Im a newbie to RDA's I been vaping for a year on my variable voltage Kanger Pro 2 and 3. I have on the way an H Cigar RDA
And was planning on running it with my S1000 Mech Mod
But it doesnt have any voltage or ohm adjustment so I was thinking of upgrading to something better, for now im thinking of running a dual dragon nano coil, just looking for a cloud monster.
Suggestions?
Good idea of getting an RDA with a mech mod. Take everyone's advice and get some good 30a batteries like those Sony VT4's. This is what I've found out:
1.2 ohm+ coils are better for VV/VW devices, since they up the voltage to match the coils. a 2.4 ohm clearomizer works horrible on a mech mod.. it's like putting your vv/vw on 3.7 volts...
at 1.2 and under, that's mech mod range, since it can draw more wattage from the battery than most VV/VW mods can handle.
Getting an ohm meter is a must have. Also,
Ohms law calculator is a must.. bookmark it.
To get your desired vapor, aim for what WATTAGE you want for each coil. The thicker the wire, the more wattage you'll want to heat it. Use Ohms law calculator to decide what ohms to get the desired wattage and determine if the amp limit is too high.
I know, it sounds confusing, but let me give you one example.
Let's say I've used 32 gague kanthal coil at 2.1 ohms in my genesis and I like the flavor at 8 watts. plug 2.1 ohms and 8 watts into the calculator, hit calculate, and it states I am using roughly 4 volts of electricity and 1.95 amps. modest numbers, but it is actually what I am vaping at this very moment.
Now, I want a similar vape out of my dual coil nimbus and my mechanical mod. I have a freshly charged 20 amp battery that just came off the charger. Batteries usually start at 4.2 volts, so I will be using that as my base. my goal is 8 watts per coil for two coils. Since the power will be distributed evenly to each coil, you would double it for the calculator so it shows 16 watts. So, I'd plug in 16 watts, 4.2 volts into the calculator and hit calculate. It shows that I need 1.1 ohms resistance to get those numbers. So, I'd have to double that number and make each coil 2.2 ohms resistance. It would only draw 3.8 amps of battery, so I am safe for that build....
Now, I want to chase clouds. I bought some 26 gague kanthal and wish to push the limits. I set a limit of half the battery (say I have a 30a battery) so I want to use 15 amps. The battery fully charged is 4.2 volts, so I plug in those two numbers... It comes up with .28 ohms of resistance using 63 watts. That means to do dual coils, that's a .56 ohm coil and each coil would get a whopping 31.5 watts... that's some serious power to those coils.

I'm still under half the amp draw limit of the battery, so I'm fairly safe with that build with the right battery.
If none of this makes sense, then you'll need to do some more research. If you have a VV/VW mod, you could experiment getting a single coil dripper, and see what you like for dripping. I'd also experiment with stainless steel mesh on a vV/VW device as well, since those have their own faults.
