So i have a SmokX Cube2 with an Ijust 2 tank, NI200 .15 ohm coil. When i hook it to my cube, i have temp set to 420F coefiecent is at .006 mode is normal. For some reason i am gettin almost no vapor, and a slight burnt taste. it hits its set temp in about 1.5 seconds. and displays a temp protected message. can anyone explain what i am doing wrong. My batteries are half full ( if that could be the issue). Just need help.
