With over 20 years of expertise, RackBattery provides reliable, customizable, and cost-effective solutions that meet international safety standards like UL, CE, and IEC.
What Is a 48V Rack Mount Battery?
A 48V rack mount battery is a lithium-ion battery designed for use in standard 19-inch server racks, typically within a 3U or 4U height. These batteries are made of 15-16 LiFePO4 cells connected in series, providing a nominal voltage of 48V or 51.2V. The batteries are known for their high capacity, often reaching up to 100Ah, making them ideal for commercial use in sectors like telecom, renewable energy, and uninterruptible power supplies (UPS). RackBattery’s offerings are modular, space-efficient, and scalable to fit the energy storage needs of any business.
These batteries are often favored over traditional lead-acid batteries due to their superior energy density, longer lifespan, and safer chemistry. In addition, the advanced Battery Management System (BMS) from RackBattery ensures features such as overcharge protection, cell balancing, and temperature monitoring, making them a reliable choice for energy storage applications worldwide.

| BMS Cycles | 6000+ | 4000-5000 |
| Certifications | UL1973, CE, IEC | UL, CE |
| Parallel Units | 16 max | 10-15 |
| Price (Wholesale) | Competitive OEM | Higher retail |
How Does a 48V Rack Mount Battery Work?
A 48V rack mount battery functions through the use of LiFePO4 cells arranged in a series-parallel configuration, which are managed by an intelligent BMS that regulates voltage, current, and temperature. This setup allows the battery to store energy from solar inverters or the electrical grid, which it then discharges as needed for backup power.
RackBattery’s BMS ensures the battery operates safely by preventing overcharge (above 58.4V) and over-discharge (below 40V), while also protecting against short circuits. This system guarantees the longevity of the battery, providing an operational lifespan of over 10 years. Furthermore, the BMS supports active cell balancing, which optimizes the battery’s performance and extends its cycle life.
In terms of connectivity, RackBattery’s batteries support CAN/RS485/RS232 communication protocols, ensuring compatibility with popular inverters like Victron and Growatt, making them ideal for high-demand applications such as renewable energy storage.
