Discharge and charge rate for lithium battery is the multiple between the current and the capacity, its unit is C. for example, if the lithium ion battery has a capacity of 800mAh, and its discharging current is 1600mA, then its discharge rate is 2 C rate, if its charging current is 800Ma, then its charging rate is 1 C, normal lithium ion battery and Li polymer battery can work with 1C charging and 2C discharging. Benzo high rate lipo battery can work with at most 60C discharge, our High rate battery can have worldwide advanced 10C charging rate. the indication of being fully charged.
