Parallel coil= My Lips!

[Vesuvius]

Did my first parallel coil. About burned my damn lip off. Did 26g, 4 wraps, 2mm ID. Read .27
Ramp up was instant which I liked. A ton of vapor but, mouth piece got very hot after 2 vapes.
Maybe its a little to much for an Igo L. The air hole is already drilled out just a little above 2mm. I am loving the parallel though. Maybe I can try and get it closer to the air hole and aim a little higher on the ohm's. Maybe .5 or .6.

Now I am wondering how dual parallel's would be on my Igo W Plus.

What mg nic do you vape on it?

what were you vaping on before this build and rda?

6mg nic. Last build was single .5ohm 24g Kanthal. I only own 2 RDA's. An Igo L and the Igo W Plus.
I think I just had the parallel sitting to high in the cap and the air flow was not really hitting it. Im going to do another after work. Going to try and get the coil right on the air hole and see if it helps.

If it still gets too hot, I will just do another parallel but closer to .5 or so.

Ah right, i thought you might have come to the rda world from a tank type system like a ce4 etc, i was gonna say that you would need to lower your nic lvl if so...

Not enough airflow or to small an rda for your build will also give you burnt lips...

But yeah try your idea and let us know how it go's

Yeah, gotta keep each coil close as possible to its air inlet. Your draw has to force air directly into the coil to compensate for its heat output. No direct airflow means it just keeps getting hotter and hotter until eventually the atty itself will get piping hot. This is true no matter how you play around with battery output / coil resistance. 2x coils (of same type) means 2x heat dissipation is required....

Stock airflow on those RDAs are...on the very low end of low. It's good to hear the air holes have been widened. But the IGO-L only has one air hole, which means you can realistically only put one coil in it... Since it seems you are open to modding, maybe put the cap in a vise and drill through the existing air hole to the other side, to make a second air hole?

I haven't had much luck cooling coils by putting them near the drip tip. Air tends to take the most direct / least resistant path, which means in that case airflow will go diagonally from inlet to outlet, so it will really only pass directly over the very top of a coil mounted near the drip tip, not against the middle of the coil.

Its a lot better. I added 2 more wraps so 6 wraps, this time at 2.4mm. Reading .5. Also brought it down and closer to the air hole as possible. Works good now.

The Igo L cap is on the small side also. I am thinking about a second hole but, was thinking about putting it right next to the other one. I think the Igo L is a decent RDA but, I think its limit is going to low with the ohms. It just seems to trap heat real easy with its small profile.

Thinking maybe I will just keep the Igo L the way it is and just get an RDA that is more suited for pushing the ohms.

Oh, my mistake. By parallel coil I thought you meant putting one regular coil on one side of the posts and a second regular coil on the other side, so they'd be electrically in parallel, i.e. ( [:] ) That's why I had suggested a second air inlet opposite the original.

I'd look for an RDA that has deep/wide juice well(s) and fully independent posts, something really easy to build on. I've bought too many novelty/hyped attys; each has its own problems, and have thought many times it'd be better to toss out the lot for 2-3 really good ones.
