Rack-Mounted Lithium Batteries for Servers

With the rapid development of the digital economy, servers serve as the core carrier of data centers, cloud computing, and enterprise IT infrastructure. Their stable operation relies on reliable power supply. Featuring “high energy density, long cycle life, modular design, and high safety controllability”, rack-mounted lithium batteries are gradually replacing traditional lead-acid batteries and becoming the mainstream choice for backup power and energy storage systems in servers and data centers.

As a world-leading industrial lithium battery manufacturer, Redway Power’s rack-mounted LiFePO4 battery series integrates robust technology and strict quality control. It perfectly meets the core demands of server scenarios, delivering efficient, safe and sustainable power support for critical computing infrastructure.

I. Rack-Mounted Lithium Batteries: An Innovative Choice for Server Power Systems

Servers require power supplies that are “stable, efficient, safe, low-maintenance, and cost-effective”. Although traditional lead-acid batteries have a low upfront cost, they have obvious drawbacks: their energy density is only 30–50Wh/kg with bulky and heavy structures that occupy valuable cabinet space. They offer merely 500–1000 charge cycles and need replacement every 2–3 years, resulting in high maintenance costs. Additionally, lead and sulfuric acid materials cause environmental pollution, failing to meet the development trend of green data centers.

Rack-mounted lithium batteries (mainly LiFePO4 chemistry) perfectly solve these pain points and stand as the optimal solution for server applications:
“High Energy Density & Space Saving”
With an energy density of 150–250Wh/kg, they are only 1/3 to 1/2 the volume and over 50% lighter than lead-acid batteries of the same capacity. Designed in 2U–5U slim form factors compatible with standard 19-inch server racks, they can be flexibly installed in cabinet vacant positions without occupying core computing space.

“Long Cycle Life & Lower Total Lifecycle Cost”
LiFePO4 features stable chemical properties. At 80% Depth of Discharge (DOD), it achieves 5,000–10,000 charge cycles with a service life of over 7–10 years — 5 to 10 times longer than lead-acid batteries. It greatly reduces replacement frequency and maintenance costs, cutting the overall lifecycle cost by more than 40%.

“High Charge-Discharge Efficiency for Dynamic Server Loads”
It achieves 95%–97% charge-discharge efficiency and supports 1C–2C high-rate charging and discharging. It quickly responds to server startup, peak loads and power outage backup, ensuring seamless power switching to prevent data loss and equipment damage.

“Eco-Friendly & Safe for Data Center Compliance”
Free of lead and heavy metal pollution with high recyclability. LiFePO4 boasts excellent thermal stability with low flammability and explosion risks. Equipped with an intelligent Battery Management System (BMS), it provides multi-level protection against overcharge, overdischarge, short circuit, overheating and overcurrent, fully adapting to the 24/7 safe operation requirements of computer rooms.
