Key Features of Our High-Density Server Rack LiFePO4 Battery
Our Server Rack Battery is more than just a stack of cells; it’s a culmination of cutting-edge power electronics technology. Each LiFePO4 Server Rack Battery is designed to withstand harsh operating environments.
Ultra-High Energy Density. Our optimized internal structure in standard 3U, 4U, and 5U chassis provides extended home backup power runtime, ideal for space-constrained residential energy storage projects.
Grade A LiFePO4 Chemistry. We insist on using brand-new Grade A LiFePO4 cells, rejecting substandard or salvaged cells. Their exceptional thermal stability eliminates the risk of fire, ensuring worry-free use.
Intelligent Smart BMS. Each rack-mounted battery pack incorporates an industrial-grade intelligent battery management system with active balancing to ensure consistent voltage across cells. Real-time monitoring of voltage, current, temperature, and SOC is available via an LCD screen or PC software.
Massive Scalability & Parallel Support. Our design prioritizes the flexibility of an all-in-one battery pack. Advanced parallel protocols allow you to easily connect up to 15 devices.
Scalable Energy Storage: All-in-one Battery Pack from 5kWh to 50kWh+
Our all-in-one battery pack solution features a highly modular design, designed to allow your battery energy storage system (BESS) to seamlessly upgrade as your electricity demand grows.
Whether your project starts with a basic 5kWh server rack battery or requires building a mid-range energy storage system exceeding 50kWh, our products offer a perfect fit.
- Entry-Level (5kWh – 15kWh): Ideal for residential energy storage, meeting the basic power needs of individual users and apartments, as well as home backup power.
- Mid-Range (20kWh – 40kWh): Suitable for large villas or users with high-power hybrid solar systems, supporting long-term operation of high-power devices such as air conditioners and water heaters.
- Commercial Scale (50kWh+): Provides stable industrial-grade power for small offices, farms, or telecom base stations through parallel connection of multiple server rack battery backups.
What is a Server Rack Battery?
The Server Rack Battery is a Lithium Storage Battery module designed specifically for standard 19-inch server racks. Named for its size resembling that of a data center server, it is a core component in modern Battery Energy Storage Systems (BESS).
Unlike traditional lead-acid batteries, the Server Rack Battery features a highly modular design. It integrates multiple LiFePO4 cells, a smart BMS, and safety protection devices into a compact metal casing, allowing you to expand the system’s energy storage capacity like building blocks.

Stackable lithium battery Applications
Whether you’re a home striving for energy self-sufficiency or an industrial site with stringent power stability requirements, our server rack battery backup provides precise power support.
- Residential energy storage: This is the most widespread application area for stacked lithium batteries. Used in conjunction with a hybrid solar system, it stores excess solar energy during the day for use at night or during peak electricity prices, significantly reducing household electricity bills.
- Critical home backup power: In the event of a power outage due to natural disasters or grid failures, the system can switch to home backup power within milliseconds, ensuring the continued operation of refrigerators, lighting, security systems, and medical equipment.
- Off-grid solar system: In remote areas, islands, or locations without a public power grid, lithium storage batteries are the only energy source.
- Telecommunications & data centers: Provides UPS-level backup power for 5G base stations, micro data centers, and network switching rooms.
- Commercial & industrial: By connecting multiple all-in-one battery packs in parallel, it increases the proportion of green energy used by enterprises, contributing to the achievement of carbon neutrality goals.
