I have 2 questions. My first question is would it be better with a mech mod and a rda to build low ohm builds with more wraps, but less diameter (10 wraps 2.5mm diameter) or less wraps, but more diameter (5 wraps, 3.5mm diameter) Also, I was checking my voltage drop on my mech mod and noticed it was about .2-.5 volts drop. I just cleaned it too. I think I might have to invest in a new mech mod, unless someone can recommend a box under about $30 that could produce enough watts for an rda. Thank you.

Hey Jonathan, depends what your into. i.e are you a flavour chaser or a cloud chaser. also to help more info is required. what wire are using? what wick? which rda? and so on.
0.2-0.5volts voltage drop is not bad actually. You really don't have to build to the max lowest limit a battery can handle, anything below 0.2ohms there really isn't much gain that I have ever noticed, maybe a 1/10th percent more cloud per 0.1ohm you go down. At about 0.3 to 0.4ohms your biggest gain is to build more surface area, wick properly, optimize your airflow, air vortexing in the top cap. I can build a triple parallel 28awg 3.0mm that will out fog someone using a 4.0mm 20awg all day long, less ramp up time. I'm one of the adamant ones that believe below 0.2ohms you are just playing a pointless game with a tempermental fire breathing dragon, the dragon your battery.
I have 26g and 32g Clapton, 24g kanthal, and 26g kanthal. The wire I am using is 24g kanthal. My wick is just organic Japanese cotton, and my RDA is a big dripper clone, mech mod is a fuhatten skyline, and battery is a lg hg2
A larger internal diameter is simply a way of getting more wire into the coil for a given space between the posts. However this increase in diameter can also cause space issues. I find 2.5 mm to optimal for 95% of my builds. Use steam-engine to model your coils and you will see the relationship more clearly.
Voltage drop is directly related to the resistance of the coils, the lower the resistance the more voltage drop you will get. This means it is not absolute, but build specific and is generally only useful when comparing the performance of one mech to another using the same atomizer. A large part of the voltage drop is also caused by battery sag which is also affected by how low the resistance is. What mech and what battery are you using?
"Enough watts for an RDA.."
Entirely dependent on what build you put in it and what you want to achieve. There are plenty of boxes for that price point. If you give some more information about what your requirements are then we can suggest some.

I agree with IMFire, 0.2 - 0.5 voltage drop is not bad at all. You might get a little less voltage drop with a direct-battery mechanical, but I'm not about to recommend one of those to a newer vaper for safety reasons. IMHO, what little gain in less voltage drop you could achieve is outweighed by an increased safety risk. Not worth the risk. This is quite literally the exact setup that we have seen blow up in the hands of uninformed users time after time.
"Enough watts for a RDA" depends upon your battery choice (and its continuous discharge rate, or amp limit), the number of batteries within the mod, and the amp limit of the processor. The RX200, a 200-watt 3-battery regulated mod, can be purchased for around $40 if you look around hard enough. Plus, you'll have the protection circuitry of a regulated mod...something you don't get with a mech.
Doable with the right batteries, but for the love of god why would you want to? Yes you could build a coil that could potentially absorb that much power, but it would not out perform a more modest setup by a margin that would make the endeavor feasible.
I really don't know why you would want to take it that far, but I am sure some people do. For me, it is way more than I will need. I like to run my TFV4 at about 80-120w. Really, anything past 150w is more than I will ever use. I guess it is more the idea of "It is nice to know I could if I ever wanted to." Sort of like having my sportbike that never sees track duty anymore. Yeah, it can go 0-60 in no time and get up around 160, but I never do it. It is nice to know I could if I ever get the itch to go there, though.
