　　The polymer lithium ion battery’s features:
　　A. High energy density
　　The special energy of polymer lithium ion battery can reach 380～400Wh/L.

　　B. High voltage
　　A single lithium ion cell has a voltage of 3.7V ( mean value).

　　C. Pollution-free
　　The lithium ion battery does not contain any polluting substances such as cadmium, lead, mercury, etc.

　　D. Non-metal lithium
　　The lithium ion battery does not employ any lithium metal. It is not governed by aircraft transportation rules relating to carrying lithium batteries in passenger airplanes.

　　E. Long cycle life
　　Under normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cycles.

　　F.No memory effect
　　The lithium ion battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.

　　

　　G. Fast charge capacity
　　The lithium ion battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell.
