Triple coil on a 3 post RDA?

[JT!]

Kind of some noobish questions here.

I'm having a hard time trying to grasp if this would work in my head or not. Would 3 coils work or would I have problems with one side being half the resistance as the other?

Would having 3 coils produce bigger clouds than 2? (Working with 50w max @3.8 volts)

Right now I'm at two but at high wattage I get burnt hits so in my head in makes sense that 3 would allow more juice to get to the coils.

And I'm also thinking 4 might be overkill?

I just can't get my head round this stuff.

It's sounds like your issue is not more coils. Without seeing a pic of your build, it sounds like you have a wicking issue possibly combined with power issue. If you are not wicked properly you will get bad hits. Power, resistance and wicking all have to work together to produce the perfect consistent vape. Post a pic of your build and we can make more educated comments to help you. More coils can produce more vapor but without proper wicking, resistance and power you can still get bad hits. With tri coils your resistance is cut in thirds so to arrive at a .3ohm build, all of your single coils have to be .9ohms. It would make your build even hotter causing bigger wicking problems. If you are torquing your build with 50 watts, everything needs to be properly set up. Your three post atty is designed for singles or dualies. Here is a quad vertical I have been running the last few days. Thing is a Beast.

You could do married/kissing quads, use a larger ID, parallel coils, etc. These are married coils:

The concept is that they're 2 coils (generally per side) that act as one and heat up from the center of the two <-> outwards

Cool build. You should do a quad married[emoji317]

Prebuilt coils that came with the RDA. So no idea the guage. But they total .3ohm according to my subox.

I was maybe thinking 4 coils 8/7 wraps each at 3mm diameter... hopefully should end up with .3ohms if the math is right.

But if I use a triple coil setup i can make them each 6/5 wraps.

Lol I did. I was lazy that morning but I did it after making those and posting that pic.

Ugh mystery China coils...no Bueno. Pick up a 100ft spool of wire, like 26g KA1 or N80, or both, and build some coils. You could parallel 26/26 KA1/N80 & have some type of staged heating since N80 heats quicker. Or build quads. And clip your leads! You'll short out if your leads are touching the other coil or the positive leads are touching the deck.

Done! 26g Kanthal A1. 5/4 turns 0.3ohm (ish)

Was going to do 4 coils with the same wire at 8/7 turns for a little under .3ohms but it was too difficult to fit on 3 posts. I'm happy with this. Can run at the full 50w and not getting those burnt hits with the old coils.

Simple answer is, yes, you can build a triple in a 3 post atty. You can also do it in a 2 post and 1 post atty, assuming you have the space.
