APC Smart-UPS 48V 2U Rack-Mountable Battery Pack

The APC SRT48RMBP is a 48V external battery pack built for Smart-UPS systems that need extended runtime and dependable backup power. Housed in a 2U enclosure that comes in a black finish, it holds two sealed lead-acid batteries and fits neatly into any standard 19-inch rack or can stand beside a tower UPS.

APC engineered this pack for seamless use with specific Smart-UPS models, including the SMX1000I-DIG and SMX1500RMI2UNC-5XW. Installation is straightforward: attach the supplied mounting brackets, connect the DC cable, and the unit is ready to extend your UPS without additional configuration.

During an outage, the battery pack allows servers, network switches, and storage arrays to stay online long enough for a graceful shutdown or for a generator to start. Its 2U height conserves valuable rack space, making it especially practical for branch offices, edge computing deployments, and small to medium data centers where every rack unit counts.

Maintenance remains simple thanks to hot-swappable battery trays that slide out from the front. Technicians can replace a depleted module in minutes while the UPS continues to supply power, keeping critical services available. A two-year warranty offers additional peace of mind for administrators who depend on continuous protection.
