Do I measue my current resistance with cotton and everything? Or just coils because that's how I've been measuring :eek:

Either way... resistance shouldn't really change in that case. Wicks and juice have nothing to do with your resistance.

Would ypu recommend since I still am learning that i stay around a .10? I obviously did not understand that the atty was not compatible. The people at my local vape
Shops just have pretty faces so I've had about 3 days in person learning from my brother in law and the rest online

I'd recommend that you stay above 1 ohm.
More importantly I'd recommend that you use a regulated mod so that you have SHORT CIRCUIT PROTECTION.

If you use a mechanical mod, you should not use one without a centerpin like the SMPL unless you have the knowledge to use it; it depends on the atty having a protruding centerpin.

I switched the atty to my mutation v4 is that alright? This is the first time I've ever had something like this happen and I'm just trying to understand it more.
i use my mutation vx4 on mine but you must still visually inspect your atty for coil shorts and for the correct center pin , the smpl mod is not a good mod for a new user at all I always suggest if you start with a mech to use something with top and bottom contacts to avoid the problem with the 510

My mutation when i built it was at .12 i just measured now its at .28
You probably have loose screws after the coils heated it's common but another thing that mucst be checked after you dry fire and then again after you wick it to make sure you don't push your coils into your posts if you tug on them at all during wicking

You don’t say which samsung battery so I’ll assume you’re using the best / highest CDR 2500mah battery they offer, which is a 20a CDR battery.
4.2v / .09Ω = 46.6a - you're drawing 26.6 amps more than the battery can safely handle.
Even as the battery voltage drops you are still dangerously over stressing the battery.
3.2v / .09Ω = 35.5a
2.8v / .09Ω = 31a

Your math is off, always use the fully charged voltage of 4.2v for calculations.

Most folks leave a % of amps under the battery’s CDR as headroom for safety.

I would not go any lower in resistance than .3Ω using a 20a battery.

I think before you start messing with mech mods, you have to understand the relationships between resistance, voltage, current and power.

Here's an Ohm's law calculator. There are tons of them all over the internet.
http://www.ohmslawcalculator.com/ohms-law-calculator

A 0.5 Ohm build at 4.2 volts will draw 8.4 amps and produce a little more than 35 Watts. If your battery can handle at least 10 amps continuously, that should be OK (as long as the battery doesn't short to the bottom of the atty). That might be a good place to start until you get more experience with it.

Also a hybrid top cap mod is about the worst for a beginner just trying to get going. You might consider getting a mod with a 510 pin so you don't have to worry about that issue for now. You've got enough to think about at first. ;)

Help a lady out!

The outside threads on the connector of your RDA are part of a circuit that should never contact the top of your battery. A regular mod will prevent that, a hybrid, like the SMPL will not. The center pin in the middle of that thread, SHOULD be insulated from the outside threading, and in the case of a hybrid ABSOLUTELY MUST hang down below the outside threading, and STAY below no matter how tightly you screw the RDA (or whatever) into that mod.

I agree that it is nuts for your vape shop to have sold you a hybrid. I've been doing this for over 3 years, and I wouldn't dare mess with a hybrid.

You can put a vapesafe fuse in it to help protect you, but they trip at 7 amps, and your builds are too low ohm for that. So your choices, budget wise, are to get a fuse and build higher ohm builds, or get rid of that SMPL and get a safer mod. You obviously have an ohm meter that will detect a short in your build, so you don't necessarily need a regulated device. But since you seem to be going after cloud chasing builds, you can get something like a Pioneer4you D2 for about $35, and you will have a very safe, regulated mod that includes temperature control.

And forget that vape shop! Those guys are gonna KILL ya. And they probably overcharge. Read here, buy online.

This was probably your current problem with the battery short

That being shown , the battery IS a good battery if it is in fact a Samsung 25r but is not rated for the type of build that you used it for so it is only bad in that situation if you where to build .4 or above that battery is what I would use , as other member said you really should learn with a .9 to1.0 build or above and be very consistent at it before attempting lower , never listen to the knuckleheads who work at vape shops , if they know what they are talking about it will be obvious that they do , I have 1 local shop out of 6 that has a knowledgeable employee base and they know Avery detail about every single product they sell off the top of their heads

Thank you Louis I knew you would be here I posted a pic in my last post showing the 510 problem with the atty

howdy - and welcome - you are in the right place, sister - and glad you are okay - sounds like the set up you were using had major potential for disaster written all over it...

being newer, you REALLY would be better off staying in the .5 ohm range for now - honestly, if you want to play with builds that low, get a regulated mod capable of both handling low builds AND keeping you safe... make sure you have good, authentic batteries rated for that kind of amp output... a .09 ohm build on a single 18650 battery attempting a nominal voltage draw of 3.7 volts is going to pull 40+ amps... NOT a good place to be... samsung 25r is a decent 20 amp CDR battery, but not going to do well at all in that kind of scenario

PLEASE - do some additional research on battery safety - I am going to tag @Mooch - his bench tests give you a great starting place to understand what you need to be looking at in terms of battery safety and his blog is excellent...

don't get me wrong, i am NOT dissing the mech mods, but I have heard a LOT of issues revolving around the SMPL and attempting builds that low when you are newer to vaping is a recipe for disaster - rule #1 - understand battery safety and BE SAFE (vaping is significantly less cool when you are perhaps missing your lips from an accident with an angry battery put under stresses it was NOT intended for)

again, glad you are here and vape safe, sister

Thank you for the good wishes and warm welcome and am now following mooch. And will read over his post later. I have tried to do research and I'm seeing now don't trust a salesmen and most online q&a have bogus answers. And most single article blogs, articles probably aren't a reliable source.
