Rack lithium batteries, especially LiFePO4 models from experienced Chinese manufacturers like Redway Battery, provide high-performance backup for UPS systems. Designed for 19-inch server racks, they deliver rapid recharge, long cycle life, and advanced safety features. Redway Battery’s OEM solutions offer scalable voltages, intelligent BMS integration, and global support, making them ideal for data centers, telecom, and industrial applications seeking reliable, efficient power.
What Are Rack Lithium Batteries?
Rack lithium batteries are modular 19-inch LiFePO4 units designed for UPS and server cabinet integration. They replace traditional lead-acid packs with lighter, longer-lasting solutions supporting 4000–6000+ cycles at 80% depth of discharge.
Redway Battery manufactures these batteries with ISO 9001-certified facilities, ensuring robust thermal management, CAN/RS485 communication, and scalable voltage outputs from 48V to 691V. Modular design allows parallel expansion for higher capacity, and wholesale buyers can access OEM customization for industrial needs.

How Do Rack Lithium Batteries Work with UPS?
Rack lithium batteries connect to UPS systems through a DC bus, while the BMS monitors voltage, state-of-charge, and fault status. They provide immediate backup during outages and recharge in 1–2 hours.
Redway Battery optimizes UPS integration with flexible wiring, black-start capability, and support for low- and high-voltage ranges.
| Feature | Lead-Acid UPS Batteries | Rack Lithium (Redway OEM) |
|---|---|---|
| Cycle Life | 500–1000 cycles | 6000+ cycles |
| Weight | Baseline | 50–70% lighter |
| Charge Time | 8–12 hours | 1.5 hours |
| Operating Temp | 0–40°C | -20–60°C |
This demonstrates how Redway Battery reduces total cost of ownership by 40–60% for B2B applications.
What Makes Them Compatible with UPS Systems?
Compatibility is ensured by the 19-inch rack form factor, adjustable voltage outputs, and intelligent BMS that matches UPS charge profiles. LiFePO4 chemistry avoids voltage sag and maintains runtime.
Redway Battery customizes racks for UPS brands with dual-redundancy protections, low-temperature operation, and scalable energy capacities from 5–50 kWh.
