51.2V 100Ah LifePO4 Rack Mounted Battery

The WT5100 51.2V 100Ah rack battery is designed for dependable energy storage in residential backup, solar power, and off-grid applications. With 5.12kWh capacity, 6000+ cycle life, and integrated BMS protection, it delivers stable performance for both daily energy use and standby power needs. Its rack-mounted design supports clean system integration, while parallel expansion capability makes it easier to build larger storage systems as power demand grows.

Built for flexible system expansion, this battery supports up to 63 units in parallel, delivering a maximum storage capacity of 315kWh. This scalable design makes it well suited for projects that require higher energy capacity, including residential backup clusters, commercial energy storage, and other applications with growing power demand. As energy needs increase, the system can be expanded more efficiently without changing the overall installation architecture.

A built-in 100A Battery Management System helps protect the WT5100 at every stage of operation. The BMS manages key safety parameters including voltage, current, short-circuit response, and temperature protection for safer and more stable energy storage performance.

It features 3.65V cell over-charge protection, 58.2V module charge protection, 2.5V cell over-discharge protection, and 40.2V module discharge protection. The system also includes over-current protection above 99A / 110A during charging and above 99A / 130A during discharging, with short-circuit protection above 260A. Charging temperature protection is activated below 23°F or above 149°F, while discharge temperature protection is activated below -4°F or above 158°F.

The WT5100 supports convenient battery monitoring through the front display and app connectivity, making it easier to view system status during daily operation. Users can check key battery information such as voltage, current, and operating status more efficiently, helping improve visibility and control in energy storage applications. The system also supports RS232 / RS485 communication for PC software and CAN / RS485 for inverter integration, providing flexible connectivity for different installation needs.

The WT5100 features a compact rack-mounted design that helps simplify installation, system layout, and future expansion. Measuring 18.98 × 20.08 × 5.43 inches and weighing 101.4 lbs, it is designed for clean integration into cabinet energy storage systems, making it a practical choice for scalable power projects.
