or stands upright as a tower, so it adapts easily to the layout you already have.

Installation is straightforward and requires no special tools. A plug-and-play connector links the pack to the UPS, and the included brackets let you secure it right away. The batteries inside are hot swappable, which means you can replace them while connected equipment remains powered. An integrated battery management system controls charging with precision, extending overall battery life and helping you plan maintenance before it becomes urgent.

IT managers who need additional runtime for server rooms, telecom closets, or edge computing sites will appreciate the flexibility. When your load grows, you can attach extra packs to the same UPS in minutes, creating a clear path for future expansion without disruptive rewiring.
