Extended Battery Module for OL3KRM UPS

The CyberPower BP48VL2U02 is a 48 VDC extended battery module designed for the OL3KRM uninterruptible power supply. It contains eight sealed lead-acid batteries rated at 12 V / 7 Ah each and delivers a 70 A output. The unit fits a 2U rack or tower form factor and includes mounting hardware.

Replaces internal battery set when runtime must

This module replaces the standard internal battery configuration of the OL3KRM and adds hot-swappable capacity without shutting down the load. A built-in charger supports a typical recharge from zero to ninety percent in four hours. Daisy-chain expansion is available for further runtime scaling using the same cartridge type.

Suits IT managers extending backup time on OL3KRM

Buyers who need longer runtime for critical rack-mounted equipment will benefit from the hot-swap design and smart battery management. Users whose UPS model is not the OL3KRM or who require a different voltage platform should look at other compatible battery modules.

Questions about this item

Will the 3.41'' x 17.05'' x 18.31'' module fit in a standard 2U rack slot?

Yes, the unit is a 2U rack/tower form factor measuring 3.41 inches high, 17.05 inches wide and 18.31 inches deep, so it occupies a standard 2U space.

How do I install the BP48VL2U02 and what step is often missed?

Mount the module using the included hardware, connect the daisy-chain cable to the UPS, then press the battery breaker on the rear panel to energise the circuit — skipping the breaker leaves the pack offline.

Which replacement cartridge does the BP48VL2U02 use and how many are needed?

It uses two RB1270X4L cartridges, each containing four 12 V / 7 Ah sealed lead-acid cells, for a total of eight user-replaceable batteries.
