Im to scared to use an RDA...should i be?

[Rezyuz]

My history:

Started off 4 years ago with my Ego and actually always sticked to the commercial line of ecigs. green smoke > 10 ego's > Eroll > Egrip > Evic supreme with Delta.

Why? Because in my country/city there isn't anyone who is an expert, a shop that will explain stuff and the only stuff available in stores are Joyetech and other major commercial companies. If you go to a local vape store here and mention you want to buy a clearomizer they will say "a what?" and you just have to point it out.

So heres the problem: I always have the feeling im not having a good vape experience as the juice leaks, the vape isn't good flavored, to little clouds. And i want to step up to the next level (i always saw an evic as a line between normal personal vapors and boxmods/mechs). So i wanted to buy a boxmod and i got one last week as a present. The Vaporshark rDNA40.

But i got NO clue what to do with it. I checked countless of youtube video's, hell im even an ex physics student. And still i cannot safely say whats wrong or with regarding building your own coils (resistance wise).

Everyone keeps speaking off batteries being able to blow up when you don't do it correct. And this makes me worry, if i went RDA mode on my vaporshark and made a coil and i test it on a resistance meter and it shows 0.8 ohms will it be 100000% safe?

So basically my questions, if you guys can be so awesome to answer them are:

1) If the maths are right, and my coil is tested at a resistance meter to be proven above 0.5 ohms (using Sony VTC5) will it be safe? always? So 0.6, 0.9, 1.2, 1.4 etc?

2) How long does a self build coil last? How do i know to change?

3) is there a battery that regardless of mistakes is so strong that it cannot explode under any circumstances vaping related?

4) Why single, dual, or triple/quad coil build?

5) And last, is building your own coils really that dangerous if you go below 1.0 ohm to lets say 0.5 ohm on a Sony VTC5 or LG 2500mah 35A 18650 battery? Lets say i completely mess up my coil and make it 0.1 ohm, what would happen if i fire it up?


Thanks in advance guys, i really want to step up with my vaping experience, but the you tubers just make it seem al to easy while i keep reading about huge risks everywhere else. Hopefully i can get some more insight here!

1 - With ohms law - 0.5ohm coil off a freshly charged 4.2v battery will draw 8.4 amps, any battery above a 10amp continuous draw will take care of that easily. Sony VTC 5 (Genuine!) will not even blink with those. Going above that, (0.8, 1.0, etc) just decreases the amp draw on the battery so it taxes the battery less.

2 - Depends on the gauge of wire, juice etc, however building your own coils allows you to dry burn them and clean them off. I have a Kayfun that's been going for around a month now on the same coil, I've rewicked it about 8 times due to juice changes but its still going strong.

3 - Not as far as I know. If you short a battery and it starts a catastrophic failure, any battery is a hazard. As long as you KNOW you have no shorts, and no crazy 0.000013 ohm builds, you'll be fine. I routinely check my RDAs on mechanical mods, and still occasionally glance at my box mods to make sure there's no short from the RDA getting bumped or a wrap coming loose.

4 - Up to you for vaping tastes really. They also play a role in battery life, My dual coil builds will drain a battery faster than single coil when I'm chain vaping. Never went more than dual though.

5 - 0.1ohms your're drawing 42 amps from that battery which isn't rated for it. I don't know the pulse rating for the VTC5, but long story short it'll start heating up and could end up in meltdown mode. Realistically in my experience it's hard to bugger up a coil that should be 0.5 to down it to 0.1; if you don't trap them tightly and they come loose it'll most likely just end up a short and you'll know that bloody quick with the heat.

Your best bet is to spend a few hours reading through the battery safety threads, studying ohms law and checking some of the very convenient coil calculators that tell you how many wraps per given diameter will give you whatever resistance. They're great. I have yet to have an issue where a coil screwed up, my only incident was a short because my RDA post came loose and negative connected to positive and proceeded to arc weld itself together but I noticed after a few seconds and managed to save the battery and mod from going kaboom.

Vaping is never 1000000% safe. Nothing with electricity, batteries, and current draw is, however if you pay attention to modding and coil building you reduce your chances for having a failure by a LARGE margin. If you're ever in doubt of a coil - throw it out. Kanthal is cheap as hell but your face can be expensive to rebuild.

Scaring Noobs is easy, but it is important to understand Resistance loads and battery performance to use equipment safely. It is actually Rare for a Battery to explode but it has happened and it is 99% of the time a defect that causes the issue.
Bad Coil shorts are rare. Idiots building to .03 on a $10 retail meter are asking for trouble.
People Building coils cleanly at .8ohm and using all proper procedures, i.e. checking each step will rarely if ever encounter a problem.

