How Does the Eaton 5PX 48V Battery Module Enhance UPS Runtime?
The Eaton 5PX 48V External Battery Module connects seamlessly to compatible UPS systems, adding additional battery strings to prolong backup power during outages. By supporting up to four external modules (depending on the UPS model), it enables runtime scalability from minutes to hours, ensuring uninterrupted operations for servers, networks, and IoT devices.
This scalability is particularly valuable for organizations with dynamic power needs. For example, a hospital using 5PX 3000i UPS units can start with one battery module for basic server backup and later add three more to cover MRI machines and emergency lighting. The system’s intelligent load balancing automatically redistributes power based on priority devices, while adaptive charging algorithms extend battery life by preventing overcharging. Field tests show runtime increases of 300-400% when using four modules with lithium-ion batteries compared to standalone UPS configurations.
| UPS Model | Max External Modules | Runtime Extension |
|---|---|---|
| 5PX 2200i | 2 modules | Up to 2 hours |
| 5PX 3000i | 3 modules | Up to 4.5 hours |
| 5PX 5000i | 4 modules | Up to 8 hours |
What Are the Key Specifications of the Eaton 5PX 48V Battery Enclosure?
The module operates at 48V DC, supports both lithium-ion and VRLA batteries, and offers a modular design for easy expansion. It features a compact 2U/3U rack-mountable form factor, hot-swappable battery trays, and temperature sensors for optimal performance. Compatibility with Eaton’s Intelligent Power Software allows remote monitoring of voltage, runtime, and battery health.

Which UPS Systems Are Compatible with the Eaton 5PX 48V Battery Module?
The module is designed for Eaton 5PX UPS models, including the 5PX 2200i, 3000i, and 5000i. It integrates via a dedicated battery port, ensuring automatic recognition and configuration. Third-party UPS compatibility is limited, as the module relies on Eaton-specific communication protocols for voltage regulation and status updates.
What Are the Long-Term Maintenance Requirements for This Battery Module?
Routine maintenance includes quarterly voltage checks, annual load testing, and firmware updates. Lithium-ion variants require less frequent maintenance than VRLA batteries. Eaton’s Predictive Battery Analytics tool monitors degradation trends, recommending replacements before failures occur. Battery trays should be replaced every 3–5 years, depending on usage cycles.
For VRLA batteries, maintaining proper ventilation is crucial to prevent thermal runaway. Data centers in humid climates should perform monthly terminal cleaning to avoid corrosion. The module’s built-in self-test feature automates 85% of maintenance tasks, generating compliance-ready reports for industries with strict regulatory requirements. Eaton recommends keeping spare battery trays on-site for critical operations, as lead times for specialized lithium-ion cells can extend to 6 weeks during supply chain disruptions.
“The Eaton 5PX 48V External Battery Module is a game-changer for mid-sized data centers,” says a Redway Power Solutions engineer. “Its modularity allows businesses to start small and scale efficiently. The hot-swappable design ensures zero downtime during upgrades, which is critical for industries like healthcare and finance. Pairing it with Eaton’s software transforms reactive power management into a proactive strategy.”
FAQs
- How Many Battery Modules Can Be Connected to a Single Eaton 5PX UPS?
- Up to four Eaton 5PX 48V External Battery Modules can be connected, depending on the UPS model. This configuration multiplies the runtime proportionally to the number of modules.
- Does the Module Support Lithium-Ion and VRLA Batteries Simultaneously?
- No. Each module must be configured for either lithium-ion or VRLA batteries. Mixing chemistries within the same enclosure is not supported due to differing voltage profiles and charging requirements.
- What Is the Average Lifespan of the Eaton 5PX 48V Battery Module?
- Lithium-ion variants last 8–10 years under normal conditions, while VRLA batteries typically require replacement every 3–5 years. Environmental factors like temperature and discharge frequency significantly impact longevity.
