Yes you can simply use the CSV file but you also can manually add it as indicated here: By using the "Action" tab in lower right corner.

Wire that changes the most resistance when heated work best. Go here to see TCR values: https://www.steam-engine.org/wirewiz Use the drop down menu to change wire type. Read the value in "TCR in Vaping Range" Note Ni200 is 6000, that would be 0.006 for the DNA TCR setting. Personally my wire of choice is SS430 which has a much greater resistance change than SS316.

Does the battery cap screw in? If so try cleaning it's threads and the corresponding threads on the mod with a q-tip and alcohol. Look down inside using a light and see if the positive battery contact looks clean.

My guess is there is a problem with the wiring between the battery and board. Look first at the battery contacts. Does the battery fit snug? There may be a cold solder joint where the wires solder to the board. Does the mod use a ground wire from the negative side of the battery to the board or does is use a chassis ground? Is is not because it's a 21700.

And make changes.

You can load various mods into EScribe without connecting the actual mod. Just pick one from "Edit New Settings"

The 18650 battery setting is correct, it more or lees just means round replaceable type cell. The Cell Soft Cutoff is set at 2.75 volts normally with a round cell. What is the standing voltage of the cell when it reports 40%? Can you post a snippet of Device Monitor firing under the conditions described in your post like the one below? Note on mine the voltage dropped to 3.52 while firing at 45 watts. Had it dropped to below 2.75 volts the low battery error should display.

There is probably a firmware update for you in Escribe. It with tell you when you connect if there's a newer one available Windows only for this version .https://downloads.evolvapor.com/SetupEScribe2_SP25_INT_ServicePack.exe Or for SP24 here: : https://www.evolvapor.com/escribe availible for Windows, Mac and linux

Are you saying that both mods work now?

For what ever reason the battery power isn't making it to the board.

Does the board and screen turn on with power power applied vis USB?

Well are the batteries installed with correct polarity? And does the battery door's little spring loaded pin appear to connect to the brass plate on the battery door. I would suggest connecting to Escribe and use Device monitor to see what is says for the voltage of each cell. Check if it reports one cell is above 4.2 volt and the other is real low,

Is that three different mods of the same model?

My DNA100C has an 18650 Samsung 20S (30 amp) at 90% charge here. I don't have any Kanthal or Nichrome heavy enough to get really low resistance so I used some dual core SS 316 Claptons in dual coil configuration. Both firings was with the screen timed out (off)

Did you change only the theme or did you use my ecig file?

I don't think it a bad connection as far as wiring, more like the board it's self. This is just my opinion as I am not an Evolv tech. My advice would be to contact Evolv's Help Desk and they will advise you as to how best to proceed. https://helpdesk.evolvapor.com/index.php?a=add&category=1 Add a link to this thread on your contact request.

The voltage drop looks to be not the problem. If it was a faulty cell or poor connections between the cell and board it would show in this picture.

With a fully charged battery do this again and hoover your mouse over the area of the lowest voltage drop and post it's value, do this with your Samsung 40T. You should not be getting low battery message firing at 70 watts with a full charged 40T unless your voltage drops below Soft Cell Cutoff and that would be 2.75 volts in most cases.

Here is the .ecig file that shipped on my DNA100C Give it a try if you wish, you can always revert it back easily. File/open/choose file/upload to device. Evolv DNA100C stock.ecig

So what theme are you currently using?

No but I was running your .ecig file and could not reproduce the problem.

What was the standing voltage of the cell prior to firing?

This is in reference to the coil in the video (0.16 ohms) It will take a good high amperage cell with good battery sled contacts to achieve 100 watts with that coil. I left out the one were it calculated to 4 volts but that's what it came out to. https://www.the12volt.com/ohm/ohms-law-calculators.asp
