How is this for my first coil?

Is it the fewer the wraps the fewer the ohms?

If you have to ask that you shouldn't be messing around with coils to go in a Lithium ion battery.

It's not the wraps that determine the ohms.
The longer the length of wire the higher the ohms
The thinner the wire the higher the ohms.



ohms is the resistance of the wire to the flow of power; a thin long tube has resists flow;

Think of it like a garden hose. The thicker the hose the better flow of water, the thinner the hose the less of flow of water.

Yould always test your coils before you fire them, especially on a mech. I won't fire a rebuilt PT2 head before using it on the MVP before I check it on a meter. And I most definately won't fire a RDA on a mech without checking it on a meter. People often talk about batteries blowing up in faces because you went too low in ohms for that particular battery, which should be taken seriously, but its those damn hard shorts that you really have to worry about.

So do I have to use a meter before using a RDA on my MVP?

No, you can hook it up the MVP to read the ohms... Just don't fire it before hand.

Thanks for all this great advice!!!!

Well, what did it come out to?? Lol...

Guessing its 2.4 onwards. I'm always getting 2.3 on a 2mm silica with 32 gauge and 6/5 wraps

It looks ok but would be much better if you could check the ohms before actually firing it as there could be short from installing it on your RDA or RBA

Why does everyone seem to think a $10-$20 multimeter is a waste of time and money. I believe $30,000 to $100,000 of plastic surgery and the related recovery time due to an unchecked coil a much bigger waste of time and money (not to mention the negative publicity for vaping)

That's what I told my friend when we were teenagers about quality potato gun material. It was a good thing his parents had wonderful health insurance, otherwise he still would not have a cheek.

Nice garden hose metaphor! exactly how it first was explained to me. Your coil looks nice, but looks and safety are two different things. Since you're using the 32g wire you will have a higher resistance, do that same build with 28 and it would cut your resistance down by more than half. 28,30,and 32 are the most used sizes of Kanthal a1 and the resistances are:

28-5.27 ohms/ft
30-8.36 ohm/ft
32-13.1 ohms/ft

But I doubt you are using feet of kanthal to build your coils so i would opt for an ohm meter because it i hard to measure resistance any other way.

1.9 ohms. Sorry for taking so long to reply.

I was reading through this thread to make sure I wasn't going to post the same thing, but you got it before I did.
