should I be worried?

I simply cannot condone your usage patterns based on your knowledge of ohms law.

My coworker is currently running a quad parallel coil which is actually 8 coils. I know for a fact it is below 0.1 ohm.

A good rule of thumb for utmost safety on a given cell is to not draw more than 2/3 of the rated amps at a given time. You could theoreticsally pull 29 amps of te 30A battery and not have issues. Does that mean its safe? Hellno! Frankly i think my coworker is a total .........

Youre going to be fine.

At best a fresh batttery will output about 3.9 volts under load.

3.9 x 3.9 = 15.21

15.21 / .25 = 60 watts...

60watts / 3.9 volts = 15amps

Id say your safe, but really i hve to disclaim this by sayingnthat more research on your part is required if you want to continue vaping this style. IMO....

Well I dont understand why people are getting mad at me I have stated that I have not fired it I went to check here first. I have not even done anything wrong. Im still learning


Ignore it man, you're doing fine. You got yourself quality batteries. You checked your amp draw. The voltage figure you had was incorrect, but that's been resolved now, and since you were using a higher voltage figure you were actually giving yourself more safe headroom anyway. Reading a number wrong is a mistake anyone can make, it doesn't mean someone can't build properly.

Your Sonys are rated for 30 amps continuous draw which means holding the button down, and not releasing it until the battery is discharged to it's lower safe voltage. They are rated even higher for pulsed draw, which is what we do when firing our pv for 5 seconds or whatever. As a precaution it's seen as good form to stay within the continuous rating even though the load we place on the batteries isn't.

A .25 ohm build with a fresh battery is going to pull just under 17 amps, which is well within the continuous 30a rating. Assuming your batteries are authentic, your build is very safe to use with your batteries.

As for the safety of the build itself, you need to make sure you build is top-notch when hitting such high power levels. If you are running a dual coil that means each coil is a .5 ohm coil. Not really that unusual or extreme for a single coil, but definitely on the lower end of what most people do. I'd personally suggest sticking with 26g wire and make sure to have a good sized diameter so you have a lot of juice available.

Make sure to pay close attention to your wicking, immediately after a hit check your coil and see how dry it is. Coils at that high of power levels boil off juice REALLY quick, so if your wick isn't keeping up you're going to run into dry/burnt hits.

As long as your wicks don't dry out, and your current draw is within what the cell is rated for, you really don't have anything to worry about and can experiment to your heart's content ;)

Here's a nice calculator for people like us to use>>Steam Engine | free vaping calculators ...the only thing it doesn't do is check your rba/rda etc for short's ;) .. it's a good idea to check for short's after popping the cap on unless you've been running the coil/s for a while without any issue's, it's so easy to snag your coil with the top cap and produce a short!! :)


I adv coil/s around .2-.5Ω..... I started out on a vw device with a 1.2Ω coil and was very happy, i also wondered why people were vaping at such high wattage and couldn't see the advantage until I got my mech, which to get anything close to what I was vaping before I would have to make a .8-.9Ω coil.
The problem I was getting was that from time to time I would get something similar to vapour's tongue, i'd still get the throat hit but the flavour for me sometime's wasn't there, i got this very same problem when i was on the 1.2 coil's or even worse on the ce4's.
It finally dawned on me that what was causing this was constant vaping, when i started vaping between .2-.5Ω i noticed i was vaping less, pulling less, pressing the mod button less & getting more flavour. :D

byebye vapour's tongue!!
hello flavour!!

i normally use cotton and have even used it inside nano's (@.2-.5ohm)np without burning the wick.

you can lose the true flavour on some tobacco's at high wattage but i've found if that's the case then using ekowool is a good move.
