In EScribe check to make sure the correct battery type is selected, I'm thinking that it may be set to "power supply" It should be like in this image.

What does EScribe's Device Monitor say that the votage for each cell is when indicator is 50%? Being that they are in a series when used in the mod the amount of discharge is equal. Perhaps one cells is defective/weak

In my case the problem was on two identical new mods. SXK DNA60 Ionboxes. Two different colors purchased from two different places. What I did was to add a blob of solder to the positive contact on the cell. I did this for both mods. This needs to be done quickly and with a high heat soldering iron 100 + watts. I used silver solder and acid flux, same as for house hold plumbing the filed down to desired length. To see if this could be the problem with yours perhaps you could place a small washer between your cell negative and battery door and use Device Monitor to see if you get some improvement before proceeding to my method. The two screen shots that I posted yesterday were from one of these mods before and after my fix. The added length here is 1.5mm.

Use EScribe's Device Monitor to see voltage drop. Your Molicel P45B 21700 would be good for way more than 100 watts. There is a poor connection between the cell and board.....for sure. Here is my DNA100C with Samsung 18650 20S 30 amp cell with standing voltage of 4.0 volts firing at 75 watts. Note that the voltage dropped to 3.23 volts. It would continue to fire @ 75 watts till the voltage drop hits 2.75 volts.

Use EScribe's Device Monitor to see the voltage drop during firing. Here on mine the problem was due to the battery not fitting tight enough for a good connection. Poor solder joints or a battery with low amp output could also be the problem. Note if it drops below the Soft cell cut off the power will throttle down (2.75 volts in this case) Included is a screen shot with acceptable voltage drop.

A 4 cell 1600 mAh lipo is 23.68 Wh 4 3000 mAh 18650's are 44 Wh Quite a difference there.

The pinout on the DNA100C is the same as a DNA75C, here is a link to the DNA75C data sheet: https://downloads.evolvapor.com/dna75color.pdf

You may get your answer here but it would be best to also ask here also: https://helpdesk.evolvapor.com/index.php?a=add&category=1

The fire button is not using the fire button on the board, it's a separate little board with a switch on it, there could be a problem with it or it's wiring. The up and down accuators most likely press against the up and down buttons on the board, I'm surprised they don't work.

Does it connect to EScribe? In the lower right hand corner of Device Monitor is the option to press the buttons through EScribe. Do they work there?

Being SS316L it is an alloy which could vary wildly from the recommended TCR. Start by using just wattage to get an idea of how much wattage that it can handle going by taste the back it off some. I'm looking at your cold vs live ohms, give the TCR value a try for SS340 and manually adjust the SS430 value from there. Recommended value for SS430 is 0.00138, use SteamEngine's CSV file or what came on your mod for starters. This is how I would go about it.

Is the contacts for the battery clean? Try cleaning them with alcohol and cotton swab even if they appear clean. It could be a wiring problem like a poor solder joint.

18650 is the correct setting for your 21700 cell. Is the battery being held in it's holder tight enough?

To do it manually the value is 0.004. Select the mateerial to chancge, press the Temperature Coeffiency of Resistance tab and enter 0.004, then OK

The easiest way would be to import the included CSV file to EScribe, add it to the mod and make a profile with it. The value of this is 0.004036, (403.6) DNA200-Nifethal_52_(Alloy52)-SteamEngine.csv

I have two of them and they arrived with the same problem. The main problem is the battery isn't held in place tight enough. Using a100+ watt soldering gun I soldered a blob of silver solder to the positive end of the battery then took it down to 1.5 mm in height. This and a couple minor things fixed mine right up. Here is a link to a post I made over at ECF: https://www.e-cigarette-forum.com/threads/sxk-billet-box.898599/post-23558056 Read maybe 10 posts or so back for additional info.

Seeing that you are using wattage mode it isn't of much importance, you can simply adjust to wattage up or down a little. If you were using temperatue controled coils then it would become more of an important issue.

Of the 4 AIO DNA60 mods that I have the internal resistance is much higher than my other DNA mods. My AIO's read 0.012 ohm to 0.019 ohm. It would be a bit difficult for you to measure it so I'll skip that. Here's what I recommend, start with a value of 0.008 ohm and increase or decrease as needed, assuming that you know the ohms of the coils you mentioned above. Put the value in the box in EScribe mod/electrical and upload settings. You may have to reboot the mod in EScribe or by taking the battery out and back in to see your results.

If I were a betting man I'd say that it is 2.75 volts. The board is throttling down just as it should. Am I right?

Again I will ask, what is the voltage showing at red arrow? Hoover your mouse curser over the area and it will show the value. Maybe this will help, if you feel that your battery provides enough amps most likely the battery isn't being held tight enough by the battery door. It is most likely that or battery isn't powerful enough. What battery are you using?

What is the voltage dropping to when firing? EScribe Device Monitor will show this. If your cell isn't powerful enough or the battery sled connections are poor and the voltage drops to 2.75 volts the wattage will throttle down. Below mine dropped to 3.29 volts when firing.

What does EScribe's Device Monitor say for the voltage of each cell. They may be out of balance causing the charging to stop when one of the cells reaches 4.2 volts.while the other one is still low.

If DNA250 it should be the two center ones. #2 positive and #1 negitive for cell #2 connection

I used a small gauge solid wire, no tinning. Made little circles like elecrtic stove burners for on the ends of the 5 ml juice bottle and simply taped the wire to the side of the bottle. On the battery end I just pushed the wire into the holes on the JST plug and added some tape so they would stay put. Use your meter to find them, they will be next to each other.
