hot mod

[trapdaddy]

I am fairly new to vaping, and I have a Stingray Mod with a Stillare dripper (18650). I recently changed from 6 coils to 4 coils, now the mod is getting hot all the way down to the switch, before I can get finished with the first application of juice. What could be causing this? Coils are not touching anything, both are evenly spaced inside of the atty, and both coils are burning evenly, from the center out, with no hot spots. It should be burning a little cooler with 4 coils vs 6, correct?

You say six then four then both. I assume you are talking about six wraps and four wraps on a dual coil setup. It sounds very much as if the resistance on those new coils is too low for the battery you are using. Less coils - less resistance - more heat - more power drawn. Stop. Go purchase an ohm meter. Know your resistance and whether you have a short before pressing the button. Once you know your resistance go here http://www.steam-engine.org/ohm.asp.
Set the volts to 4.2 and the ohms to your resistance. Look at the current section to see how many amps you are drawing. Check your specs on the battery you are using in particular the amp rating. Don't build coils that exceed that rating in current draw. This stuff can be dangerous if you don't spend some time learning first. Please be safe. Until you get the equipment and knowledge I suggest you go to your local brick and mortar vape shop and have them build it for you.
You will pick it up quickly I'm sure but until then li-ion batteries are dangerous when put under too much stress.

Less wire (lower coil count) means lower resistance and more heat.

If you don't have an ohms meter, you should get one so you know what you're building. Too low of a resistance could be dangerous if your battery is a low end one and not up to the task.

Heat from the button is also different from heat from the atomizer. If your button is getting hot its time (past time) to disassemble the button and polish all of the pieces to remove corrosion. Same with the top cap and it's threads.

So, What should be a safe ohm level for 18650 20Amp (30Amp pulse) 3.7v 2500mah

If you play with the calculator that lefty linked for you, safe for a Li-** chemistry battery is 75% of constant amp capability.
So 15a gets you to a 0.28 ohms build. Do people go below that, sure. People push limits all the time but that doesn't mean it is "safe".
