    I am sorry, I removed the doc, and inserted the pics.
    My setup in my 3 different attys are quite similar (expromizer 2.0, Taifun GT II, Kayfun V3-clone), they are done with 316SS wire, single coint, and around 1 ohm. No matter which atty I try the result is the same.
    The fw version is 2016-06-05 (I also tried other one, but the results were the same).



    Your cold resistance is all over the place. Every time you post a graph it is different.

    Making a 1.0? coil is pretty uncommon. What gauge, wraps and diameter?

    Thanks Awsum. So something like this?

    As for current, I have a Melo 3 mini, and vape it at 50.6W/3.7V and have never gone over 13.x amps. Everything else I vape is between 15 and 25W at 3.7 to 4.2 volts (I never go over 4.2 or under 3.7), i.e. not 'hot'.

    I don't really want to throw a rotary on for "atty toggling" because it loses a bit of the cool factor to me lol.





    That is the same type of switch as the Honeywell you posted earlier, 3 position DPDT. You still would have to add the jumper that I showed you to convert it into a SP3T. The Honeywell being rated for more amps.

    Basically these switches have 3 positions. Both contacts up, both contacts down, and in the center position one set of contacts go up and the other set go down.

    OMG it is! Crap I didn't even notice that!!! Do you think that was the cause????? I'm an idiot!



    I would think that if the board was well grounded then all you would of gotten was an atomizer shorted error. And if the board wasn't grounded, it would work just fine backwards. So i'm leaning towards that not being the cause. 
  4. The added resistance for the switch would mainly affect temperature control. If the switch and wiring added 10 milliohms that is nothing for wattage mode but in TC mode it could be hard to compensate for because the resistance might change every time you flip the switch. 

    That switch you pointed out won't work. For a toggle you will need a DPDT on-on-on  Switches2_Diag_6.png 

    You could also use a SP3T rotary switch, much like Phil B "lazy box". 

  5. There are two parameters for the Big Question.

    • "The resistances are so close together that this must be the same coil, so we won't ask and just assume that it is indeed the same coil.  If we got it wrong, it won't make a big differance and refinement will fix our mistake." This parameter is user adjustable with the ohm lock range.

    • "The resistances are so far apart there is no way this is the same coil. We will just assume this is a new coil."  Basically it will take your original cold resistance and compare it to the new resistance and the TFR curve you are using. If the calculated new coil temperature is outside the vaping range, it will assume its a new coil. This parameter is not user adjustable. The cold resistance and the TFR curve are the parameters. 
  6. Continuously discharging a lipo to 2.8v could shorten the life of the pack. Considering that you said that you have never received a weak battery warning, yours didn't go that low. However there is no telling if you got it below 3v. The default CSV for lithium polymer has 0% @ 3.10v
    So if you stopped vaping at 0% and didn't continue past that, I doubt you did any harm. 

    I would use device monitor to track the 3 cell voltages under load. if you see a bad imbalance, then toss the pack.

    I'm not sure why you saw the battery meter take a big drop. Possibly you have the wrong Wh setting.   

  7. Weak battery warning is based off of the voltage of the packs. Battery percentage and battery bar are based off of calculated estimates of the watt-hours. You didn't ruin the pack by going to 0%

    18650s have more voltage drop than lipos. That is why you are seeing the weak battery message with those. It is important to set the proper Wh Capacity and Cell Soft Cutoff in Escribe for the particular configuration that you are using. 

    Maximum recharges sets the charge voltage to 4.1 volts vs 4.2 volts for maximum puffs. 


  8. You can also lock the resistance after refinement and after you have everything dialed in right. I believe it will remember the locked resistance without power. I don't suggest locking resistance right after attaching a new coil, because the temperature readings won't be as accurate unless they were mated dead cold.  

    You can also power the board with usb while changing batteries.
