Afraid of blowing my face off

[handn]

Help me out here guys. I am a beginner and I plan on sticking to sub-ohm vaping. I bought a build off my friend the other day and I wrapped a new coil that works really well. It's a Tesla mech with a Nimbus atomizer on it and the new single coil I wrapped. The thing is, the battery has no info on it, so I can't really do all that Ohms lay stuff. My coil runs anywhere from .6 to 1.0 Ohms and I'm not sure if it is too low of a resistance for my build. Is it dangerous or not? Thanks so much, I'd like to avoid explosions near my face .

Um...it does in fact have info on it lol, it is a "sony" vtc4 as per the top line of writing "us18650vtc4 c4" and then the second line is the batch number for the battery...assuming that this is an "authentic" vtc4 and that your ohm reader is in fact still operating within it's +/- .04% accuracy that it should then you have absolutely nothing to worry about with that set up

If you look closely on the wrapper (1st pic), the faint black characters say "VTC4" near the end of the first line.

If it's a real VTC4, that bad boy is 30A continuous, good down to 0.14 ohms, which you are well above.

However, you can't really say whether it's authentic, or how hard he used the battery - did it ever get over discharged, has it gone through 1000 charge cycles, etc.

I'm no e-doctor, but I'd say a 0.6 ohm build should be fine, as it draws less than 10 amps.

But I'd also get yourself some fresh batteries from a reputable source, for peace of mind

Good score!

The battery appears to be a Sony VTC, so you should be looking at a 30amp continuous drain. You will be good all the way down to 0.2 ohms.

Some will disagree with me but you can run those batteries quite low without any problems... a "conservative" build of .5 ohms would even be fine but, again, this depends on if it is authentic and the accuracy of your ohm reader....best way to check both of those things is to do a google search on "how to tell an authentic vtc4" and comparing your ohm reader with a friends to see if they get the same reading (very unlikely that both will be off by same amount and if they read the same I would say it is safe to say they are accurate)

From your first picture it appears there may be some info on the battery. There looks to be some faint printing on the side, under the plastic wrap. If you could get a picture showing it a bit clearer, along with pictures of the top and bottom of the battery.

The color makes your battery appear to be a Sony VTR which would be a very good thing. If you run your coils between 0.6Ω and 1.0Ω you would be well within specifications for a Sony.

Here's a couple links that will help a lot if you intend to keep using mech mods and do it safely....

And yet, I remain concerned, simply because when wrapping your own coils, you SHOULD know enough about ohms and batteries to play safely.

Key points -

1) IF it's a VTC-4, that's a great battery. But it's a good enough battery that fakes abound. Looks real, you're probably OK - but don't get batteries of questionable lineage - buy them new from a reputable vendor.

2) "the battery has no info on it, so I can't really do all that Ohms lay stuff"
Not sure what that means. Regardless of what the battery is, your maximum draw will be when it's charged. When it's charged, it's 4.2 volts, or you are already in trouble. Run that and your resistance through an ohm's law calculator, and you'll see what you're planning to vape.

3) "My coil runs anywhere from .6 to 1.0 Ohms and I'm not sure if it is too low of a resistance for my build"
I think there's a terminology thing going on here: your coil IS your "build".
But more importantly - do you mean the ONE coil you built is changing from between .6 to 1.0 ohms? It should not do that - it should be stable. If it's flickering around, something's loose... Just checking. If you mean you've built several, and they fall in that range, that's fine....

I am a beginner and I plan on sticking to sub-ohm vaping.

I think that's one of the scarier phrases I've heard today...

Do I want to know what you're using to charge the battery on?

 

[cloudguy00567]

At least you've got an ohm reader I use sony vtc4 batteries and go down to about .18 and have had no problems whatsoever

 

[WattWick]

I wouldn't use a battery that I myself didn't order from a reputable vendor. Lots of fakes out there.

That battery is more than enough i run my purple efest 18650 with coils around .34 and i still have alot of buffer if i wanted to go lower on the ohms
