APC Smart-UPS SRT 48V 1.5 kVA RM Battery Pack

This external battery pack extends the runtime of compatible APC Smart-UPS SRT uninterruptible power supplies. It is designed for rack-mount installation in server rooms, network closets and data centres requiring longer backup during mains outages. The unit operates at a nominal 48 V DC and is rated for 1.5 kVA connected loads. It targets IT managers and infrastructure teams who need scalable runtime for critical equipment.

Runtime under sustained load

When the UPS draws continuously near its rated capacity, this pack delivers additional minutes of battery power to keep servers and networking gear running until generators start or graceful shutdown completes. Voltage remains stable at 48 V throughout the discharge curve, avoiding the sharp drops seen in undersized packs. The pack is not suited for environments that demand hours of autonomy at full load or for UPS models outside the SRT 48 V product line.

Highlights

  • 48 V battery pack extends runtime for compatible UPS units

Questions about this item

Does the 48 V battery pack generate noticeable heat or fan noise during extended run-time?

The unit is a passive battery module with no internal fans, so it produces no audible noise and only minimal warmth under normal load.

Which UPS chassis must I already have for the SRT48RMBP to connect and function?

It is designed for APC Smart-UPS SRT models that accept a 48 V external battery pack; the host UPS provides the charging circuit and communication link.
