HB -40℃ Low Temperature Lithium Battery, 21.6V 5Ah 18650 Low Temperature Lithium Ion Battery
Overview&Features
Special lithium batteries are lithium batteries with special characteristics, such as high temperature resistance, low temperature resistance, fast charging, fast discharge, high voltage, high energy density, etc. Special lithium batteries can be used in aerospace, missile-borne vehicle equipment, military weapons , Polar scientific research, frigid zone rescue, power communications, public security, medical electronics, railways, military electronics and other industries.
Special lithium batteries must be specially customized. The difference between them and ordinary civilian batteries is that they have a faster charging speed, a wider operating temperature range, a higher low-temperature discharge rate, and a better explosion-proof function.
