Product Overview
FangService partners with green energy storage expert Shuangdeng Co., Ltd. to deliver a full portfolio of communication energy storage lithium battery systems, providing efficient, stable and reliable uninterrupted green power for global telecom operator base stations, central offices and small mobile communication fields. The systems use lithium iron phosphate (LiFePO4) cells with high energy density, high-rate discharge and ultra-long cycle life, making them ideal for backup power in communication and signal systems.
The systems feature a built-in intelligent BMS that accurately monitors SOC and SOH, with over-discharge, over-charge, over-current and temperature protection. Combined with built-in thermal management modules, they ensure stable operation across a wide temperature range, significantly reducing O&M costs at telecom sites.
