Lithium ion adopted by the high safety performance, lithium battery cathode material for lithium iron phosphate, high stability, high cycle life, high specific energy, specific power, low temperature performance is superior, but large current charge and discharge, at the same time, using suitable for communication demand special high performance
battery management system (BMS), with the charge, over discharge, short circuit, over-current (load), temperature, flow, total pressure protection, balanced and various protective functions. This type of battery is very efficient of backup power supply for the development of high-tech products, with integration, miniaturization, light, intelligent, standardized, environmental protection and other characteristics, can be widely used in indoor distribution stations, integrated base stations, marginal stations, distributed power supply and other fields.
