RDA How do I figure out a watt range?

[vapenoob22]

I just got my first rda and built a dual coil build that comes out to .35 ohms. I'm all about pushing it as far as I can go so what other information do I need to figure out the watt range?

I know on pre-made sub ohm tank coils they typically have a range for them so I am thinking there's some way to determine this for rdas pretty easily for various builds?

My personal rule of thumb is whatever the wattage is at 3.7 volts. With a .35ohm coil that would be 40 watts or 39.114 Watts to be exact.

Would the reason for that be because of the certain batteries and the amount of batteries you are using? I know that plays a factor into all of this... I'm just trying to figure out how to calculate it.

You can get a ohm calculator for your smart phone. You can go higher on your wattage depending on your personal preference. My reason is that's basically the wattage I would get on my mech mod. Start at 40 watts and go up a little or down until you get the taste you like.

It's Ohm's law. Ohms Law Calculator

So if I am running 3 18650 LG HG2's what would my amps be? 60 since each is rated for 20 amps? That would mean I could run a wattage theoretically safely until the calculation went over 60? or 20?

I reread your question and have edited my post.
On a regulated mod the resistance of the coil is essentially unimportant. Start with low wattage and increase it until its good for you and your taste, there is no specific correct wattage.

don't worry about calculating anything. just start low and increase until its how you like it. and no do not run your mod to 60 amps. most likley your device has some kind of amp limit in it. but even if you tried you would just get burnt hits.

Yes just start low increase until you like it.

Ohm alone tale us just one part of the systems. A general rules of tumbs is the more metal you have the higer the wattage you should go to heat up all this metal. Since you can lower ohm by putting less wrap = less metal or putting more thing in parallel = more metal. A quad coil fuse clapton at 0.35 ohm usualy require much more wattage than a simple single coil at 0.35 ohm since the former has much more metal and surface to heat up.
