  1. Here is my DNA250C with two 18650 Samsung 20S cells @ 67%, 3.8 volts per cell standing at start, firing at 120 watts.

    Cell Soft Cutoff is set at 2.75 volts so no throttling should occur till cell voltage drops below that. Battery sled contacts are clean.

    Here throttling would start at voltage drop of 5.5 volts and it's only dropping to 6.57 volts.

  2. So I just happen to have been getting ready to do a dry burn on the coil of my Insider that I'm using in an SXK BB last night before work (as I was reading your post). I used AA with the BB to check resistance while cold. I then screwed the Insider onto my SDNA75, it makes an excellent connection on the 510's center pin. I then checked it with AA and it was almost the same, just a fuzz higher. The SDNA75 uses a ground wire from the board to the 510.

  3. I use SS430 but note there are 3 different values shown for resistance. My screen shows .51 ohm., the top number is current resistance. When atomizer analyzer is active it applies a very small amount of current to the coil. If you are using Kanthal or Nichrome the nominal value is for that. But for setting mod resistance use that top number.

  4. I have adjusted the battery curve with this CSV, this is for charging to stop at 4.1 volts per cell. It is adjusted to show 100% charge at 4.1 volts per cell. This is how I do all my Lipo powered DNAs, the battery will have a much longer life. Save your battery CSV first and give this one a try, you can always go back. Remember to upload the settings each time that you make a change and want it to stick.

    Edit: Be sure to change "Maximum Puffs" to "Maximum Recharges and upload settings.

  5. You should still be able to apply service pack even though it's not connected to EScribe, it does still need to be detected by Windows though.

    Just apply the firmware update just as you normally would. Check in Window's Device Manager to see if Windows detects it. Then again maybe that's what your already saying that is not happening. There are some USB 3.0  controllers out there that seem to not get along with DNA boards.
