VTR, batteries and rda's

[Maddrocx]

OK, I've been vaping for a few months now, started with a vamo v2 (gift from a friend) went from an Evod tank to a PT2, then started rebuilding my coils for my PT2 heads.

About a month or so ago, I bought a VTR v2 and an Igo-w. I've drilled the air holes on the cap (re drilling soon to be bigger) and I just don't seem to get the same amount of vapor off my VTR that I've seen on other regulated mod videos.

I've been vaping in voltage mode using Ohms law to reach 25-36 Watts (based on coil resistance), now the question I have will my new 35A efest batteries improve performance on my VTR? Or is it just not capable of that kind of performance?

I've even sub-ohm'd with the Igo-w (always single coil... Doesn't seem to like dual coil set up).. Lowest I've built thus far was a 0.6 nano, 0.6 parallel, 0.5 micro... None of which gave stellar results.

The batteries I have is one Sony 18650b (6A I believe) and a blue no name I can't find info on.

Now, I have a Stillaire v2 clone and a Cloupor DNA30 clone, and an aerotank base, on the way to me as we speak. So, is the VTR limited or will my new batteries improve my vape?

The vtr I beleive has a 3-5 amp limit on the chip it wont vape.past 15watts or 6volts and thats as long as it doesn't go over the amp limit. That dna 30clone would do the trick for you though. Dont quote me on the vtr spec I gave thats what I think I remember seeing -.-

OK, so if there's an amp limit... Say I'm using a 1.1 ohm coil at 5.5v I'll be Vaping at 27.5 watts... Correct? Or does the VTR stay at 15 watts regardless if in voltage mode?

You won't be able to exceed the amp limits of the VTR, whatever they may be. I'm rather surprised that you were able to fire a coil less than 0.8 ohms on the VTR.

Really, if you feel the need to vape sub-ohm coils, you should either get a mechanical mod or DNA 20 / 30 amp regulated mod with a 30 amp battery.

...my new 35A efest batteries...

Please be aware that there is some evidence that the purple Efest 2500 mah battery advertised as a 35 amp is actually a rebranded LG18650HE2 2500 mah battery which LG says is only a 20 amp continuous discharge rate battery. Efest 30 & 35 amp batteries

Unfortunately as stated above a regulated mod wont go past its maximum wattage or voltage. you need a mech to achieve the watts you are trying to vape at. If you end up getting one make sure your batteries are up to the job.
Vaping at 35 watts you will be drawing 8.33 amps from your battery so the 6A ones you have wont be nearly enough.
Make sure you use ohms law to work out the amp drain on your batteries which is way more important than knowing how many watts your vaping at.
A duel coil set up will effectively half the resistance of the single coil, so 2x1.0 Ohm coils will work out at 0.5 Ohms and 2x 0.5 ohm will work out at 0.25 ohm(70watts i.e. 16.8 amps)
A vv/vw mod will be unable to even measure the resistance below .7or.8 and will show a short on the display so a resistance meter will be needed to measure the coils.

He is absolutely correct here.

When doing sub-ohm coils especially, you have to know the amp limit of the battery. List of Battery Amp Limits

Use the Ohm's Law Calculator to determine if the coil resistance of your RBA will pull more amps than the battery has to provide. Going over the amp limit of the battery can have catastrophic results. Ohm's Law for Dummies

1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw

0.0 ohms = dead short

The batteries I ordered are coming from eciggity.com, hopefully they're legit.. Thank you for all the info, safety is what I'm after in the end, I think I'll use my tanks on my VTR and drippers on my dna when it gets here
