Help me with my dual coils.

[DesmondTheMoonbear]

Now that I've started building dual coils in my IGO-L, I can't seem to get my builds above .4 ohms! barely okay for my 18650's and not even close to okay for my 18350's. I'm using twisted 28g kanthal at about 5 wraps on each coil and right now it's coming out to .2 ohms. The other day, I did a build with 2 28g untwisted coils at about 14 wraps each and it came out to 3 ohms. what's going on? How can I get this right?

you need to come up in wire gauge, usualy even single coils in 28 are pretty low i use 28 with 4/5 wraps for around .8 ohms. then you have it twisted which is half of the normal resistance. then using dual coils is half again so pretty low.

might be something wrong with your meter. I have dual coils and 8 turn nano coils and it is about .6 ohms. my single coils at 6 turns are .6 ohms.

Just did a dual 12 wrap Nano dragon setup that came out to .6 ohms. The heat and throat hit are lame now, guess I'm gonna have to get myself some Panasonic 30A batteries and head back down to .2-.3

if you are using a twisted pair of wires 28 ga. kanthal there's your problem. The pipe for the current is effectively 14 ga. kanthal, and you are not going to get the ohms up. Using twisted pair wires is a method of halving your resistance and that's what you are doing and why it's so very low.

Go with a single wire.

I just built a dual coil on my Nimbus. .28 ga kanthal, 11 wraps around a 3/32 drill bit. 1 ohm exactly.
