Product Identity

The APC SMX48RMBP2US is a 48V external battery pack designed for Smart-UPS X-Series units. It provides extended runtime for critical servers and network equipment in rack or tower configurations. This unit suits IT managers who need scalable backup power for existing UPS installations.

Installation Notes

The pack mounts in standard racks or stands as a tower to match the host UPS form factor. Connection uses the dedicated external battery port on compatible Smart-UPS X-Series models. Installers must verify the host UPS firmware supports this battery pack before applying load.

Sustained Operation

During extended outages the pack discharges in parallel with the internal UPS batteries to maintain output voltage. The sealed lead-acid cells are rated for repeated deep cycles at the 48V system voltage. Thermal management relies on the host UPS enclosure airflow rather than integrated fans.
