方形磷酸铁锂
Square lithium iron phosphate (LiFePO4) battery
LiFePO4, short for Lithium Iron Phosphate, is also called LFP. Due to its high energy density, light weight and better safety performance, lithium iron phosphate batteries have been widely used in many applications, from small to small consumer equipment to heavy industrial machinery.
Why choose lithium iron phosphate?
These batteries have deep cycle capabilities, so they are particularly suitable for energy storage solutions (ESS) and heavy machinery. Fengyun Battery can help provide renewable energy storage solutions, and design and manufacture portable energy solutions.
Square lithium iron phosphate battery
Due to its very stable structure, these batteries are usually mainly used for industrial and household use, UPS applications, telecommunications, golf carts, and energy storage for electric vehicles. The capacity of a single cell can be 20Ah-120Ah.
