CyberPower Extended Battery Pack for PR750RTXL2U & PR1000RTXL2U - BP48VP2U01

CyberPower BP48VP2U01 Extended Battery Module for PR-Series Rack UPS

Overview

The CyberPower BP48VP2U01 is a 2U rack-mount extended battery module designed to expand the runtime of CyberPower's Professional Rack Tower XL UPS line — specifically the PR750RTXL2U and PR1000RTXL2U and their LCD variants. It packs eight 12V/7Ah sealed lead-acid cells into a 17.1 x 3.4 x 16.2 inch steel enclosure, delivering a combined 48VDC / 60A output that pairs directly with the UPS inverter stage. If you're protecting rack-mount UPS systems in IT closets, remote surveillance head-end rooms, or edge infrastructure where a 10-minute runtime isn't enough, the BP48VP2U01 is the purpose-built extension that slots into the same rack without extra cabling gymnastics.

Key Features

• Eight 12V/7Ah SLA Cells (48VDC System): The module's eight sealed lead-acid batteries run in series to produce 48VDC at 60A — matching the UPS inverter's DC bus exactly. There's no adapter or converter required; the module connects natively and the UPS firmware recognizes the added capacity automatically, extending runtime proportionally based on load.
• Hot-Swap Battery Design: Both the module as a whole and its internal battery cartridges (RB1270X4H, qty 2) are hot-swappable. That means a battery replacement on a live system doesn't require a maintenance window or a controlled shutdown — critical when the UPS is guarding always-on security infrastructure or network equipment that can't tolerate downtime.
• User-Replaceable Cartridges: When cells eventually age out (typically 3–5 years for SLA under continuous float charge), you can swap the two RB1270X4H cartridges yourself without sending the unit in. Replacement cartridge cost is far lower than a full module, and the user-serviceable design avoids depot turnaround delays.
• 6-Hour Typical Recharge Time: The built-in charger refills the module in approximately 6 hours from a fully discharged state. For environments with frequent short outages, this means the extended battery is ready well before a second event would typically arrive — though back-to-back utility failures within the recharge window remain a risk to plan around.
• Universal Input (100–240 VAC, 50–60 Hz, IEC-320 C14): The IEC C14 input handles anything from 100V/50Hz to 240V/60Hz, so the same module ships and installs in North America, Europe, and Asia-Pacific deployments without voltage selectors or transformers. International integrators stocking spares for multi-region deployments benefit from a single SKU.
• 2U Rack Form Factor (Steel Construction): At 17.1 x 3.4 x 16.2 inches and 55.8 lbs, the BP48VP2U01 occupies 2U of rack space and is built from metal — not plastic — which matters in dense rack environments where neighboring equipment generates heat and vibration. Budget 56 lbs of load on your rack rails when planning mounting position.
• Operating Range: 32–104 °F (0–40 °C), 0–95% RH Non-Condensing: Standard data-center and IT-closet temperature ranges are covered. The 104 °F ceiling is worth watching in poorly ventilated rack enclosures or outdoor-rated equipment rooms in hot climates — SLA batteries lose capacity and lifespan significantly above this threshold.
• RoHS Compliant + UL / FCC / CE / VCCI Safety Certifications: The BP48VP2U01 carries the certifications required for deployment in regulated enterprise, government, and commercial facilities across North American and international jurisdictions. RoHS compliance also satisfies sustainability procurement requirements in regions where that's a formal purchasing criterion.
• Extended Warranty Option (WEXT5YR-BP1): CyberPower offers an optional 5-year extended warranty (WEXT5YR-BP1) beyond the standard 3-year limited coverage, available for purchase separately. For infrastructure in hard-to-service locations, the extended option reduces lifecycle replacement planning risk.

Integration & Compatibility

The BP48VP2U01 is validated for use with the following CyberPower models: PR750LCDRTXL2U, PR750RTXL2U, PR1000LCDRTXL2U, PR1000RTXL2U, PR1500LCDRTXL2UA, PR750RTXL2UC, and PR1000RTXL2UC. Confirm your UPS model number before ordering — the 48VDC bus is specific to the PR-series XL line. Other CyberPower rack UPS families (OL-series, standard PR without XL suffix) use different bus voltages and are not compatible. For OL-series or higher-wattage PR models, see the corresponding BP-series modules in the battery backup accessories line.

