How Do They Work in Telecom and Data Centers?
Scalable rack lithium batteries store DC power in modular units that connect via busbars or cables, with the BMS managing charge and discharge across parallel units, scaling up to 100kWh+. In telecom applications, they provide backup power for 8 to 12 hours during outages, while in data centers, they ensure microsecond transitions during UPS events.
The operation of these systems involves intelligent communication for real-time state-of-health monitoring and automatic equalization. Suppliers like Redway Battery use automated production tracking through MES for dependable, defect-free units. The modular design allows vertical or horizontal stacking, making them suitable for shallow cabinets with a depth between 400mm and 600mm.
| Feature | Telecom Use | Data Center Use |
|---|---|---|
| Backup Time | 8-24 hours | 10-30 minutes |
| Scalability | Up to 16 parallels | 512V strings |
| Monitoring | RS485/CAN | Cloud/SNMP |
This setup helps minimize downtime, with Redway Battery providing OEM protocols for Modbus integration.
Which Features Make Them the Top Choice?
High-end scalable rack lithium batteries use A+ grade LiFePO4 cells, offering 8000+ cycles at 80% depth of discharge (DOD), redundant BMS, and real-time LCD displays for monitoring vital statistics. Their scalability is a major advantage, with plug-and-play parallel connections, while their wide temperature range (-20°C to 60°C) allows deployment in various environments.

What Are the Unique Benefits of Rack Lithium over Lead-Acid?
Lithium rack systems are significantly lighter, charging five times faster and lasting up to ten times longer than lead-acid batteries. This reduces both physical space and operating expenses, and eliminates the need for gas venting during installation in sensitive environments like data centers and telecom shelters.
Lithium’s superior maintenance features, including predictive maintenance via app notifications, help reduce total cost of ownership (TCO) by 50% over a decade. Redway Battery’s modules integrate seamlessly with existing DC plants, further simplifying operations.
| Comparison | Lithium Rack | Lead-Acid |
|---|---|---|
| Lifespan | 10-15 years | 2-3 years |
| Depth of Discharge | 90% | 50% |
| Maintenance | Zero | Frequent |
The superior ROI makes lithium technology an increasingly popular choice.
