The VTC4 is one of the safest batteries available. It's a GREAT battery. But nothing is totally safe - we're still talking about a lot of power packed into a small space. Here's a couple links to some of the accidents people have had with this type of battery (again, these are the safest ones we have right now). Please note, your VTC4 is an IMR (or "safer chemistry") battery, just like the ones in the links below.

I've bolded the important part here. In this case, the poster doesn't know the amp rating of his battery, doesn't check his coils (he doesn't even know how many ohms he's using), and has no idea how low his batteries are when he recharges them.

A mech mod is almost exactly like playing with a gun - if you know what you're doing and follow standard safety practices, you can use it for its intended purposes with a reasonable expectation of safety, but if you've never picked up a gun before, know nothing about them, and someone just hands you a loaded gun with the safety off and says "all you have to do is point it at something and pull this little trigger thing" with no other instruction (like the situation the poster is in), you can easily hurt or kill yourself or someone else.

So he should put it away for a month or two because he's what 2 years old? Your comments are freaking ridiculous. How about you point him to the info he needs instead of scaring him and making it sound like a mech mod is a loaded gun. The learning curve is like less than a day, not 1 to 2 months lol.

Good info , I do apriciate the safety warnings . But I highly BELIVE wit a simple dual coil setup and a vtc4 or 5 battery I won't have any problems , my boy been doing this for over a year with no problem . Of course you need to make sure your coil never touches the post or deck when firing. I'm still vaping as we speak

You would be fine with aw or efest batteries. Mech mods are so simple and as long as you follow the basic rules you'll never have any safety issues. People are just way too doom and gloom around here when it comes to mech mods.

To someone who has a basic grasp of the relationship between voltage, resistance, power, and current, or to someone who can do basic math and picks up concepts like this quickly, yeah, I completely agree with you.

To someone who says things like "i dont really understand all that ohms situation lol", never bothered to test a coil, and would rather ask us about batteries because he doesn't know the difference between the three types and doesn't want to look it up? Yeah, it's going to take that kind of person a month or two, if they ever learn at all.

This guy's just begging for a Darwin award. "I apriciate the safety warnings, but I BELIVE" this is safe (although I've haven't bothered to look anything up or learn anything... I just think it's safe because I *feel* that way and want to keep using it without doing my research)? Really? You think this guy should be running a mech and a dripper (with dual coil setups he builds, but doesn't know what resistance they are) without even using a fuse in it?

You must have a LOT more faith in humanity than I do. I know too many stupid people.

Novamatt no reason to get disrespectful you don't know me and I'm sure if you did you wouldn't talk no stupid people garbage to me , you got some good info but you starting to sound like a scared nerd . We live once live your life , with a vtc4 if you building simple 4-5-6 wrap coils tight n make sure they don't touch post you will be fine no reason to test because the battery can handle it . Relax smart guy

I always carry two batteries I don't chain Vape or cloud chase , when I feel the Vape get light I switch batteries it isn't rocket science . I'm sure for those build quad coils or something in that range it would be smart to test your coils but for a simple 2 coil build there's no need to hit the textbooks lol

You're proving my point for me here.

I give up. Can't help someone who refuses to learn. Figure it out yourself and try not to get hurt. Good luck.

I think this is frustrating to a lot of people b/c there are inherent dangers to unregulated devices. Mechs are awesome devices but you should take precautions if at all possible. Sony VTC4/5 batteries are a+, MNKE's will certainly work, and AW IMRs in 18650 will also allow you to fire down to fairly low resistance. But, if at all possible, please invest in an ohm-reader or multimeter. It's not just about checking resistance in your builds but also checking for shorts. Yes, you have to make sure you coil doesn't touch the deck but there are other things at play that could mess up a build. Good luck and be safe.

I think your the one disrespectful. The more experienced guys here are trying to help you out and trying to inform you that you should have full knowledge of what your doing when you deal with mechs and rebuildables. You should have a working understanding of ohms law and Amps at the very least. VTC4's are safe chemistry batteries. It doesn't mean they are safe. When they vent its like a furnace and if your mod does not have proper venting it will explode lilke a pipe bomb. Do you know how many Amps your coil is pulling? No, because you don't know your resistance. Did you know that if you decide to use 18350's that the Amp limit is much lower and that the same coil that might be fine on a 18650 won't be on a 18350? Do you know that different batteries have different amp limits? Without the proper knowledge you are just begging for something to go wrong.

