Cylindrical LiFePO4 is a kind of rechargeable batteries with high theoretical capacity, excellent cycle life (about 2000 times) and good performance at high temperature (about 70 celsius degree), and it has the trends to be applied in Hybrid Electric Vehicles, E-Bikes and GPS tracker, Medical devices etc electronic products for the safety factors. Melasta LiFePO4 Batteries' capacity can be range from 40mAh to 12000mAh, and the discharge rate from about 1C to 20C, like IFR18650 1,100mAh 20C drain and IFR26650 2200mAh 20C drain. And our factory also produce prismatic polymer LiFePO4 battery now, such as LFP80120125 3.3V 10000mAh and LFP8870170 3.3V 9Ah.
