SMOK TFV4 TANK - HELP !

Hi guys, i bought smok tfv4 tank last week,
Im using the RBA that was provided in the box and currently im using a single coil, can i make dual coil on the RBA provided? Or i need to buy another deck/rba to make a dual coils.

So far tfv4 was great enough with a single, but i'd like to make a dual coil on RBA if possible. Thanks!

It might be possible if you made them small enough but sacrificing the coil size probably won't do anything as the single coil can already be pretty massive for a tank. If your dead set on the dual you need to buy the dual coil rba.

Thank you sir. How much does the dual coil RBA usually cost?
And whatt's the best setting for the coil? The wraps and kanthal size..
I'm aiming for best cloud with less possible dry hits..thanks!

I believe I got my dual RBA for about $7, check out Vapecrawler.com and look around (remember to factor in shipping).

As far as what to do with the coils. I've tried a bunch, my fav for single was a 4 wrap 24g kanthal as a vertical coil. And for the dual I went with 26g twisted with 5 wraps (about .2 ohms). I run that at 70-95w depending on the juice. Not saying it's the best, but it works well for me (waiting on some new wire to come in to try some other builds).

I wouldn't try to build a dual on the single head. You will have some funky airflow issues. If you want more than what the prebuilt coil it comes with just make your own. And if you go with vertical you can get even more out of it. I'm currently working on modifying the deck to better accomplish that build, I think it's worth it.

Thank you sir! I'll do some research for the shop for the dual coil rba.

Thanks for the recommendations, will try the single build while waiting for my dual rba

Before leaking juice all over, you might want to watch the following video

Good point on wicking.

I don't remember what video it was. But for the horizontal coils this is how I saw to go about it and it works.
Note: I cut my cotton sheets into ~6-8mm strips

1) take the backing off a strip of cotton, and pull about 1/2 of the fluffy inside off the strip (~2-3mm thick)
2) twist one end tight, just enough to let you feed it through your coil.
3) pull it through, there should be slight resistance, but not so much that you're ripping your cotton or tweaking your coil. (at this point I usually pull it back and forth a little bit.
4) pull it to the end leaving enough that it reaches the end of the juice well, then cut an equal length on the other side.
5) repeat if you have a dual coil (for me I use 1 strip for 2 coils)
6) This is the trick here, take the cap and push it down on top, start to twist it on then remove the cap. This leaves small indentations on the cotton right where the cotton reaches the top of the deck, this is your guide.
7) cut the excess cotton at and angle across that indentation, one side at the top(closest to the coil) of the indentation, the other slightly below the indentation.
8) Prime it up and tuck the ends of that angled cut into the juice wells.
9) top it off plug it in, fill your tank and you're off (good idea to close airflow when refilling, and also don't overfill).

For Vertical coil I did it a little different, and I know it's not optimal, but here's how:
1) build your coil, get it set up, then take the strip of cotton and pull the backing along with a little cotton (~1mm of fluff)
2) Start with that strip, you'll leave one end in one juice well and wrap it with the backing on the inside touching your coil. Leave the top longer lead outside the cotton. Wrap it around twice and leave the other end in the opposite juice well.
3) Pull your top lead down and secure it.
4) Done!

Very simple, not optimal, still working on modifying my deck to handle what I want to do with the vertical build (needed bigger lead holes, but it's proving a pain to drill out). I figure if I can get that going well I'll probably add chiminey holes for more juice and wrap more cotton around the outside of the coil to soak that up. All goes well it should be nice.

I got my dual deck for about $7 as an add on with my tank.

So I've posted this in other threads already, but I'm simple ecstatic. Drilled out the holes in the single build allowing me to put in some thicker wire. Went with 3X 24g Kanthal twisted, 5 wraps around 4mm for a .3ohm read. Wicked it how I said above and my god. The flavor, the warmth (but not burning), it's just excellent. Cranked it up to 110 so far and no issues in sight.

It beats out my .2ohm 26g Kanthal dual coil for flavor and density, cloud production about on par. It's just magnificent. The idea that there is something else out there better just seems silly to me at this point. I'm in love. I've only had it running for about an hour now, so we'll see if any hiccups occur, but yeah, this thing is a beauty.

To me it beats out the premade coils, less cloud volume but far more density and flavor which is more to my liking when I'm not just trying to put weird faces on people.

Thought it was worth posting about.
