In the modern digital age, data centers and server facilities demand unprecedented levels of efficiency and reliability from power solutions. Especially in the context of global energy shortages and the trend towards green energy, traditional lead-acid batteries are gradually being phased out, and high-performance lithium batteries have become the core alternative and upgrade option. As a leader in the industry, the internationally renowned brand ONESUN (Wanshun Energy) offers its flagship product – the 48V 100Ah server rack battery – providing global customers with top-tier rack battery solutions to help businesses achieve energy upgrades and stable operation.
Since its inception, ONESUN has consistently focused on the research and development and manufacturing of lithium-ion energy storage systems and battery products. Leveraging years of industry experience and a global perspective, ONESUN not only strictly controls the selection of basic battery materials but also continuously innovates in overall design and system integration. This demonstrates its rich product line and technical strength, proving its outstanding position and product competitiveness in the energy storage industry.
Core Product: 48V 100Ah Server Rack Battery
ONESUN's 48V 100Ah server rack battery is an ideal energy storage solution tailored for high-reliability scenarios such as data centers, server rooms, telecommunication base stations, and UPS applications. This battery uses LiFePO4 (lithium iron phosphate) cells, which are widely recognized in the industry for their high safety, long cycle life, and excellent thermal stability. LiFePO4 cells inherently possess excellent thermal stability and a high safety threshold, and the overall battery design has been deeply optimized to meet the demanding requirements of rack-mounted applications.
The product features a standard 19-inch rack design, with a compact size and easy installation, meeting the standard requirements of server rooms and cabinets. The modular design also supports parallel expansion, allowing for flexible connection of multiple battery units to expand energy storage capacity according to load requirements. This scalability enables ONESUN's rack batteries to meet the energy needs of businesses of varying sizes, from small enterprises to large data centers, truly achieving on-demand customization and flexible deployment.
