    In an UNREGULATED mod, the battery life would be the same between a series cell configuration and a single cell configuration and increase with a parallel cell configuration.

    In a REGULATED mod, Dual Batteries, whether Parallel or Series, WILL give you more battery life than a single cell mod, WHEN using the same Coil and Power/Wattage on either mod.

    After further investigation, I concede that you are right and I am wrong on the point of battery boxes being mostly series wired. There must indeed be some seriously dark magic going on for the chips to convert the energy flow the way they are doing. Every thing I know points to the basics, yet these mods are doing the opposite.

    The below even contradicts what we have been discussing

    BATTERIES IN SERIES
    [​IMG]Essentially this means your battery terminals connect positive to negative.

    The combined voltage of the two vape batteries in this configuration is the sum of the individual batteries. This basically means you’re increasing the voltage of your battery supply when using batteries in series.

    However, the current (mAh) and Continuous Discharge Rate (CDR) is that of the single battery.

    The advantage of this setup is that it provides additional voltage and greater power to the coil, increasing vapor production!

    BATTERIES IN PARALLEL
    [​IMG]The opposite of batteries in series, your battery terminals connect positive to positive and negative to negative.

    The combined voltage of the two batteries in this configuration is that of the single battery. The current (mAh) and Continuous Discharge Rate (CDR) is the sum of the two batteries.


    The advantage of this configuration is to enable increased (twice the capacity) current. This will result in the combined battery current lasting twice as long as that of a single battery. In layman’s terms, your vape mod will run for double the time before you need to re-charge the batteries.


    Furthermore, the CDR of each battery is doubled. This can have two possible advantages:

    1. With two batteries, each having a CDR of 20 Amps, the overall CDR will be 40 amps. This will allow for a lower resistance coil build, enabling higher current to be drawn from the combined batteries.
    2. If your coil build and battery voltage is such that the current drawn from the combined batteries is 20 Amps, you can use two 15 Amp batteries. This means you can use two lower spec batteries to achieve your required CDR value for your vape build.

    So based on the above research, we are right when it comes to unregulated mods but wrong when it comes to regulated.

    Spot on :talking:

    I'm grateful for the info ... Thanks everyone
    I posted the statement "I'm curious as to why the proliferation of Series Dual and Triple Battery Mods, and not Parallel Dual and Triple Battery Mods in the market", as I'm busy with an Arduino Nano powered TRIPLE parallel build, that's now about to change to a series triple mod, as that also resolves my need for a separate buck/boost circuit for the processor, (5V required for the processor).

    Okay now that we have sorted this little debate out can we now tell @Dela Rey Steyn to stop chain vaping himself to death to get us a practical demonstration of battery life in his single and dual mods.

    The poor guy is gonna get a nic overload.

    For the love of Gawd then let's not start a thread about how sensitive vibrators can get... Given this mans dedication to the cause I can just imagine what will happen

    According to me an unregulated series mod wil convert energy from volts instead of Amps
    And vise versa for an unregulated parallel mod.
    But that's according to me.

    Just a slight correction.

    We don't recognise descriptions like nic overload.

    It is called doing a Silver.

    For those of you who don't know about this @Silver became infamous for doing this when he was a noob.

    After reevaluating my experiment parameters. I started a fresh with a lower build on my Rebirth RTA and 3mg Taviro, which from experience I know I can vape on the WHOLE day.
    Drag X:
    Started with a fully charged Molicel Battery and reset the puff counter.
    It picked up the atomizer resistance as 0.2ohm

    IMG_20200929_085323.jpg
    IMG_20200929_114445.jpg
    Reached 174 puffs before the battery indicator turned red.

    Argus GT:
    Started with a fully charged married set of Molicel Batteries and reset the puff counter.
    It picked up the atomizer resistance as 0.21ohm

    IMG_20200929_122145.jpg
    IMG_20200930_052000.jpg
    Got to a total of 332 puffs before the battery indicators turned red.

    I think I know how they are doing it.

    In the same way that the chip will allow for balanced charging through the USB, I think that they chip is also compensating for a balanced discharge from each cell. This would not work if they were simply stacked like a boom stick, but now makes sense.

    I have seen a few comments on mods where the battery indicators on a dual are not discharging at the same rate and when the one is empty, the mod will not fire even if the other one reports full. This then explains that if that function is not working correctly, you will not get the balanced discharge. In effect it separates the batteries then reconnects them drawing only what is needed in terms of W and amps. Push the Volt demand over what the battery is capable of, for example you can't get 5 V from a 3.7 V battery, 4.2 at the most and then the dual batteries will combine to supply the required Volts.

    It is just a theory, came to me in a dream last night, just before the two Japanese models.

    This thread reminded me of something sort of related that I've wanted to discuss. Should probably start a separate thread though.

    Do you intend to stop vaping if you get pregnant? IMO this would be essential.

    Were said Japanese models battery powered? ... and if so ... Were they Parallel or Series? :clapclap:


    What I have seen on an oscilloscope is that the full battery voltage, (minus the miniscule voltage drop over the mosfet and a low value resistor that is used for current measurement/ feedback to the processor), is available on the 510 connector ...
    It seems the processor measures the current via voltage drop over the aforementioned resistor, and then adjusts the pulse width. So technically you have much higher voltages and currents at the 510 connector, albeit for short pulses, giving an average voltage / power much lower than the instantaneous values.
