About to do first coil build and have some questions.

[AustinNelson]

Hey there, I just started vaping about a month ago using RTAs but I figured I would order the Mutation X V3 and try out an rda.

I ordered 22 gauge Kanthal A1 wire with some organic cotton. I have an IPV Mini 2, which is capable of .2 ohms, and Samsung INR18650-25R batteries with max 20A discharge. I was wondering what would be the best build? I am gonna do a dual micro coil but I'm not sure on how many wraps I should do to stay above that .2 ohm resistance. I will be getting a mechanical mod here soon but I am deciding on which one to get.

Help would be appreciated

start with building the coil or coils on steamengine.

For what it's worth I would do the first few build at about the same power levels yo are using NOW.

There is N O room for error at .2ohms and is not a good place to learn. At .2 a .1 error could DAMAGE your device. also your battery is only "safe" to .3ohm, Personally I'd stop at .5ohm.

22 gauge is a pretty heavy wire.... its gonna take alot of heat to get it up to working condition ( long preheat) and it will hold that heat long after you let off the button( cook thehellouta your wick)... consider 26 gauge... heats up quicker and cools quicker.. I prefer 28...

First and for most, if your new don't start with 22 gauge. I wouldn't recommend it. Start with 28 or 30 to be honest. Never run 20amp batteries below a .5 build. 28 guage 6 wraps dual coils on like a 3mm drill bit/screw driver will get u about .6-.7 if I remember. A .2 is going to be a hot vape for a new person and is not good on some 20amp batteries. Battery safety is very important. Any questions feel free to ask.

And unfortunately I'm going also reiterate what those above me said, profusely. Plus keep in mind that pushing your regulated mod to its lowest resistance will also hugely impact that battery life if you so choose to do it.

Sorry it isn't that I just agree with them its more of a precaution if anything. I will add you have taken a good step in the right direction for the fact your using a regulated mod instead of utilizing a mech mod.

Even at .22 ohms you would be leaving very little headroom. Ideally, you would want to give your battery around 20-50% headroom. I'm strictly speaking of only the battery at 4.2v. .26-.27 ohms is the bare minimum that I would comfortably go to with 25R's.

I second 26-28 gauge kanthal.

Edit...ignore this didnt see the 25 amps. Still pushing it though



unning a .3 coil on a 20amp battery is asking for trouble. Just saying... iv vented 3 batteries and not proud of it but I have done some stupid things and have learned A LOT.

And Stay Above .5 ohms for your first build.
Good Luck

Also - get an ohm meter if you don't already have one. Checking your builds for shorts is good practice before putting them on your regulated mod and possibly frying the electronics or putting them on a mech mod and shorting the battery.

SOOOOOO Totally agree with the 22gauge being too much for a beginner. Go for 28gauge, then try some twisted and parallels.

Kanthal A1
gauge ----- watt per ohm (per coil) for 200mW/mm2
34 ----- 1.4
32 ----- 3
30 ----- 6
28 ----- 10
26 ----- 23
24 ----- 45
22 ----- 91
20 ----- 182

22 gauge needs about 100 watts per ohm.

and about 10 volts per ohm.

The advice to use an ohm meter is very solid... things can go wrong quickly at .2 ohms.
