WERAN WRL-48100RW 51.2V 100Ah LiFePO4 Rack Battery (5.12kWh) – 8000 Cycles, CAN/RS485, Stackable Home ESS

WERAN WRL-48100RW is a 51.2V 100Ah (5.12kWh) rack-mounted LiFePO4 battery designed for reliable home solar storage and small ESS projects. Built with brand-new LFP prismatic cells (no second-life cells) and an intelligent BMS, it delivers long service life with 8000 cycles @80% DOD. The battery supports CAN/RS485/RS232 communication and scalable installation up to 12 units, making it easy to expand capacity as energy demand grows. With high efficiency (99% @25°C/0.5C), natural convection cooling, and optional features such as single-pack aerosol fire suppression, heating function, and Bluetooth, WRL-48100RW is a practical 48V-class battery solution for inverter-compatible residential ESS and distributed energy storage.
