CyberPower Extended Battery Pack for PR1500RTXL2U PR2000RTXL2U PR2200RTXL2U & - BP48VP2U02

CyberPower BP48VP2U02 Extended Battery Module for PR-Series Rack UPS

Overview

The CyberPower BP48VP2U02 is a 2U rack-mount extended battery module designed specifically to expand runtime on CyberPower's PR1500RTXL2U, PR2000RTXL2U, PR2200RTXL2U, and PR3000RTXL2U smart app UPS systems. It delivers a 48 VDC battery string built from eight 12 V / 9 Ah sealed lead-acid (VRLA) cells, adding meaningful runtime headroom without requiring a new UPS chassis. At 66.2 lb in a standard 2U form factor (17.1 × 3.4 × 19.7 in), it slots directly into existing rack infrastructure alongside compatible UPS units. If you're protecting a server room, edge compute closet, or network operations environment that can't tolerate abbreviated battery backup windows during extended grid events, this module directly addresses that gap.

Key Features

• 48 VDC / 70 A Battery String: Eight 12 V / 9 Ah VRLA cells wired to produce a 48 VDC output string with a 70 A circuit breaker — the circuit breaker is not just a safety feature, it prevents catastrophic discharge faults from cascading into the connected UPS, which matters in high-density rack environments where a single fault can take down multiple systems.
• Hot-Swappable Batteries: Batteries can be replaced under load without powering down the connected UPS — a hard requirement in 24/7 environments like data closets and NOCs where any maintenance window that requires a controlled shutdown carries operational risk. User-replaceable design keeps this work internal rather than requiring a service call.
• Replacement Battery Cartridge RB1290X4J (Qty 2): When cells reach end-of-life, the module takes two RB1290X4J cartridges — knowing the exact replacement part upfront simplifies your spares procurement and eliminates guesswork during a time-sensitive battery swap.
• 6-Hour Typical Recharge Time: After a full discharge event, the built-in charger restores the battery string to full capacity in approximately 6 hours — fast enough to be ready for a second grid event within a single workday, which is relevant in areas with frequent or repeated power interruptions.
• IEC-320 C14 Input with 100–240 VAC Range: The wide input voltage range (100–240 VAC) means this module works on both North American and international power infrastructure without voltage converters. The C14 input plug is standard rack power infrastructure — no custom cabling required.
• Operating Temperature 32–104°F (0–40°C): VRLA batteries are sensitive to temperature, and this range is typical of conditioned server room environments. Running above 40°C shortens battery life measurably — factor that in if you're deploying in an uncooled edge location.
• RoHS Compliant, Safety Certifications CE / UL1778 / cUL / FCC Class B / VCCI / RCM: UL1778 is the specific UL standard for uninterruptible power supplies — not just a generic electrical safety cert. This matters for insurance requirements and facility approval in commercial and enterprise installations. FCC Class B covers radiated emissions, relevant if this module is co-located with sensitive RF equipment.
• 3-Year Limited Warranty: CyberPower covers this module for three years — longer than the typical 1–2 year coverage common on third-party battery packs, and important when sizing total cost of ownership across a multi-year deployment lifecycle.
• Extended Warranty Option WEXT5YR-BP1: An optional 5-year extended warranty is available (WEXT5YR-BP1), extending coverage without requiring a service contract negotiation — useful for long-duration deployments where procurement cycles favor a single upfront coverage decision.

Integration and Compatibility

The BP48VP2U02 is explicitly compatible with the following CyberPower PR-series UPS models: PR1500ERTXL2U, PR2200ERTXL2U, and PR3000ERTXL2U (per manufacturer specification). It is also designed for use with the PR1500RTXL2U, PR2000RTXL2U, PR2200RTXL2U, and PR3000RTXL2U. Verify your specific UPS model number before ordering — CyberPower maintains a full power and UPS lineup across multiple battery voltage configurations (24 VDC through 240 VDC), and selecting the wrong battery voltage module will result in a non-functional pairing. This module is the 48 VDC variant; do not substitute a 24 VDC or 36 VDC module for the PR-series systems listed above. Multiple BP48VP2U02 modules can be daisy-chained to further extend runtime — consult your UPS documentation for the maximum number of external battery modules supported per chassis. For deployment planning alongside broader power protection infrastructure, review the full range of extended battery modules and power protection accessories to ensure runtime targets are met across all critical loads.

