sub-ohm and wattage

[nath100nek]

ok so i kinda feel stupid for posting this but kinda still ignorant with sub-ohm.
i have used the ohm calculator to see how much wattage i will get at a fresh charged imr18650 battery 30A at 4.2 volts with a mod. say im using a .14 ohm coil, then i get 30A and 126 wattage which is the maximum discharge rate for the battery... but ive been looking at the safe vaping chart and the safe wattage for 2.2ohm is 8.21watts which is pretty low comparing to 126 (Im guessing 8 watts is the safe area) if i go over 8 watts does the coil actually start burning? plus i have seen people vaping at lower than 0.1 ohms which will go over the current of the battery can draw and produce more wattage. are they just risking it? im surprised their battery hasnt blown up on them haha. i dont want that happenening to me..

sounds dangerous, I would try the more experienced forums, rather than the new members

 

[nath100nek]

ok.. how do i move this over to the veterans forum?

You'll need more posts before you can post in the specialty forums. Rebuildable Sub-Forums

In the meantime, PLEASE vape safely. You are admittedly new to this rebuildable business and really have no business to be doing sub-ohms without some more research and experience under your belt. Build safer resistance coils (1.0 ohm and higher) until you have perfected those before jumping into the deep end of the pool before you've learned to swim.

FYI, those Safe Vaping Power Charts were designed for factory-built coils, specifically for cartomizers. They do not apply to sub-ohm rebuildables. Rebuildables are an entirely different ball game.

It sounds to me like you are not all that experienced with vaping yet nath100nek. In my opinion it would be a very good idea if you did a bunch of research into vaping before you venture into the 0.5 ohm build realm and lower. 8 watts on a clearo or 12 watts on a carto can keep you off cigarettes until you know how to stay safe at the higher power levels. Having this experience will also give you invaluable knowledge about vaping that will serve you well when you go with more power.

Baditude already gave you a bunch of links to great resources on this stuff. Please read it and learn from it.

Anyone going below 0.2 ohms is pushing limits, no matter what battery they are using. Yes, they are risking it. Their batteries will probably not blow up if something goes wrong, but they will vent and that can be quite dangerous.

Vape safe my friend

With all the wise words that were said.. Since you are new.. I think you'd be much better off and SAFER sticking to building coils around 1.5-1.8 ohms. There is a lot to really understand before you get into sub ohm vaping and and .1 is crazy. I've been vaping for a while and have done massive research and I dont go under .5 ohms and I'm using top of the line 30 amp batts. Listen to the advice here for your safety. Start with a single coil 1.5+ ohm and research and learn. Be safe my friend.

im not exaclty trying to build one yet but i was just curious of how it worked been doing research but couldnt seem to find the answer...
still havent got the answer tho. is the wattage that high OK in mods?

you may not be able to post in the specialty sections but you can read through them. Use the search function to help find relative posts.

Your battery is the weak link and what you need to worry about. It's also what everyone else is worrying about for you
People will be reluctant to help you on this topic and may even sound a little harsh... It's only because they care

Keep doing research, everything you seek is here and then some. There are quit a few sub ohm users that post builds and set ups.
Baditude posted some awesome reading material for you as well, although I don't think he goes sub ohm... But he's a battery safety guy that's for sure

 

[nath100nek]

Thanks jbl.. I guess ill just have to do more research even tho i have already read all the links that baditude has linked in the past. Yet nobody can answer my simple question..

The question is not as simple as you seem to think and that is why you are getting the answers you are getting.

Is my car safe to drive at 200mph? That's not a simple question, but much like the question you are asking. There are many factors involved and folks are trying to help you by letting you know you need to know more so you can ask questions with the factors included that are important that help determine the answer.

I'll directly answer the question. The vaping charts you are looking at are usually giving power or wattage for clearomizer and cartomizer vaping. These toppers are very restricted in both airflow and wicking and that is why it is recommended to use them at the settings given on those charts. If you try to go higher, you will probably end up with a dry hit due to insufficient juice reaching the coil or a harsh burnt tasting vape.

When you build your own setup on a RDA (rebuildable dripping atomizer) or RBA / RTA (rebuildable atomizer / rebuildable tank atomizer) you can tailor the wicking performance and airflow to your needs. Most RDAs and similar toppers allow you to greatly increase the airflow and the wicking capabilities to allow you to vape at much higher wattage.

You can also use other coil building techniques to improve both vapor and flavor without having to drop your resistance to the levels you describe. I can build a 1.2 ohm coil that will rival the flavor and vapor of a .5 dual coil build. It puts a lot less strain on my batteries and allows them to last longer too.

As everyone else has said, just keep reading, watching videos and keep learning. When you feel you have the correct batteries and the right knowledge, start off with a simple RDA and build yourself a coil that meters out between 1.2 - 1.8ohms and experiment from there.

There is nothing magical about going below 1 ohm, but as you keep going lower with the resistance, the stress you put on your battery increases.
We've seen posts of people that have experienced accidents with venting batteries - hence the 'safety first' posts you see above.

 

[nath100nek]

thanks guys now i actually understand now i just had to learn more about the ohm's laws. i wont be building a .1 ANY time soon....

 

[zanedog]

lol, yeah stay away from that kinda coil.

It is a very simple question.

The answers are;

If you know what you are doing, it is safe.

If you do not know what you are doing it is not safe.

So, do you know what you're doing?

i got it now don't worry. was just curious how, and why people go so low with ohms. i wasnt going to build one to start with but now i know that it is NOT safe, i prob wont be building one

 

[zanedog]

They are safe as safe can be if you do your research.

I like 25 watts, 60 plus would choke me.
