How many watts maximum with this setup?

Well the Sigelei will put out 100 watts safely with those batteries in it. As for the dual coils, it all depends what you're mounting them in, if you wick them correctly, what gauge wire you used and how much air flow you have on the coils.
I'm using kanthal 26, 5 wraps each coil, get a total read of 0.2 ohm. I am testing it, stopped at 25 watts since I am not sure and wanted some input on this. Thanks.
ops, japanese cotton wick, and Smok caterpiller dripper, full air intake.

Should be able to safely use as much as the coil and wick will take, which all depends on you. Go up until it either suits your tastes or burns. If it burns, back it off and rewick it. Just don't lung hit while you're doing that. Lol
ETA: fwiw, I'm currently running a .3ohm 24awg kanthal 11/10 wrap single parallel coil at 90 watts. Started at 50 and slowly increased. No burn yet, and I'll prolly push it a little further to see if I can get to 100w, just for giggles. Lol

You've got a lot of air flow with that RDA. IMO you won't make it past 50 watts because of the 26 gauge wire at 0.2 ohms. I would make sure the wicks are wet and as Spidey said, try increasing the power in say 5 watt steps until you are happy with the vape or you get a slightly burnt hit. If you get a burnt hit, back down a bit and that will be the most power you'll be able to use.
I'm curious how high you can go so please let us know what happens. Make sure the air holes are all open and centered on the coils.

Yup, that setup has a lot of coil surface area. I don't know what RDA you've got, but I bet it's still a good vape at 100 watts.
FYI you have a VERY powerful device. You do not need to build that low, in fact its not very smart considering the amp loads you require. Yes you are protected but its hard on your equipment. Why not build to .50 or .70 and use the 7.4 volts available instead of messing around with 4.
Rant over, I guess turn it up until the heat is too uncomfortable then turn it down till it is. Thats what I do but I only have 60w devices which is plenty.
Oh almost forgot, even a VTC5 is only a 20amp continuous discharge battery not the advertised 30. Kidney puncher has the test data. Build higher and do some high voltage vaping your results will be just as good.

For sure you can probably hit 88W. Maybe higher. I vape my 0.4 ohm Orchid build at 44W.
You were absolutely right. At 40w it was perfect, nice and warm. At 45w it had an slight burnt taste so i lowered it at 40w again and think that is the sweet spot of it.
BTW, if I wanted to raise wattage what would I need to do? Smaller gauge kanthal like 24? And how many ohms to look for?
Thank you.
You're welcome and thanks for letting me know how it went. It's nice to see I'm on the right track.
I modeled your setup in the Steam Engine coil wrapping calculator. Here it is at 40 watts. You can see your coil details entered and on the right side under 'Results' the heat flux number at 40 watts is 443 mW/mm² (miliwatts/square mm of coil surface area). I vape in that area and I know it's good with typical RDA air flow. Change the heat flux watts to 50 and the number increases to 553 mW/mm². I thought that was going to be too much power per coil surface area and it would burn juice.
If you want to increase the power, increase coil surface area by either using a lower gauge, thicker wire at the same resistance, or increase the resistance with the same gauge wire by adding another wrap to the coil. Or a combination of the two. Here is the setup at 0.5 ohms with 26 gauge wire and 100 watts. The coil has gotten longer and the number of wraps have increased. You can use a bigger pin to wrap on and that will bring down the number of wraps and keep the same resistance and heat flux. Heat flux is 443 mW/mm² at 100 watts, so it should be a good vape. I don't think it will do much at 40 watts though
It's a really neat calculator. You can change the wire gauge, the resistance, check out parallel builds, twisted builds, multiple coils, etc and see what happens to the results. Also, if the heat capacity goes too high for the power applied you'll start to notice coil heat up time increase.

Coil resistance has no bearing on amp draw in a regulated, VW mod such as the Sigelei 100. Coil resistance only determines output voltage.

That calculator seems to be what I needed. Back to coil making now. Thanks a lot Ryedan, awesome help!
