ignore me. I was talking about he IPV D2 that has no step down...my bad sorry!th
Thank you for your thatim thinking of how I can make my batt last longer.. reason why im thinking of making my coils low so it would fire in an instant with low wattage settings. am i thinking it right? sorry im new to vaping and these kind of devices.. by the way im using mutation x v4 atty with .50g kanthal how many wraps should I do with this to achieve like around .2 ohms or around that? first time to build my own ;-)
I had same issues you have in tc mode but since updating mine it's stayed rock soild with no resistance drift and has vaped perfectly with Ti wire. There is definately a touch of underpowering in Ti mode but it's stable(for now!)
What F & W your on For TI after the update ?
Am facing inaccurate Temp
Before upgrade was working fine
i do
since the updqte,its ok now
seems to have the issue fixed

Ironically, I never had an issue with 1.10 and was introduced to the "TC resistance drift" problem when I upgraded to 1.20 - .14 Ohm coil that kept drifting to .12 on the VTC and thus giving a poor vape.
Went back to 1.10 and issue was gone. Went back up to 1.20 and again, no problems, rock solid at .14 for > 24 hrs now.
The only difference: While updating the first time I had an atty screwed on. When going back to 1.10 and re-updating to 1.20 I screwed the atty off and pushed the Fire button a couple of times (to let the VTC know that it had no head) before doing the upgrade.
Don't know if that really made the difference or if I was just lucky and some voodoo causes the VTC to behave badly.
But I thought it was a good idea to share this experience - maybe it helps someone down the road....
For what it's worth, with a well regulated mod it just doesn't matter whether you use a higher resistance or lower resistance with regard to battery drain. For a given wattage the mod trades off amperage and voltage to maintain your selected power. The drain on the battery essentially equals out.
Play with http://www.steam-engine.org/batt.asp a bit and you will see that your run time comes out the same regardless of the coil's resistance.
The only thing that you have to watch for is to be sure that you are not drawing too much current (Amps) from your battery. Allow a good amount of headroom to compensate for a weak battery or other factors that can increase the current drawn.
Oh, and at that http://www.steam-engine.org/batt.asp page, click on the "How it works" link on the bottom left, and read up. Good info for ya there.
Hmmm, not quite. The reason SE shows similar run times is that, as you said, the res is not part of our amp calculations at the battery in our regulated mods. That's for mechs.
But we don't run dissimilar res coils at the same wattage, do we?
What the amps (at the battery) represent is the rate you are discharging the stored potential in the battery.
That is dependent on the watts requested by the chip, which in general, varies predictably with the res in the atty. Yes, a low ohm, high watts vaper will bring a battery to it's knees faster. Not because the res is lower (per se) but because the vaper can throw more watts at it. Higher draw, faster discharge.
I do. (But, yes, I know some do not.)
I bolded part of your reply because you bolded part of mine.
I always figured it takes more juice to heat up more metal. Of course more metal, used well, can result in more vapor.
That's the gist of sub-ohming. More coil surface, more power, more heat, more vaporized juice, more flavor.
Cloud chasing is just an affectation.
And I'm not convinced the pinnacle of flavor lives only at the bleeding edge of low ohms.
I do. (But, yes, I know some do not.)
I bolded part of your reply because you bolded part of mine.
No, I understand.
Your logic is fine until you try to factor in "... a given wattage".
The question was... can battery life be extended. The answer is ... yes.
What must be traded though?
I don't chase clouds, but do enjoy a nice exhale of vapor. And I can't seem to MTL anymore.
So there's only so high I can go with my res.
I agree because we can now pump volts into a coil that's far above what a 18650 can provide by itself.
I've never had a mech and was surprised how puny by pass mode is at 0.5 ohm. I just never bothered to run the numbers because it wasn't important to me. Now with temp modes resistance seems less important than ever.
For battery life, fingers, and faces.
Just updated to the V1.20 firmware. It does go to up to 75 watts now.
Will test the Temp Control all day today to see if any issues arise.
I haven't updated my firmware yet (I'm afraid I won't be able to return to the original firmware if I don't like the update)...but...in your photo the 4th line "Current 00.0A" appears to replace the "Battery" symbol showing the remaining charge.
Does the "Battery" symbol actually disappear with the firmware update???
It's just an option, the battery bar is still there if you prefer.

You should have no problem backing down by simply selecting an earlier file when you run the updater.
1.10 adds the "Live resistance" readout in TC mode, like the IPV D2, and the Ammeter to the displays for the bottom position... Battery, Ammeter, Puff Count, Total Time.
1.20 increased maximum wattage to 75, for both watts and TC modes.
Both may include undeclared stability fixes.
