Vertiv AS4B0NCVGNNXLKB Lithium-Ion UPS Battery Module for APS 10KVA Scalable Systems
Overview
The Vertiv AS4B0NCVGNNXLKB is a lithium-ion battery module engineered for the Vertiv APS 10KVA scalable UPS platform, supporting configurations up to 20KVA in an N+1 redundant topology. Built on LiFePO₄ chemistry, it delivers a rated service life of up to 10 years — roughly double that of conventional VRLA alternatives — making it the right call for data centers, edge deployments, and power protection installations where battery swap cycles carry real downtime risk and labor cost. If you're evaluating Vertiv UPS and power systems for a multi-year deployment, this module is designed to outlast the typical refresh cycle.
Key Features
- LiFePO₄ Chemistry: Lithium iron phosphate is the thermally stable end of the lithium-ion spectrum. It resists thermal runaway far better than NMC or NCA chemistries — a meaningful safety distinction in enclosed equipment rooms and edge cabinets where venting options are limited.
- Up to 10-Year Service Life: With a rated service life matching a typical data center refresh cycle, this module eliminates the mid-cycle battery replacement that VRLA-based uninterruptible power supplies typically require at years 3–5. That's one fewer maintenance window, one fewer truckroll, one fewer planned outage.
- Sub-4.5-Hour Recharge: Full recharge in under 4.5 hours means the system returns to protected status quickly after a discharge event — relevant in environments with repeated short outages or utility instability where back-to-back events are a real scenario.
- ~46 lbs Per Battery String: At roughly 46 pounds per string, this module is lighter than equivalent VRLA battery sets, reducing structural load on raised-floor tiles and simplifying hot-aisle/cold-aisle cabinet planning. Verify your floor loading specs, but this is a favorable number for dense deployments.
- Advanced BMS with Cell-Level Monitoring: The onboard battery management system tracks individual cell state — not just aggregate string voltage. This matters because a single degraded cell in a VRLA string often goes undetected until the string fails under load. Cell-level visibility enables proactive replacement before a capacity event.
- Better Performance at Higher Ambient Temperatures: VRLA batteries derate significantly above 25°C; lithium-ion chemistry tolerates higher ambient temps with less capacity loss. For edge sites, telecom shelters, or any deployment where cooling is intermittent, this translates to more reliable runtime when conditions are least ideal.
- Minimal Maintenance Profile: No fluid checks, no equalization charges, no periodic capacity testing required at the same frequency as VRLA. Maintenance burden is low — a practical advantage across distributed deployments managed by lean IT teams.
- 5-Year Warranty (UPS + Batteries): The 5-year manufacturer warranty covers both the UPS and the battery module. Battery warranty coverage is often the weakest point in UPS procurement — having it bundled and co-termed with the UPS simplifies vendor accountability.
Integration and Compatibility
The AS4B0NCVGNNXLKB is designed for the Vertiv APS 10KVA platform in scalable N+1 configurations up to 20KVA. Verify chassis compatibility with Vertiv's configuration documentation before ordering — battery module form factors are platform-specific. Pair with compatible network infrastructure monitoring tools that support SNMP or Modbus for runtime visibility across distributed sites.
Frequently Asked Questions
Q: What is the warranty on the AS4B0NCVGNNXLKB?
A: Vertiv provides a 5-year manufacturer warranty covering both the UPS unit and the battery module.
Q: How long does the AS4B0NCVGNNXLKB battery take to recharge after a discharge event?
A: The module recharges in under 4.5 hours under standard conditions.
Q: Why choose lithium-ion over VRLA for this UPS application?
A: LiFePO₄ lithium-ion offers up to 10 years of service life versus 3–5 years for VRLA, performs better at higher ambient temperatures, weighs less per string (~46 lbs), and requires minimal maintenance — all factors that reduce total cost of ownership in multi-site or long-lifecycle deployments.
Q: Is the AS4B0NCVGNNXLKB safe for use in enclosed equipment rooms?
A: LiFePO₄ chemistry provides significantly better thermal stability than other lithium-ion chemistries, reducing thermal runaway risk. The advanced BMS provides cell-level monitoring to detect degradation early. Always follow Vertiv's installation guidelines for ventilation and spacing requirements.
Q: What UPS platform is the AS4B0NCVGNNXLKB compatible with?
A: This module is designed for the Vertiv APS 10KVA scalable UPS platform, supporting N+1 configurations up to 20KVA. Confirm chassis compatibility with Vertiv's current configuration documentation before ordering.
The spec I keep coming back to on the AS4B0NCVGNNXLKB is the cell-level BMS monitoring — most lithium UPS modules report at the string level, which still leaves you exposed to a single bad cell dragging down runtime before any alarm fires. Cell-level visibility is what separates a proactive maintenance posture from a reactive one on mission-critical power.
Technical Highlights:
- 10-Year Service Life: Rated up to a decade versus 3–5 years for VRLA — in a 20KVA N+1 stack, eliminating one mid-cycle battery replacement set can easily offset the lithium premium when you factor in labor, logistics, and planned downtime.
- Sub-4.5-Hour Recharge: Back to full protection in under 4.5 hours after discharge. In environments with utility instability — grid-edge deployments, older buildings with frequent momentary outages — fast recovery is not a nice-to-have; it's load protection continuity.
- ~46 lbs Per String: Lighter than equivalent VRLA string capacity. In raised-floor data centers, this matters for tile load ratings and also for the two-person install requirement — lighter strings mean more deployment flexibility in constrained spaces.
Deployment Considerations:
- LiFePO₄ performs better than VRLA at elevated ambient temps, but it still has thermal limits — confirm the equipment room's sustained temperature range against Vertiv's published operating envelope before spec'ing this for an uncooled edge site.
- Platform compatibility is not universal: this module is specific to the APS 10KVA scalable chassis. Do not assume interoperability with other Vertiv UPS lines without verifying the configuration guide — mixing battery module generations is a common field error.
Best fit: distributed enterprise edge deployments — branch offices, retail backrooms, remote comms shelters — where a 5-year warranty, low maintenance burden, and 10-year service life align with a single-generation infrastructure plan and lean on-site IT support.
