CyberPower BP48VL2U01 Extended Battery Module for OL3KRTHD UPS

Overview

The CyberPower BP48VL2U01 is a 2U rackmount extended battery module designed to increase the runtime of the OL3KRTHD online double-conversion UPS. Built around eight sealed lead-acid (VRLA) cells wired to a nominal 48 VDC bus at 9 Ah per cell, this module gives enterprise and security-infrastructure teams a clean, rackmount-native path to longer hold times without moving to a larger UPS chassis. If your data closet, surveillance head-end, or access control panel room needs 15–30 additional minutes of runtime during grid events, this is the component that delivers it — no new UPS, no rewiring, no configuration overhead.

The metal enclosure occupies exactly 2U of rack space and ships in a black finish consistent with standard 19-inch rack aesthetics. At 433 mm tall and 470 mm deep, verify your rack's usable depth before ordering — shallow two-post racks often fall short of the clearance needed for battery modules of this depth.

Key Features

• Eight-Cell VRLA Architecture at 48 VDC: Eight sealed lead-acid cells in series produce a 48 VDC output that matches the DC bus voltage required by the OL3KRTHD. VRLA (valve-regulated lead-acid) chemistry is maintenance-free — no electrolyte topping, no venting infrastructure required — which matters in enclosed IT and security equipment rooms where battery maintenance access is limited.
• 9 Ah per Cell Capacity: At 9 Ah, the module delivers meaningful additional runtime headroom. Actual added minutes depend on the connected load on the OL3KRTHD, but at typical security infrastructure loads (NVR, PoE switches, access control panels), expect a measurable extension over the UPS's internal battery alone.
• 2U Rackmount Form Factor: The 2U rack footprint integrates cleanly into standard 19-inch equipment racks alongside the OL3KRTHD, keeping the UPS and its extended runtime solution in the same vertical stack. Tower orientation is also supported if the deployment uses a floor-standing configuration.
• Metal Enclosure: The all-metal housing provides structural rigidity appropriate for heavy lead-acid cells and contributes to rack weight distribution. Avoid mounting this module at the very top of a tall rack — battery modules are dense and affect rack stability.
• 0–40 °C Operating Temperature Range: VRLA cells are temperature-sensitive; capacity degrades meaningfully above 25 °C. The rated 0–40 °C operating range covers most conditioned equipment rooms, but plan for active cooling if the rack enclosure traps heat — elevated ambient temperature shortens both runtime per cycle and overall battery service life.
• RoHS Compliance: The BP48VL2U01 carries RoHS certification, confirming restriction of hazardous substances in line with EU directive requirements. Relevant for deployments in government facilities, healthcare environments, or any project requiring materials compliance documentation.
• Wide Storage Temperature Tolerance (-15–45 °C): If the module needs to be staged in a warehouse or unconditioned space before installation, the -15 to 45 °C storage range provides reasonable headroom for most North American climate conditions during transit and pre-deployment staging.

Integration and Compatibility

The BP48VL2U01 is verified compatible with the CyberPower OL3KRTHD — a 3kVA/2700W online double-conversion UPS. The module connects directly to the UPS to extend runtime; the OL3KRTHD's battery management circuitry handles charge regulation and runtime estimation automatically once the module is installed. Do not attempt to use this module with other UPS models or voltage configurations — VRLA battery modules are matched to specific DC bus voltages and charging profiles, and mismatched pairings carry a risk of improper charging, reduced service life, or safety issues.

For deployments in network video recorder rooms or UPS and power protection infrastructure supporting security systems, pairing the OL3KRTHD with this battery extension module is a straightforward way to meet extended runtime requirements without oversizing the primary UPS. Integrators specifying access control panels, head-end equipment rooms, or centralized IP camera recording infrastructure will find the 2U rackmount profile convenient for co-location with network and recording gear.

Frequently Asked Questions

Q: Which UPS model is the BP48VL2U01 compatible with?

A: The BP48VL2U01 is verified compatible with the CyberPower OL3KRTHD. Do not use it with other UPS models without confirming DC bus voltage and charging profile compatibility with CyberPower directly.

Q: What battery technology does the BP48VL2U01 use?

A: The module uses sealed lead-acid (VRLA) batteries — eight cells at 12V/9Ah each, wired in series for a 48 VDC bus. VRLA is maintenance-free and requires no electrolyte servicing.

Q: Can the BP48VL2U01 be rack-mounted?

A: Yes. The BP48VL2U01 is a 2U rackmount module compatible with standard 19-inch equipment racks. Tower orientation is also supported. Verify your rack's usable depth — the module is 470 mm deep.

Q: What is the operating temperature range for the BP48VL2U01?

A: The rated operating temperature range is 0–40 °C. VRLA capacity degrades at sustained elevated temperatures, so active rack cooling is recommended if ambient temperatures in the enclosure regularly exceed 25 °C.

Q: Is the BP48VL2U01 RoHS compliant?

A: Yes. The BP48VL2U01 carries RoHS certification, confirming compliance with EU restrictions on hazardous substances in electrical and electronic equipment.

Q: What are the physical dimensions of the BP48VL2U01?

A: The module measures 433 mm (H) × 87 mm (W) × 470 mm (D) and occupies 2U of rack space. Confirm rack depth clearance before installation — shallow racks may not accommodate the 470 mm depth.
