Extended Runtime Battery Module

The CyberPower BP48VL2U01 is a 48 V DC external battery pack that adds runtime to compatible UPS systems. It delivers 70 A output current from sealed lead-acid cells and mounts in a standard rack. The unit accepts 100-125 V AC input through a NEMA 5-15P plug and recharges to 90 % capacity in four hours.

Suited for Rack Environments Needing Extra Autonomy

IT managers who need longer backup for servers or network gear in a 2U rack space will find this module fits. Buyers who want more storage capacity than the four 12 V 9 Ah cells provide should look at higher-capacity alternatives. The 65.26 lbs weight also means installers must plan for safe handling and rack load limits.

Output Voltage and Current Define Compatibility

The module supplies 48 V DC at 70 A, so the host UPS must match that voltage and accept the current rating. UL 1778, CSA C22.2 No. 107.3 and FCC Part 15 Class A approvals confirm regulatory compliance for North American installations. Operating temperature range is 32-104 °F with 0-90 % non-condensing humidity.

Questions about this item

How do I install the BP48VL2U01 in a rack, and what step is often missed?

Mount the 3.41" high unit using the included rack ears, then plug the NEMA 5-15P into a 100-125 V circuit; the step often missed is verifying the UPS firmware recognises the added 48 V DC string before applying load.

What maintenance or replacement will the BP48VL2U01 need later?

The sealed lead-acid cells are user-replaceable via the hot-swappable tray; order replacement pack RB1290X4Q when runtime drops below requirement.

What limit appears first during sustained discharge at full load?

The 70 A output current limit is reached before thermal shutdown, so runtime at maximum draw is constrained by the 12 V 9 Ah capacity.
