I'm having problem with my batteries or 5 volt box mod cutting off all the time. Even when I'm using mad vape vv box mod it still cut off, so I turn the main power off and then back on it works again for 2 second then the same thing. I'm using 3ohm single coil cart and dual coil 1.6ohm cart from Madvape. I even use five different sets of battery that I use in rotation. Can someone help me PLEASE?
