Coil build for IPV Mini2

[astronomicals]

Does that look about right? If you cant see its a 30AWG kanthal, quad coil, 3.175 ID, 8 wraps, 0.7ohm.

Based off these numbers. Guessed 20A limit since I couldn't find that spec.


I read that 1.3-1.6 is what I should be going for, but, that contradicts this so called "sweet spot". I really have no desire for quad coils, but, I used them in this configuration to get my desired resistance while having a proper heat flux. Thoughts?

Hello and welcome to the forum. Glad to have you here!

Can't read anything as your charts are too small.

Sorry I can't really see the numbers in your first picture and zooming in only makes it worse. Are you trying to find the "sweet spot" that can take advantage of the full wattage range?

Or are you under the assumption that there is one sweet spot that works for all atomizers?

 

[astronomicals]

Take advantage of full wattage range. The steam engine calculator said the sweet spot was ~0.7 ohms. Really, I just want the best performance. Should I disregard the sweet spot and build it differently?

It is completely going to depend on what you put on top! I have a Lemo built at 0.9 Ohms running at 19 watts on my ipv Mini 2 and it's a terrific vape.

What are you planning to use on it?

A big dripper clone and doge clone from fasttech. Ones an RDTA and the other an RDA (you probably know this). Also waiting on a HOTCIG Kayfun clone.

Whats your build specs?

The .9 ohm build in my Lemo is a 26 gauge, 2.4 mm 8 wrap microcoil.

I have a Ehpro Pontus (similar to the Big Dripper) and multiple RDA's (Mutation X, Plume Veil, Patriot, Trident V2, Caterpillar and Igo W4).

I've got two Kayfun Lite's, they are easy to build and great for flavor but the airflow is wicked tight. What version Kayfun are you getting? 3.1? Lite? V4? If you like the kayfun but want more airflow check out a Lemo!

It looks like I can mimic the heat flux you had with a dual coil, 30AWG, 7 wrap, 2mm (at 18 watts with a faster firing time). I guess I'll just make some coils to perform optimally at various wattages and see what I like best. Im set on 30 AWG cuz thats what I bought and I feel no need to buy a ton of gauges before playing with what I've got.

Maybe I should cancel the KayFun V4 (HOTCIG) and get a the Lemo drop instead. I do prefer good air flow. Ultimately, I want the best flavor and draw.

Thanks for helping me out.

There's what I'm going to start with. A dual and a quad coil probably at the upper end of mw/mm that I should be going for. I'll make a few sets of coils trying to maintain similar specs while dropping the mw/mm (by upping ohms) which should enable me to use more wire and up my surface area. I figure that sounds like a decent approach. Bumping my resistance up in increments of 0.1ohms should land me at 160 mw/mm at 0.9ohms , so, I only need to make 8 sets of wires, or, 24 coils. Hopefully these coils are easy to make. Its looks pretty simple to me. Try wrapping a double helix 1/4 condenser coil and any other coil looks like cake. Anyhow, wire should arrive soon and attys a few days after. Should have coils ready when attys arrive. Just ultrasonic them and put em together. Ill be using shiseido cotton for wicking.

It's all trial and error with rebuildables. What works great in one, sucks in another. Don't overthink it and just have fun. Ours is a quest for flavor, throat hit and vapor!

I don't know what a "double helix condenser coil" is but 30 gauge is pretty springy it will probably give you a run for your money even if you torch it. Keep in mind you can always twist 2 or 3 strands of 30 gauge together to get some thicker, easier to work with wire.

.6 ohm, 3 mm, 5 wrap twisted 30 gauge

For my lemo build I kinda borrowed the aspire Atlantis coil design, not exactlynthe same of course. Single vertical dragon coil with Japanese cotton, 24g 6 1/2 wraps I think, came out about .74 ohms running at 27 watts, mighty tasty!