Frequently Asked Questions

Q: Which UPS models is the BP48VP2U02 compatible with?

A: The BP48VP2U02 is compatible with the CyberPower PR1500RTXL2U, PR2000RTXL2U, PR2200RTXL2U, PR3000RTXL2U, PR1500ERTXL2U, PR2200ERTXL2U, and PR3000ERTXL2U. Always verify your UPS model number before ordering — this is a 48 VDC module and is not interchangeable with CyberPower battery packs at other voltages (24 V, 36 V, etc.).

Q: Can the batteries be replaced without shutting down the connected UPS?

A: Yes. The BP48VP2U02 supports hot-swappable, user-replaceable batteries, meaning battery replacement can be performed without powering down the UPS or the connected load. The replacement cartridge is the RB1290X4J (two cartridges required per module).

Q: What is the warranty on the BP48VP2U02?

A: CyberPower provides a 3-year limited warranty on the BP48VP2U02. An optional extended warranty (WEXT5YR-BP1) is available to extend coverage to 5 years.

Q: How long does it take to fully recharge the BP48VP2U02 after a discharge?

A: Typical recharge time is 6 hours from a full discharge. The module includes a built-in charger, so no external charging equipment is required.

Q: What are the safety certifications for the BP48VP2U02?

A: The BP48VP2U02 carries CE, RCM, UL1778, cUL, FCC Class B, VCCI certifications, and is RoHS compliant. UL1778 is the specific standard for uninterruptible power supply equipment.

Q: How much rack space does the BP48VP2U02 require?

A: The BP48VP2U02 occupies 2U of rack space. Physical dimensions are 17.1 × 3.4 × 19.7 inches (W × H × D), and the unit weighs 66.2 lb. Plan rack load capacity accordingly — the shipping weight is 80.4 lb.

The BP48VP2U02 is one of those modules that only gets evaluated at procurement time when someone finally runs the runtime math — eight 12 V / 9 Ah VRLA cells producing 48 VDC at 70 A is a meaningful battery string, and the hot-swap design means you're not scheduling a maintenance window every time a cell reaches end-of-life. That matters in practice more than the runtime numbers on the spec sheet.

Technical Highlights:

• 70 A Circuit Breaker: The integrated 70 A breaker protects both the battery module and the connected UPS from fault currents — in a shared rack with multiple loads, this is the difference between a contained fault and cascading damage to adjacent equipment.
• 6-Hour Recharge, Built-in Charger: No external charge controller needed; the module self-manages. At 6 hours from full depletion, you're back to full protection capacity before most second-day power events in storm-prone regions.
• UL1778 / cUL Certification: For commercial facility deployments where the AHJ or insurance carrier requires listed equipment, UL1778 on the battery module — not just the UPS — is often the line item that gets questioned during inspection. This module has it.

Deployment Considerations:

• At 66.2 lb, the BP48VP2U02 needs to land on a rack shelf rated for that load — and you'll want two people on the install. Shipping weight is 80.4 lb, so factor that into freight and handling logistics for remote site deployments.
• VRLA batteries degrade faster above 25°C; the rated upper limit is 40°C, but sustained operation at the top of that range will shorten cell life below the 3-year warranty window. If your rack ambient runs hot, address cooling before deploying additional battery modules.

This module is the right fit for a server closet or edge network stack protecting PR2200RTXL2U or PR3000RTXL2U systems in a facility where utility power is unreliable and a controlled shutdown is not an acceptable failure mode — healthcare, municipal infrastructure, or 24/7 light manufacturing come to mind.
