RDA How close should the resistance of each coil be in a dual coil build?

[ddirtyvapes]

Subject is pretty self-explanatory. I've mostly been doing single builds so far as the one dual set-up I put on my Twisted Messes was just too hot for me.

I know dual coils have to be the same resistance and I understand how the resistance changes versus a single coil set-up. I just want to know if the resistances have to be as exact as humanly possible, or if wrapping the same gauge with the same ID and the same # of wraps is sufficient provided the overall resistance is reading correctly? I'm using a regulated VV/VW device and I did check each coil independently when doing the one dual build but without a second rda yet it's kind of a PiTA.

Any guidance here would be great. Thanks in advance!

Depends on how exact you want your build to be.

You can throw 2 completely different builds on each side and still vape as long as the ohms falls in the safe area for your battery.

You can also be as OCD about it as you want. Just comes down to how you want to vape.

That's pretty much all I needed to know. I was under the impression that putting two different builds on each side was a no-go, though? Did I misunderstand something?

If they are not close they will heat up differently. There is no danger in the coils being different. Unless you build out side of your batteries range.
A 0.5 on left and a 1.0 on the right will get a 0.75 build but it will taste like shyte.

basically MOST of the power from the battery will o to and be used by the coil with the lowest OHM. if they are close together no issue, if they are far appart more issues.

If you want coil that heat differently, but in parallel. Then wrap to the same OHM using different gauges. Or same OHM with varied ID
