Hi guys...thanks for the time checking my post...

Just a quick question. Im using RX200, im trying to build my own coil using clapton kanthal 26g. LG HG2 batts. I want to be on the safe side so im looking to build a coil around .4-.3ohms, i've read its unsafe going too low specially for someone who isn't an expert mech mod user.

I know that i'm using a regulated mod and all i need to do is enter 30-50w and it will pretty much do the rest for me, ill always use wattage mode, but im someone who is paranoid about safety so
Im trying to understand and vent out any info on how can the ohm meter and ohm calculator keep me hypothetically extra safe even with a regulated mod.

Can any vape expert or veteran give me solid points and actual value samples?

Thanks in advance!

Hi @dlcountpau,

At the extremes of the values you've listed (.3 ohms @ 50w), that needs 12.91 amps at 3.873 volts. I'd say that you're safe as long as the battery is charged and in good condition.

I'm by no means a battery expert. However, @Mooch is! I'd recommend searching out his posts (and reddits). They contain very valuable information on batteries!

Hope this helps!

First, stop worrying, you'll be 100% ok.

You have 3 batteries in series, meaning a theoretical 12.6v (realistic 11.1v, 4.2v theoretical for each battery, 3.7v realistic due to sag and system losses).

You'll have 20amps to work with on the intake.

Now these regulated mods will convert voltage to amperage, so they have an input limit and an output limit. Anyways, .3Ω coil at 50w will need 3.8v, and it'll then pull ~13amps, that's just doing the math (Voltage/Resistance = Amperage, and Wattage = Amperage * Voltage).

So you're 7 amps below what your batteries can handle, using only a tad over what a single battery will give you for voltage, and basically you're as safe as safe can be using one of these things. Your danger is the same as leaving the house, if a freak accident happens that's the only way you'll have an issue. Get hit by a car, or have that setup cause you harm, I'd put money on the car hitting you first.

Anyways, make sure to secure everything correctly, tightening the screws down on the atomizer all the way (if it reads higher resistance than you expect i means something is loose, lower and it means something is shorting, or touching that shouldn't).

Regulated mods have a serious safety buffer between the battery getting dumb assed and going all super fucky in your face... It is the chip.

You could and not suggesting it, push that mod and batteries full throttle. worst the mod will take the brunt of the damage if any, Best case it just does not allow you to push it to the point of failure.

I always need to see the Ohm formula. Not sure why but I just get fumbled a bit on doing formulas like that. Good to have it handy to look at as a map. * copies to a text file called Ohms, appropriately *

The amount of napkins/postit notes I have with ohms law formulas scribbled on it is a bit crazy. W*Ω=V² and the like I can never remember, but I can remember the bases, just have to do a bit of...algebra...:blech:

This is assuming you're using reasonable batteries of course (you wouldn't believe what some people think is a suitable battery for a box mod):D
They said they're using HG2s. Should be good, though Jon did mention once that they're being cloned so might be something to watch for.

Exactly. I used to be able to do the maths as long as someone walked me through a problem, prompting the "how do you find X?" Hell, we did trigonometry in our welding class at our local vo-tech during high school. Our instructor tricked us. "You fools, come in the classroom a bit." "See that blueprint? Figure out how much material is needed, then, figure out where the welds need to be to maintain X psi for steam based upon the volume of Y, also define which material would be best suited and why."

We all got rather busy and focused in on what we had to do. Started finishing up he started talking again. "You guys say you are worthless and got no brains. I just proved you all wrong. You've just been doing some of the most advanced maths there is, trigonometry. You didn't even know you were doing it but you were." We nearly took the plasma cutter to him but he just laughed. "You're all far better than something so petty. Think of a way to confound me as torture instead."

Finally we come up with it. Shaving cream liberally applied to the urinal flush handle. :) Damned if he wasn't puzzled over how to flush. Hehe.

Wouldn't this just be a little easier http://www.steam-engine.org/batt.asp?b=LG_18650HG2&mah=3000&c=6.666666666666667

I do build around .3 to .4 all the time on my RX250. Just make sure your batteries have a good charge and you should be good to go. I wouldnt go below .25 or so unless you really know what you are doing.

Just throwing this out there as with the 250w update on the RX200 it becomes a concern. Ohms law comes into play for safety. Generally regulated mods are quite carefree, and if you're not going crazy on wattage it's just not a concern. But, for the RX200 when you go above 200w you have to make sure you're building low, sounds crazy I know, but the point is you're closing in on max voltage. So you want to be say below .32Ω for 250w (that's how the math works out and how they recommend on their website, props to them for taking the time to advise that). Generally though you only need to question things when moving towards the limit of your regulated mod. A single battery mod at 75w you want to question, 2 battery at 150w again question (though many of these will actually cut you off before hand, especially say the cuboid), and 3 batteries I'd question anything over 200w and take the time to do the math. That said most newer or inexperienced users won't be touching 200w any time soon, Hell I know what I'm doing and I still haven't had a build where 200w suited me best, 150w yes, 200w no. But, I got a few new RDAs which might change that (all my previous RDAs are mini's and in general RDAs I use at much higher wattage than tanks with similar builds as the wicking is much better).

Anyways, not all that relevant, but worth mentioning.

Me personally I never go above like 80 watts. In fact I am usually hanging around the 40-60 watt range. I dont think there will ever be a situation where I need more than 80 watts. I am about to start building claptons tho and I know they require more power but I seriously doubt for me that I will need much more than that.

I think it is quite relevant, and thank you for presenting it. Information like this is a blessing to those coming on in vaping. I had wondered myself why the higher end little box mods hitting 75 watts needed such low sub ohm coils. Now, I can comprehend why that is the case. I will file it under all the other useless junk in my brain's attic tool chest. I have a recipe for a pie with 3 points and a one 4 or something in there. :)

Make sure you post your build bro. Always nice to look at some sweet claptons!

Nice man. I got a big wire order coming in on Tuesday and I will try my first claptons. I have already perfected twisted wire. Cant wait to try claptons!

Nice! I havent tried twisted yet. Post some pics of your build :)

Still workin on the best way to clapton wire but these are vaping nicely.

You gotta try fused Claptons now they work so much better and about the same difficulty to build actually I think fused Claptons might even be easier . Then you gotta try ss fused Claptons lol
