The FJ48100 is a standard rack-mounted low-voltage energy storage lithium battery with a single-module capacity of 5.22 kWh, built on LFP/102Ah cells and supporting flexible series-parallel expansion. It integrates easily into storage cabinets or UPS systems, providing reliable, scalable modular storage for telecom base stations, microgrids or residential battery walls. With a wide 44.8–58.4V range compatible with 48V systems, intelligent BMS monitoring over CAN/RS485, and parallel support for 2–10 units, it scales cleanly from 5.22 kWh up to 20.88 kWh.
