I have been looking around and haven't been able to find a difinitve answer. I am assuming that with the rba 2.0 on a Grand you have to use a 3.7v 18650 battery? Is it possible to use 6v if you keep the ohm's around 2.5-3.0?

I run a 2.0-2.3 ohm coil @ 6v in my RM2 on a Reo mini

Since I cannot find a carto ohm meter available anywhere right now, is there a basic rule of thumb of how many wraps of wire will work on the rba 2.0 without frying your mod? Does the number of wraps change with the different size gauge of wire? I am going to get a RBA but I do not want to fry it.
the carto meters are mainly for convenience. you can use the $5 meter from Harbor Freight or any meter from Radio Shack, Lowes or HD.
any one them will help prevent frying things. it's pretty easy to wrap a coil that should be 1 ohm or 2 0hms or whatever based on wire guage and number of wraps, but one tiny thing out of place can cause a short.
darn near everyone who has wrapped coils has had that happen. ya never know until you measure it -- or fry something.
Yes, the thicker the wire (lower the gauge) the lower the resistance the coil will be with the same wraps. The inside diameter of the coil will also have an effect. The smaller the ID of the coil, the less resistance. If you space out the wraps rather than wrap / squeeze them so they touch, the resistance will be higher (more wire = more resistance).
Using a 1/16" mold like a drill bit and 10 touching wraps of 30 ga is a great starting point. More wraps = higher resistance = cooler vape, less wraps = lower resistance = warmer vape
Thanks for the info, I appreciate it. I saw a thread the other day where people had listed the wire gauge, number of wraps and what size diameter wrap and it gave the corresponding ohms, but for the life of me I cannot find it.

but you still need a meter

Day late and dollar short again!
Since my RM2 is on its way, I have a question for the experts.....
I have been vaping at 6v with 3.0 ohm regular resistance cartos for almost 3 years now. I have stuck with 6v because of the huge throat hit, lung hit, outstanding flavor and much stronger nic hit versus 3.7v. My question is, if I wrap a 1.0-1.5ohm micro coil and use the 18650 battery, how does that compare to vaping at 6v? I am hoping the RM2 is a leap forward and not backwards.

6 volts with a 3 ohm carto is 12 watts....3.7 volts with a 1 ohm RDA build is 13.69 watts. So pretty similar heat output I would think. I have never vaped at 6 volts, but with the advent of rebuildables I have not had much push to try it.
I am sure this has been mentioned before but I am really surprised at how much just a small change in the setup of a RM2 can effect the vape. Mine was hitting a little harsh with my 2.2 ohm coil (even running it at 3.4 volts). Was actually starting to ponder drilling the hole out when it hit me that perhaps just changing the drip tip might help. Put on a shorter one with a much larger inside diameter hole and the harshness vanished. So I am thinking that the drip tip change altered the turbulence inside. That got me to thinking why the manufacturer decided to start making one post taller than the other. Tilts the coil to change the turbulence characteristics?
Funny you say that. I use a wide mouth drip tip and always tilt my coil so it's higher above the juice hole . Good observations bro

Well actually mine is one of those that the post on the right is much higher than the other, like about an 8th of an inch or more. Seems a very deliberate way to alter the air flow coming through the vent hole. Instead of the air hitting the middle of the coil dead on. Tilting the coil would pass the air under it creating a swirling effect in the chamber?
Anyways... I understand Zen has been playing around with turbulence dynamics with their atty so wondering if that is whats up with the taller post.

Interesting... Do you have a specific reason for tilting the coil that way? I'm planning to get an RM2, so it seems I have 86 pages to read in the coming days... In the meantime, how high off the deck do you usually keep your coils at? Thanks!
