LiFePO4 Power Tool Rechargeable Batteries 12V 16Ah For Solar Product
Lithium iron phosphate has gradually become a research hotspot of power batteries in recent years. It has the advantages of high safety, good cycle performance, green environmental protection and low price. Disadvantages are: low voltage platform, low tap density, low current, low temperature discharge. It has become a bottleneck restricting the commercialization of lithium iron phosphate. Recent studies have made great breakthroughs in low temperature performance and rate current. The lithium iron phosphate produced by Mitsui Co., Ltd. can charge and discharge at a maximum rate of 20C, and the capacity of charging and discharging at a 3C rate of 500 times is maintained at 90% or more.
