    Would be awesome if I could run my rx200 in dual battery mode

    AFAIK the Rx200 is wired up in a way that its not possible for it to work with only 2 batteries.

    Wow. Maelstrom2001, would it be theoretically possible for a hobbyist with a little bit of a crazy streak to use that extra space for a dangerously large capacitor, and actually turn one of these devices into a powerful, even potentially lethal stun gun? I would personally hate to see this happen, it seems like it would be bad for all vapers, but given that there are already plenty of videos showing how to turn a disposable camera flash cap into a very unsafe type of DC stun gun, I am almost waiting for a headline about school kids making some kind of game out of dueling with deadly ecigs or something...

    @Rassledazz Why do you have such strange suspicions? Perhaps our friend just want to upgrade RX to squonk. Think positive (c)

    Oh nonono I did not mean to imply any such thing, and I apologize to Cloudasaurus if my post came off as accusatory. Especially based on his handle, I think he only wants to puff like the rest of us :)

    I ask this in general, because of the amount of power the industrial batteries have put into the hands of millions of vapers. Not that $9 stun guns aren't already easy to get, but they aren't deadly, so I've been a little scared that someone would release a simple video or something that could turn the public against our favorite toys. Hopefully it never happens, but I thought I would ask your opinion about the possibility.

    How are the battery voltages displayed? Look at the main menu -> Info

    Are voltages displayed correctly if you install all 3 cells? I'm asking because switching to dual battery mode is based on voltages reading (sincerely your Captain Obvious :D). If box see voltage above 2.50 volts on cell 1 and cell 2, and less than 0.20 volts on cell 3, it should run as RX2/3 in dual battery configuration. In your case voltage on cell 1 is reading overestimated, and cell 2 measured < 2.50 volts. The box does not understand what it should to do, and it stays in 3 cells mode.
    The sum of cells voltages seems to be correct, so we can assume that ADC 2 (battery 1 + battery 2) working properly. But result of measuring on ADC 1 (the first battery) is totally messed.
    Maybe it is the answer why it is not enough to short the third battery holder as it can be done with RX200S?

    Can confirm that this firmware is working perfectly in 2 battery mode with the 3rd battery bay bridged out. thanks so much @maelstrom2001 can finally do the squonker conversion. thanks

    question: i updated my rx200 to latest nightly build, how i enter dual battery mode? if i remove one battery and try to start up, it doesn't turn on. And, why i should run this mod with 2 batteries instead of 3? thanks =)

    Some people like removing one battery so they can do a squonk conversion
