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

If you can provide us with a snippet like this we very well may be able to see what's going on. Perhaps tomorrow I'll set up a much lower resistance coil and see if I can reproduce it.

This is the version that I am using: https://downloads.evolvapor.com/SetupEScribe2_SP25_INT_ServicePack.exe

Here I have EScribe's Device Monitor open and a DNA60 connected. I have taken a puff and hit the pause button. Then by hoovering the mouse curser over areas on the graph it will show the values at any given point. Note my cell was at about 4.1 volts before I fired it at 45watts preheat then 35 watts. During the 45 watt firing the cells voltage dropped to 3.52 volts.

What was the voltage of the cells when charging stopped? There is a setting to stop charging at either 4.1 volts or 4.2 volts. Maximum puffs is 4.2 volts.

What did you do to solve the problem?

Have you tried other atomizers? Some 510's on atomizers are on the short side as there is no standard for them. Does the 510's positive pin appear farther down than usual?

That is the correct screen. Also can be found here: https://www.cremedevape.com/Evolv-DNA40-Replacement-Screen And here: https://www.modmaker.com/power-boards/evolv-dna-40d-60-75-200-250-replacement-screen

I have only one DNA250C and it does the same thing as in Retird's post.

The up and down buttons must be locked to use them to change profiles. To lock/unlock press both of them at the same time till it indicates locked/unlocked. With it locked press either up or down button twice to show profile. press up or down once to change profile. When desired profile is show press "fire" to keep it.
