I'm quite new to using mods or a RBA and just recently started building my own coils for my IGO-L. I've made a few successful single coils, making new ones to try to improve the quality of vape. Today I tried my first dual coil. Before I continue on that, let me list the two batteries I use in reference to my question.

1. 800mah Clear Leaf, variable voltage/wattage.
2. Tube mod? With a 800mah 3.7v direct current battery (Sorry if I listed that wrong, I honestly don't know how else to describe it and don't know what it is otherwise called)

Moving on. I finished my coils and attached them to the IGO-L and put it in the Clear Leaf (has ohm reader/tester) and it read .7ohm (Wrapped each coil 5 times). Think I was shooting for more around 2ohm but I honestly don't know much about it (Single coils usually end up 1.7-2.1ohm according to the clear leaf). Regardless I figured I would try it out.

Thing that gets me is, on the clear leaf it reads the ohms, but does not fire at all. Now, on my other mod, it works just fine. Heats up quick, burns red from the center going out, taste good, everything. But, why would it work on the direct battery and not the electronic one? Guess I ask to make sure its still safe, maybe the clear leaf doesn't like it, whatever it may be. Don't need any batteries blowing up on me or anything.

Any info would be great, thank you.

Okay, you should really research Ohm's Law and building coils a little more before proceeding. Plenty of places in here and on the web to do that - no doubt others with chime in with specific references.

What you are doing is making an electrical circuit - one that creates a relationship between power, current, and resistance, and it can be dangerous. Batteries can explode. Circuits can be shorted. Tears may be shed. 'nuf said? Don't mean to be a nanny but things like "I honestly don't know much about it" and "regardless I figured I would try it out" get us worried for you. Jumping into duals? Twice as worrying.

With the ohms, if your trying to make 2.0 ohm dual coil,you would need to make 2, 4.0 ohm coils. When you have a dual coil you take the average of the two coil ohms and divide it by the number of coils you have to give you the actual ohms

And your other problem I'm not to sure what your problem is I'm sure someone else will know, what my guess is that the VV/VW mod has a certain limit of watts it can withstand and the volts your using on the mod with a .7 ohm reading would be going over what the mod could handle. I know I used to have a mod that can only withstand 10 watts, so the most I could do was 3.7 volts with a 1.4 ohm coil. Only 10 watts isn't going to make a coil red until like 10-12 seconds of firing, but it still worked well.

Good luck hope this helped!

Hey buddy- I had some issues when i first started too. Papa here gives awesome advice but i think i can point you to a thread i created to help people out also. It was a join issue with me and some of the pro's here on how to do the math for your battery and find out if something is ssafe to fire on your battery. If you dont know already- you can blow a battery up if your ohms are too low for the battery to handle. Think of that mech mod you have as a "Potential Pipe Bomb". Potential because it probably wont be- but could become one if used improperly. Anyway- here you go:

This might help: Click me :)

Most regulated mods won't fire below around 1.2, my SVD has fired a .9 before trying to see if it would and it did. With that being said, using your Mechanical mod that doesn't have any circuitry will fire no matter what. Take in what everyone has to say and read up on the safety precautions before you start going into gnarly sub ohm, like Laz said we don't want to sound like nannies but we all went through it and had to learn a thing or two before jumping right into the mech/RDA/RBA world.

I figured out my question, at least I believe. And thank you for all replies. Thanks Jayyco, that is something I didn't understand and needed to read on how to figure what a dual coil comes out to. Was thinking 2 1-1.3ohms should be 2-2.6 but clearly thats wrong.

As for the problem with the battery I originally wanted to know about, I believe the issue is that the Clear Leaf goes to 11watts with a minimum of 3.3volts. And 3.3 volts with .7ohm is 15.55 watts of power? So, possible it just doesn't even fire cause the minimum volts still totals a higher wattage than the battery safely allows.

Realizing I'm just tired, I see you mentioned that same answer Jayyco and TheReign. Might have been easier if I seen your posts before I went and figured it out but I thank you for your replies. And Nanny away, I've no intention on getting hurt, was just a stupid mistake not reading on dual coils to know how to achieve a set ohm and not calculating how many watts I was actually putting out with that coil, bit higher than I was thinking, won't happen again.
