Vertiv AS5B0NCVGNNXLKB Lithium-Ion UPS Battery Module

Overview

The Vertiv AS5B0NCVGNNXLKB is a lithium-ion battery module designed for the APS MAX UPS platform, rated for 10KVA systems with a 15KVA scalable path. Where lead-acid strings demand replacement every 3–5 years and struggle in warm equipment rooms, this LiFePO₄-based module delivers a rated service life of up to 10 years and is designed to hold performance at elevated temperatures rather than derating — a meaningful difference in dense data center rows, telecom cabinets, and industrial control rooms where ambient heat is a constant pressure. The AS5B0NCVGNNXLKB ships as a single battery string weighing approximately 46 lbs, making it manageable for two-person installation without mechanical lifting equipment in most rack environments.

Key Features

• LiFePO₄ Chemistry for Thermal Stability: Lithium Iron Phosphate is chemically the most stable lithium variant — lower risk of thermal runaway compared to NMC or NCA lithium cells. For installations in enclosed cabinets or equipment closets with limited ventilation, that chemistry choice is load-bearing from a safety standpoint, not just a marketing distinction.
• Up to 10-Year Service Life: Doubling or tripling the replacement interval of a typical VRLA string directly cuts lifecycle labor and disposal costs. In a multi-cabinet deployment where battery swaps require scheduled downtime and possibly a maintenance contract, the difference between a 4-year and 10-year battery compounds significantly over the asset life of the UPS.
• Recharge Time Under 4.5 Hours: After a full discharge event — a generator failover, a utility sag that ran long — the module recovers to full capacity in under 4.5 hours. That's the window during which you're exposed if utility power dips again. Faster recharge shortens that exposure window, which matters in regions with unstable grid quality or during storm season.
• Advanced BMS with Cell-Level Monitoring: The onboard Battery Management System monitors at the individual cell level, not just the string aggregate. That granularity means the BMS can isolate a weak cell before it degrades string performance or triggers a false capacity reading in the UPS. It also generates the data needed for predictive maintenance programs — know a cell is drifting before it fails, not after.
• Better Performance in Higher Temperatures: Lead-acid batteries lose roughly 50% of rated capacity when ambient temperature rises from 25°C to 40°C. LiFePO₄ degrades far less steeply across that range. For installations in industrial facilities, rooftop telecom huts, or any space where HVAC is marginal, that thermal tolerance directly translates to retained runtime when you need it most.
• Minimal Maintenance Requirements: No fluid checks, no equalization charges, no corrosion inspection on terminals from outgassing. The reduced maintenance burden lowers the total cost of ownership across a multi-year deployment — particularly relevant in remote or unmanned sites where a service truck roll is expensive.
• 5-Year Manufacturer Warranty Covering UPS and Batteries: A single 5-year warranty covering both the UPS hardware and the battery module simplifies service contract management and eliminates the common scenario where UPS and battery warranties expire on different schedules, creating coverage gaps.
• Approximately 46 lbs per Battery String: At roughly 46 lbs, a single string is within standard two-person lift guidelines for most jurisdictions, reducing the need for mechanical assistance during initial installation or battery replacement. For multi-string configurations, plan the rack layout so strings can be slid in horizontally rather than lifted vertically.

Integration and Compatibility

The AS5B0NCVGNNXLKB is designed for the Vertiv APS MAX UPS platform. Confirm compatibility with your specific APS MAX model and configuration before ordering — lithium battery modules are not universally interchangeable across UPS families, and the BMS communication protocol must match the UPS controller's expectations. If you are evaluating this module as part of a new UPS deployment, consult the APS MAX product documentation for maximum battery string count and cabinet configuration requirements. For environments running parallel UPS systems or extended runtime configurations, verify that your UPS systems installation supports the number of strings required to meet your runtime target at full load. Pair with a managed PDU downstream for outlet-level load monitoring that complements the BMS data from this module. For planning runtime budgets across multiple critical loads, review our UPS runtime planning guide before sizing battery strings.

Frequently Asked Questions

Q: What is the warranty on the AS5B0NCVGNNXLKB?

A: The AS5B0NCVGNNXLKB carries a 5-year manufacturer warranty covering both the UPS and the battery module.

Q: How long does the AS5B0NCVGNNXLKB take to recharge after a full discharge?

A: Recharge time is under 4.5 hours from a full discharge to full capacity.

Q: Why does this module use LiFePO₄ chemistry instead of standard lithium-ion?

A: LiFePO₄ (Lithium Iron Phosphate) is the most thermally stable lithium chemistry, significantly reducing thermal runaway risk compared to NMC or NCA cells. It is the standard choice for UPS and energy storage applications where safety in enclosed spaces is a requirement.

Q: How does the AS5B0NCVGNNXLKB perform in warm environments?

A: The module is rated for better performance at higher temperatures compared to lead-acid alternatives, which can lose substantial capacity as ambient temperature rises. This makes it better suited for industrial, telecom, and other installations where ambient heat is a factor.

Q: What does the Advanced BMS do on this battery module?

A: The onboard Battery Management System monitors at the individual cell level, providing granular visibility into cell health. This enables predictive maintenance — identifying degrading cells before they affect string performance — rather than relying on aggregate voltage readings that can mask early-stage failures.

Q: How heavy is a single battery string for the AS5B0NCVGNNXLKB?

A: Each battery string weighs approximately 46 lbs, which is within standard two-person lift limits for most installations. Multi-string configurations should account for horizontal slide-in rack positioning to avoid overhead lifts.

The spec that changes the conversation on the AS5B0NCVGNNXLKB is the cell-level BMS monitoring. Most battery modules report at the string level — you get an aggregate voltage and a health percentage, and you're flying blind on which cells are actually drifting. Cell-level visibility means you can pull maintenance data, trend it over time, and schedule a replacement before you discover the problem during an actual outage. That's the operational difference between reactive and predictive power infrastructure management.

Technical Highlights:

• LiFePO₄ Chemistry: Thermal stability that matters in real installations — dense telecom rows, industrial control rooms, any space where ventilation is compromised. The AS5B0NCVGNNXLKB won't introduce the same thermal management burden as NMC-based alternatives.
• Sub-4.5-Hour Recharge: Post-event recovery window under 4.5 hours. In grid-unstable regions or during storm events where multiple sags are possible in a 24-hour period, that recovery speed is the difference between being protected for the second event or not.
• 10-Year Service Life: At double or triple the replacement interval of VRLA, the real savings show up in avoided labor and scheduled downtime — especially in remote or hard-to-access installations where a battery swap is a half-day project, not a 30-minute one.

Deployment Considerations:

• Verify BMS communication protocol compatibility with your specific APS MAX controller revision before ordering — lithium modules require active BMS handshaking that VRLA replacements do not, and a mismatch will prevent the UPS from properly reporting battery state.
• At ~46 lbs per string, two-person installation is straightforward for a single string, but multi-string rack configurations require careful sequencing — plan the physical layout before any strings are racked to avoid having to reposition under load.

The AS5B0NCVGNNXLKB is the right call for critical infrastructure deployments — edge data centers, industrial control rooms, unmanned telecom sites — where battery replacement logistics are expensive and thermal environment cannot be fully controlled. The combination of 10-year service life and cell-level BMS intelligence eliminates the two most common failure modes in extended-runtime UPS deployments: unexpected capacity degradation and surprise end-of-life failures.
