So.... First of all. STOP!!!! If you don't have a multimeter and have never built a quad-coil, now is not the time to start. This is how you blow up stuff and make the situation worse for all of us. Sub-ohm multi-coils builds can be dangerous if you don't do it right. To get a 1ohm quad coil build, you need 4 4ohm coils. If you build it with 4 1ohm coils you will wind up with a resistance of .25ohms. Which will be pulling almost 17amps and putting out over 70watts. Please buy a multimeter and learn to use ohms law. Unless you are using 30amp green Sony batteries you are overtaxing your battery which can lead to heating/venting/explosions. I'm not saying that you should never build a quad coil because they can be one of the most rewarding vapes. But you should be metering them before you fire them. Make sure that you have good quality batteries and that you are aware of the limits of your batteries.
