3.2V500mAhLiFePO4 Battery Pack 14500 Cylindrical
3.2V 500mAh (1.6Wh) cylindrical 14500 LiFePO4 Battery
Max dimension: 14 X 50.5 mm
Max continuous charge current: 0.5 A (1C rate)
Max continuous discharge current: 2.5A ( 5C rate)
Peak discharge current: 4A (8C rate)
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.
