    Is this safe?

    Been killing time building and rebuilding heads and tanks. Finally decided to try out paralleling kanthal in a RDA.
    As I was switch from TC to power mode I went past bypass mode and noticed this.


    Is this safe? If so what isn't safe?

    2x 24G kanthal 5 turns.

    Now gonna wait till head spins wear off.

    Bypass Mode is a direct output mode of voltage. This mode can only be used with atomizer resistances under the range of 0.15-3.5 ohms; otherwise the device will not work properly.

    I don't know enough about bypass mode but my guess is thats going to get real hot real quick. Why not just stick to POWER mode.

    Maybe the more exp dudes can answer but its late so i might have to wait till tomorrow.

    I'm not quite sure what you are asking? Is bypass mode safe or that resistance or what?
    To my knowledge you are essentially vaping a 0.12ohm build on a mech mod which I wouldn't personally recommend
    ....especially to someone who isnt all that experienced.

    That would not be safe on a single battery at all, but even though its bypass mode I really doubt it would actually output what it says it is.

    Yes of course. Good point J_B_86. For some reason I was thinking the minis ran on 2 batteries.
    Still wouldn't recommend it on 2 unless you really know what you are doing.

    Well it's a "all of the above" question.
    1) Can a wire build take that much current without wire going boom.
    2) Would juice catch alight like it does when I dry burn coils to clean.
    3) is the mod gonna go bang
    4) is the battery gonna go bang
    5) well...is anything going to go bang when I'm on the end of it.

    In the end I pulsed it tentatively, opened airflow to the max and took several quick hits.
    Nothing went bang and the only difference was vapour was produced much quicker than on 75w.
    As to the vape itself, I pulled like I was using a power breather and not longer than 2s but still it was very warm.

    And I agree with JB, the coils heated faster and there was more vapour but not close to double as much.
    Given that, I'll be leaving that mode alone until I know more...

    Well even though I don't believe it can, lets say theoretically it was able to actually output 143w...

    1. Yes if it is thick enough and there is enough of it.
    2. It could if the coil diameter was too small and couldn't hold enough juice to keep it wet, or a tank was not able to wick fast enough to keep up.
    3. No but overheating it could fry the chip or see 4.
    4. Its certainly a possibility, most likely it would vent rather than go bang which is still quite violent and hazardus, mod would be ruined in the process.

    Thanks JB!
    I probably shouldn't have fired it until I got advice.

    Here is the build:
    I did 5 turns of 24G kanthal running parallel. 3.0mm shaft on tool.

    The atty didn't get too hot but the battery did.

    I guess bypass mode is meant for builds with more resistance.

    34.5 amps...........................Does that sound safe..............................

    Always check ohms law before firing low ohm builds.

    Haha yeah I ran that through this morning. Wire covered in juice looks to be yes. Lithium battery...no. I have LG HG2 which maxes out to 20A continuous load

    The fact the battery is still here strong suggest it never got that high or even in bypass mode there is still a safety limit or I was plain lucky having fired in very short durations. Not that I'll be pushing luck any further.