Each BP48VP2U01 ships with two replacement battery cartridge slots accepting the RB1270X4H cartridge. When ordering replacement cells down the line, source the RB1270X4H (quantity 2 per module) to maintain compatibility and warranty coverage.

Frequently Asked Questions

Q: Which UPS models are compatible with the BP48VP2U01?

A: The BP48VP2U01 is validated for the PR750LCDRTXL2U, PR750RTXL2U, PR1000LCDRTXL2U, PR1000RTXL2U, PR1500LCDRTXL2UA, PR750RTXL2UC, and PR1000RTXL2UC. It is not compatible with OL-series or standard PR models without the XL suffix — those use different DC bus voltages.

Q: Can I replace the batteries myself without a service call?

A: Yes. The BP48VP2U01 supports user-replaceable batteries via two RB1270X4H cartridges (each containing four 12V/7Ah SLA cells). The module is also hot-swappable, so replacement can be performed on a live system without shutting down the connected UPS or load.

Q: What is the warranty on the BP48VP2U01?

A: The BP48VP2U01 carries a 3-year limited warranty from CyberPower. An optional 5-year extended warranty (WEXT5YR-BP1) is available for purchase separately.

Q: How long does the BP48VP2U01 take to recharge after a discharge event?

A: Typical recharge time from fully discharged is approximately 6 hours. The built-in charger handles this automatically; no external charger is needed.

Q: Does the BP48VP2U01 work in international (non-US) installations?

A: Yes. The IEC-320 C14 input accepts 100–240 VAC at 50–60 Hz, covering North American, European, and Asia-Pacific power standards without modification. Certifications include UL, CE, FCC, VCCI, and RoHS, supporting deployment across multiple jurisdictions.

Q: How much does the BP48VP2U01 weigh, and how much rack space does it require?

A: The module weighs 55.8 lbs (25.31 kg) and occupies 2U of rack space at 17.1 x 3.4 x 16.2 inches. Verify rack rail load ratings before installation, as the weight is significant in high-density configurations.

Ted Perry

The BP48VP2U01 is one of those units I recommend specifically when integrators ask how to extend runtime on a PR750RTXL2U or PR1000RTXL2U without swapping the UPS itself. Eight 12V/7Ah SLA cells running in series give you a native 48VDC bus match — the UPS sees the extra capacity immediately without any configuration step, and the 60A delivery rating means you're not creating a bottleneck at the DC stage.

Technical Highlights:

• 48VDC / 60A Output: Matches the PR-series XL inverter bus directly — no step-up converter, no efficiency penalty from voltage mismatch. The UPS firmware reads the added capacity and adjusts runtime estimates automatically.
• Hot-Swap + User-Replaceable Cartridges (RB1270X4H x2): Live battery swap without a maintenance window is the real operational advantage here. When cells degrade (typically after 3–5 years of float service), two RB1270X4H cartridges bring the module back to spec at a fraction of the replacement module cost.
• 6-Hour Recharge Cycle via Built-In Charger: The internal charger runs the full recharge cycle automatically after an outage — no external charger to provision or track. In environments with daily short-duration utility events, the 6-hour window means you'll typically be fully charged before the next event arrives.

Deployment Considerations:

• At 55.8 lbs in a 2U footprint, rack rail load ratings become a real planning factor — especially in open-frame racks or older cabinets with lightweight rails. Verify weight limits before positioning the module near the top of a tall rack.
• The 104 °F (40 °C) operating ceiling is the spec most often overlooked in security head-end rooms and telecom closets that lack dedicated HVAC. SLA batteries held above this threshold lose capacity faster and may trigger thermal protection events — verify ambient temperature before installation.

For a PR750RTXL2U or PR1000RTXL2U guarding a multi-camera NVR stack or a 24/7 access control server room where even a 15-minute outage causes recording gaps or door controller resets, the BP48VP2U01 is the purpose-matched extension — not a generic UPS upgrade, but the exact battery module the platform was designed to accept.
