Lithium ion (Li-ion) batteries are designed to feature a high energy density, a high capacity, a light weight and a high power. The voltage of the cylindrical type is 3.7V; and the voltage of the button type is 3.6V.
Lithium ion Polymer (LiPo) batteries employ Li-ion electrolytes and is packed with an aluminium plastic film. It has a high energy density and are safer than any other type of Li-ion battery.
