The 20Ah Lifepo4 Battery adopts excellent core lithium iron phosphate battery, with high capacity and low internal resistance. It can discharge at high current without memory effect and can be used for charging and discharging at any time. It has stable performance and long cycle life. After 2000 consecutive charges and discharges, the battery capacity is not less than 70% of the rated capacity. 

Moreover, the 20Ah Lifepo4 Battery adopts high intelligent protection circuit design, to prevent the battery from being overcharged, over-discharged, over-heated short circuit and other phenomena. After the battery short circuit, PTC internal safety switch will automatically disconnect. When the internal pressure is too high, the explosion-proof valve will automatically burst open to prevent explosion. 

In addition, this 20Ah Lifepo4 Battery does not contain harmful substances such as mercury, aluminium and partition. The certification fully meets the environmental protection requirements of European and American markets. It is the first choice for hybrid power, pure power, electric vehicle, UPS, power tools, power storage system and starting power supply.
