Is it the same as the one in this link? If so, it says that it has a normal working voltage of 3.6v to 4.2v, which I take to mean it's an unregulated battery that starts at 4.2v and drops to 3.6v as you're using it, until it needs to be charged. If it's fully charged and you're using a low restance coil, it may just be too much voltage for you. eGo LCD MEGA 1100mAh battery is with the LCD display, 1100mAh manual eGo LCD battery and 5 clicks On/OFF switch