You might consider purchasing an Atlantis or Kanger SubTank as a next step.
Both are getting excellent reviews. The Kanger SubTank even has an optional Base section for learning RBA builds.
RDA(dripper) - there are a boat load of nice ones around. Unfortunately there are as many disappointing ones around.

I would recommend starting with one of the tanks.

 

[Verb]

1) safer than a clearo
2) in the beginning I was changing my coil every couple of days just to learn/ now a couple of weeks to a month (usually breaks when rewicking)
3) no, but you have a regulated device, which adds some protection
4) single to start. Anything more and the difficulty goes up due to the need to balance everything. But after a couple of weeks/months go for it and see if you like running duals
5) No. And impossible to screw up like that if you have a proper ohm/multimeter.

My 0.3 builds are why I use an Ohm meter, as well as my multimeter that was 10x the price of my $15 reader and if both read the same, I'm pretty sure I got the coil right.

 

[Rezyuz]

My plan was just to make it 0.8-1.4 ohm min/max anyways, i never intend to go extreme low builds. What i was scared about was what happened if i made a 0.8 ohm build and up my volt to 40 for example if that would be a problem.

And mainly, if i checked it on the ohm meter and it showed 0.8ohm on my vaporshark DNA battery where all say 0.5 even is already safe. that it in no way (unless defect by default) would cause problems. And according to you guys it doesn't, so im off to building my first coil this week after another few days of research XD

Could you explain how its safer then using my aspire atlantis? I can just put that on and max it to 40 volts without problems right?

Absolutely. I have friends who use the Atlantis on box mods with 30-40 watts all the time. The thing wicks like a CHAMP and can keep up with it. Bottom line for me though is I'm cheap and I like to tinker. I can build probably 100 coils for the price of one factory made atlantis coil. I'm using a 0.3ohm dual coil right now on my RDA with 40 watts and its lovely, not too hot at all just slightly warm which is great in a Canadian winter.

Thanks for the advice all, really appreciate it as when it comes down to RDA's youtube is to...easy going about it and articles are to harsh. Time to get my hands dirty (well, dirty in terms of labour, no explosions :<)

RDA's IMO are easy as heck to learn coil building on, because there's no tanks to drain to switch out a coil at all. Open it up, tear the coil out, done. What I did when learning was stay above 1 ohm for a while and started stepping down slowly to things like 0.8, 0.6, 0.5, 0.4 and I'm finding my current sweet spot is 0.3 on my drippers and 0.6 on my RTA's; it's all about personal preference and learning to build your own lets you vape exactly like YOU want, not how a factory tells you that you can.

1) No.
2) Weeks, or months depending on gauge (thickness); thick wire will last longer, but thick wire is lower ohms
3) Not yet; I'm plugged into the wall most of the time.
4) more cloud; I vape singles.
5) how dangerous driving a racecar is, depends on who is driving.

OH! forgot to share this if you haven't seen it already:
Steam Engine | free vaping calculators

Awesome resource for rebuilders, ohms law calculator, coild wrapping calculator and more. Gives me a quick reference for how many wraps I'm going to be using and anytime I check the resistance after, I'm VERY close to what these guys put out.

Your dna 40 might go up to 40 watts, not 40 volts.

 

[Rezyuz]

Haha yeah realized that about the 40 volts

Thanks for the link btw Neo, and regarding to your earlier comment, thats exactly the reason why i want to try RDA/RTA's because i want a perfect vaping experience for me. And my current stuff/commercial stuff in stores in my country can't give me that. The best vaping experience i have so far is my Evic supreme + delta triple coil but i can't stop thinking that theres way more beyond that.

I know what you mean. I started with kanger coils and hated them. Went to nautilus and the flavour slapped me in the face. Then I grabbed a dripper and tried rebuilding and had my "WOW" moment. Haven't looked back

You're not scared of using an rda, you are scared of subohming;

two completely different things.

Get the rda, and run a 32 gauge 2 ohm single coil and get some experience;
a week later, if you add a second 2 ohm coil, you'll be down to a 1 ohm dual coil;
and a week later, if you add 2 more 2 ohm coils, you'll be down to a 0.5 ohm quadcoil.

 

[towelie]

The DNA 40 has protection from the exploding scenario. It will read the batt you put in and not let you fire over the batts amp limits to my knowledge.

Yeah thats true, guess i formulated that one a bit wrong. i like your way "learning" how to build coils and go lower to the personal sweetspot. Thanks for the great advice.

I thought that was only in temp protection mode using nickel wire.

 

[POTENTCITY]

There's no reason to be scared now n days they selling already made coils , you don't even have to build now. I started vaping with a nemesis clone friend showed me easy 5 wrap coils and it was over from there. Just get some good battery's like Sony vtc5 which can handle .1-.2 builds no problems . Just always make sure your coils never touch anything easy
