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.

Fengyun square LiFePO4 battery characteristics

Shenzhen Fengyun Battery Co., Ltd. is one of the main manufacturers and suppliers of LiFePO4 batteries in China . Our batteries have many advantages, thanks to our superior technology and the most advanced manufacturing equipment, as well as a large investment in research and development.

1. Extremely long service life

Fengyun LiFePO4 battery has a long service life due to its excellent performance and reliable quality. In a temperature environment of 25°C and a depth of discharge of 80% , the product can provide at least 2500 lifetimes.

2. Lighter weight

Compared with lead-acid batteries and all other old technology batteries, LiFePO4 batteries are very light. Due to this characteristic, these batteries are popular batteries in the electric vehicle industry, and their performance is better than lead-acid batteries.

3. Environmental protection

Fengyun Battery uses high-quality materials to produce batteries. These LiFePO4 batteries do not contain any harmful substances, so they are completely environmentally friendly and recyclable batteries.

4. Wide temperature range -10℃ to 60℃

工作温度范围非常宽,可在极端温度下工作使用。正常工作温度范围是-10℃+ 60℃。这些电池在极冷的温度下也可用作启动电池。

5.较低的内阻

这些电池的内阻非常低,这对其安全性非常有利。它可按需提供大电流,并将电池温度保持在正常水平。

6.免维护                      

通常,旧技术电池(例如铅酸电池)需要定期维护,这会增加电池系统的额外成本。磷酸铁锂电池可以像铅酸电池并提供免维护的解决方案。