Instead on dismissing, ignoring and being flippant about what the people who know are trying to tell you, you should be thanking them and taking their advice. Do some research. There is a ton of information with a quick google and on this forum.

Mech's and rebuildables can be quite safe if you have the knowledge. You start a thread asking for help and you just ignore it. :facepalm:

No you should always check your resistance before using it. 1 coil, 2, 4... It doesn't matter. You don't need to be a genius to run a mech mod but you have to learn to be safe and stay within the limits of the battery.

POTENTCITY,

Just a few quick questions about your 4-5-6 wrap dual coil.

Are you using Kanthal A-1, Kanthal A, Kanthal D, NiCr or Inox316L wire?
What gauge wire is it?
What is the inside diameter of your coil?
Are the coils spaced apart or squeezed together?
How long are the coil legs?
Is it a 4, 5 or 6 wrap coil? It makes a difference.

Just cause I am bored....

All the following coils are 2mm inside diameter and the numbers are a calculated guess on my part...

two 4 wrap coils of 34 gauge A-1 will result in a dual coil about 1.5 ohms
two 5 wrap coils of 34 gauge A-1 will result in a dual coil about 1.8 ohms
two 6 wrap coils of 34 gauge A-1 will result in a dual coil about 2.0 ohms

two 4 wrap coils of 28 gauge A-1 will result in a dual coil about .35 ohms
two 5 wrap coils of 28 gauge A-1 will result in a dual coil about .42 ohms
two 6 wrap coils of 28 gauge A-1 will result in a dual coil about .48 ohms

The above are all within the working limits of the vtc4 battery but will give a different vape. Just because the battery can handle it doesn't mean it will be a good vape. I am sure one of those configs will give you a nice vape but some will be good, some fair and some just spraying juice into your mouth. Also wouldn't it be nice to know what you're getting so you can work with it and tweak it when required. I've built hundreds of coils and for some reason I never felt it was a big deal to double check my guess with an actual multimeter, only takes a few seconds to check ohms and for shorts.

Battery safety is obviously always an issue with any lithium battery, they don't even have to be under load to do the big nasty. Myself and others just want you to be informed that there is really nothing called a safe lithium battery, maybe safer but definitely not safe. Better to know your numbers instead of shooting in the dark, it really is quite easy when you get the hang of it. It may seem that there is nothing more to building coils than wrapping a piece of wire around a piece of wick but you really should try to open your mind and learn a little. Your vaping time will improve greatly from a little bit of knowledge.

BTW: what the hell was this thread about again? I think I am wandering. lol

I do 5 wraps around small screw driver that we use for screws on the deck. I use a1 28 gauge ken wire , i squeeze the wires tight together , many are stressing the fact I don't test my coils but I go to few Vape shops and deal with a few vapors and they all seem to tell me I'm fine how I'm doing it with the vtc4 , I understand the safety concerns and once I get my vtr I will start testing them I guess

I took this comment the wrong way , my apologies - in all reality this thread makes me want to go the extra mile and do my homework on what needs to be learned . I def appricate the advice from everyone and def want to be safe vaping out my mechanical mod .

Glad to hear that.

The energy stored in these lithium batteries amounts to the energy of a bullet.
So there's serious enough potential danger to warrant a healthy respect for them.

If you look at the 510 thread on the mod where the tank screws in and think about it, the very middle part is connected to the positive terminal of the battery, and all around it in a circle barely a fraction of a millimeter away, is connected to the negative side of the battery. THAT's how close you are to a short - barely a fraction of a millimeter.

I agree with those here that suggest that you should put down the Nemesis and RDA until you read up on battery safety, get an ohm meter or a multimeter to check your coils, and understand ohms law. It's quite easy to get a short in the RBA/RDA without it showing, and whatever battery you use a short can give very nasty results. By the way, not all green Sony batteries are of the safer chemistry, high discharge VTC series. You're quite literally playing with fire (and to the person who's dismissing the safety concerns by the rest of us: perhaps you too should read up a bit before you dismiss our concerns).

A metal chip, paper clip or key can easily make life interesting. :p That's why I make it a habit to put a m5 nylon bolt in after removing atomizers. Keeps the area cleaner and makes me feel better when I am forced to pack mods away with the batteries in them. Sometimes while traveling I can't bring batteries onto a plane unless they are inside of a mod. If anybody uses this tip remember to not put the bolt very tight, it doesn't take much to hold it in place securely and taking it out after is easy. I also lock the switch on my mods but the little bolt makes me feel better. At home I don't store mods with batteries in them.
