    Hello!

    It could happen that it will be possible to implement VV mode for profiles. To start, it will be quite simple, without preheat and curves features, just plain output voltage adjustment, some kind of switching dominant unit for VW profile: either power or voltage.

    Do we really need it?

    What would be the benefits of VV ? In my opinion, it is not the best solution. Why should i use the voltage instead of Wattage? I use 1W increments, if i use Voltage Mode i would increase some Volts to get more Watts :D

    Ten years ago we used to use variable volts with the devices that where at the market. We all upgraded our devices and the vaping experience through the years. I dont thing that we realy need this option. My opinion.

    I vote No, why waste what little space is left on a feature that does nothing to improve/change the vape experience or the way the mod performs or functions?

    Necessary. VV gives the heating dynamics the most close to the dynamics of mechanical modes, including the "natural prehit" for steel and nichrome. This gives completely different sensations when vaping.
    VW constantly adjusts the voltage when the resistance of the spiral changes, which is not always a good thing.

    Well, I'll quote from one of the forums:

    I here foolishly put 20mm henesis, which is wound with a stainless steel coil, on the board. In the mode of varivata. I feel "something wrong" in the puff, the fur is much better. And then noticed that the board "swings" volts during the tightening, adjusting to the resistance of the coil changing during the heating process. As a result, the dynamics of the warming up of the coil turns out to be different than on the fur. Gone is what I call a "natural prehite of a stainless steel". It is necessary to fix the volts, but on this board either there is no varivolt mode, or I did not find it.
    I took off the atom, and the board threw the packs on the shelf in the far corner. On a fur the stainless works better, than on this board in the mode of varivata.

    Have a few words to add :)
    Probably, a lot of us started with early battery mods with bare VV feature at best. Perhaps someone will really like this, like return from DTL and coil porn to microcoil MTL experience. In the meantime, I can only offer to consider the facts: in 2018 there are still boxes with this feature, and there will be more.
    And the last, but not the least :rolleyes: Free ROM space is a strong focus on matters. Every time we decide to add support for new box or some functionality we weigh the pros and cons, and never offer to do what will lead to a complete impasse.
    The final decision is yours, on result of the poll. Dixi.

    How different would this be from stock firmware's bypass mode?

    VV is different from everything because the stability of the output voltage is not affected by the drop in voltage on the battery (bypass mode) and the oscillations in the small changes in the heater resistance (VW mode) , in my opinion VV is the most skilful pairing feeling in mechanical mode but without falling performance and my the voice goes for implementing this function (although some have prejudices that it is unnecessary or obsolete) ...

    if this feature would work in temp control mode, then i would be all for it to get it tweeked just that much more.

    I used VV mode for years - and for a long time after VW devices first appeared due to the horrific PWM the older, cheaper chipsets used.

    Since the chipsets became better, right now I am satisfied with VW and do not feel a need for it personally.

    (I can`t speak for other people of course who may find it useful)

    ~~~~~~~
    If it can be put into the firmware that would be OK too, if there`s room on the rom :)

    Yes, please add VV mode as it will give more accurate results.

    one thing to consider in favor of VV mode is health and safety, one should never vape above 4 volts as there is more of a risk of releasing toxic compounds as seen in this chart.[​IMG]

    LOL I don't think it's the size of the chart but the chart itself. Correct me if I'm @maelstrom2001

    the chart is from a study on safer vaping temperatures and how voltage can play a role, i didn't mean to offend anyone. the levels are still well below the level of toxins found in normal cigarette's so it's not anywhere near as bad for you. just wanted to inform others as we have more control while vaping than that of the old stinky's.

    toxins come from too high temperature. voltage alone doesnt tell at what temperature ur gonna vape.
    chart is just bullshit in every way
