Im new to vaping. I have a Joyetech Evic Vtc Mini with Cubis tank. Im changing from the tron tank to the cubis tank. Im using the cubis 0.5 ohms coil. Do I need to do anything to the settings when i put the cubis tank on? Will it recognize the new tank and coil automatically? Do i use power mode with this coil and stay under 25 watts still? Any help would greatly be appreciated
