Using a resistance chart to find volts?

[boyo1991]

Hey guys. If my mod isn't vw and only vv, I am assuming I can use this chart to make sure my battery doesn't explode... Correct?


BTW that attachment uploaded wrong.. Its not really that blurry.. Let me find the original link..

Those Safe vaping Power Charts were designed as a general guideline to help one choose the correct voltage range for a certain resistance (ohms) cartomizer.

I'm not sure if I follow your rationale in how the chart could help keep your battery from exploding. It could help you avoid frying an atomizer in the carto if you were applying too many volts/watts to the coil.

The nice thing about a variable voltage mod is it will have built-in protective circuitry which will cause the mod to not fire if there is too much power being applied to an atty and probably give an error code of "OP" (over powered).

That chart is kinda outdated given modern RBAs and devices and coiling techniques but I am sure it will continue to haunt the internet for years to come as people who dont have a true working idea of how vaping actually works will continue to bring it up and reference it.


There are many facets to battery safety.
The biggest one for us pops up for Mech users, in particular sub ohming.

The general key is to not over stress your battery. Any given battery has an amp limit of what is safe and the further you stay under that limit then the safer you are (assuming all other factors are being dealt with safely)

using ohmslawcalculator.com you can input your voltage

(4.2 would be a liberal max for mechs assuming you are not stacking batteries or built some custom mod that uses a completely different battery that is commonly used)

then put in the resistance of your coil and hit the calculate button which will tell you your required amperage. If said amperage is lower than your battery amp rating (preferably much lower) then you are gtg.

As previously mentioned if you are using a regulated VV-VW device then you generally do not need to worry about this as much as the device itself has a built in amp limit which it will not (or should not) let you exceed.

Despite that, the trend for regulated mods is to use IMR type batteries as an extra precaution on top of the fact that many vapers have both mechs and regulated devices and having a battery that is appropriate for either is always a good thing.

Now if your battery question was not related to that please clarify and we will bring you up to speed.

The reason I ask this is because I want to start getting into making coils.. As new models come out and the old ones no longer are shipped (like I clear 30b is the one I have now that I'd like to be able to rebuild if need be) and I don't want to have to worry about making the resistance be a particular amount each time. I want to make the could what I'd like and not have it explode in my face lol.

You're over thinking it.

Buy good batteries (Sony VTC4 or 5 for 18650 or Efest Purples for any size) and you should be fine as long as you aren't building super low Ω coils.

Use this calculator to make sure you aren't over drawing and there will be no problems.

Thanks lol I just hear about people saying building coils is hard blah blah blah but from what I've seen its actually really easy o.o

So thanks!

If you have a Ω-meter and you stay out of dangerous territory, it's not very hard at all.

Again, just make sure you have good batteries with high amp ratings.

For 18350, I exclusively use Efest Purple which have a 10.5A rating. For 18500 I use Efest Purple with a 15A rating. With 18650 I use Sony VTC5 with a 30A rating and Efest Purple with a 35A rating.

Stay above .4Ω and you should be good with any of those batteries.
