The eGo-C upgrade battery is the newest improvement of Joyetech. Based on the present eGo-C battery with constant voltage output, this upgrade battery has the new function mode----variable voltage output mode. In this mode, the voltage will change as the battery power changes instead of constant 3.3v output. With high voltage, this will give you a better vapor feeling.
