hi guys.. so I have a caterpillar rda on a 18650 mechanical mod(dunno the name , was never told) and I just recently started building my coils. my first single coil without a ohm meter(pretty stupid , I know) caught on fire.. so I stopped until I got the right wire & equiptment. now that I have 28g a-1 kanthal.. what'd be a safe ohm build to have daily? i vape at 0.54 ohms on a dual coil & the battery never gets hot. but I don't want it to blow up in my hand so.. any suggestions? I use a Sony vtc5 btw.
What's a safe ohm for dual coils?

Without a way to check your ohms on your coil build, you don't know what you have, so ohm's law and battery safety are out the window.........spend the $5 on an ohm meter! The SONYvtc5 is a 30 amp drain, so down to 0.2 ohms your good, 0.1 not so much! Good luck and stay safe!
a freshly charged 18650 is no higher than 4.2 volts. and at 0.54 your pulling 7.78 amps your in the clear. bookmark an ohms law calculator and dont go above 20amps on that battery. type in the 2 fields you know, such as the volts and ohms, then press enter and it will give you the amps.
hope this helps, and good luck on your adventure!

Are you sure your Sony VTC5 batteries are real? From my understanding most of the ones being sold now are fakes. When and where did you buy your batteries?
You need some kind of ohm meter to have any clue to the resistance of your build. If you dont, you could push your batteries beyond their limits and have serious issues.
The limits of how low you can build depends on your battery and whether or not they are authentic.

So, Rollin,
Does the right wire and equipment include an ohm meter or a digital multimeter? I don't want to assume anything, but you said you are vaping at .54 ohms/dual coil...
You can use this calculator Battery drain | Steam Engine | free vaping calculators to calculate your battery drain. If you need an explanation on how to use the Steam Engine, here are some blog posts...

I picked up a ohm meter.. I've been building coils ever since I got it so im not just guesstimating the ohms lol and my vtc5 is authentic.. I got it from vaportek about 5 months ago & haven't used it hard.. never been totally dead & never over charged. thanks for the replies tho guys!
get a meter and keep it around .25 minimum..... if you hate your batteries then keep it above .15... if you want to see spectacular stuff .15 ( I usually wait for new years or the 4th of july to see spectacular stuff)
bad feeling? I'm not building 0.03 builds & taking 12 second hits.. just making sure what I'm doing is okay.
As long as you have an ohm meter and correct batteries (which you have) then you should be fine. As stated by another above - referring to an ohms law calculator is almost always a must, at least until you are experienced with rebuilding and can tell how many amps a certain build will pull.
I don't mean to be negative when I say this but what is it with a lot of new vapers jumping straight into sub ohming? To me it seems like trying to run before you can walk. There isn't anything wrong with a 1 ohm single micro coil.

I honestly just always end up building lower ohm builds & prefer the vapor production.. I don't mind anything 1ohm & above.. just a preference for me I guess.

4.2 Volts / 0.07 Ohms = 60 Amps or 252 Watts
3.7 Volts / 0.07 Ohms = 53 Amps or 196 Watts
That's 1/6 the power of my electric room heater on high, 1/3 of it on low. Lot of power to vaporize liquid.
EDIT: I'm just curious, have you ever checked the voltage under that load? Wonder what the battery is supplying with that much current drawn from it.

We do not talk about unsafe practices here on ECF.
Why build a coil so low that it's unpleasant to vape and most likely tastes like dirt (or worse).
Batteries in the vape industry are often mislabeled and not what you think they are. That can be very dangerous. People who don't know Ohm's Law, don't have a GOOD multi-meter, and don't know positively what their batteries are capable of, are a danger to themselves and to others around them. They become "headlines."
I'm glad to see we have members here that are helping and pointing out the dangers!
