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)

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

Did you solder tabs or something to the ends of the wires going into the charger? How did you get the other end into the JST? I feel like stripping a good enough amount and tinnijg it would be good enough, but I'd be interested to hear how you did it.
Also - if I'm trying to charge cell 2, I'm going to be using (starting nearest the battery negative) the 2nd hole as my negative and 3rd hole as positive, correct?
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.

The battery in my post had been hooked up to a small hobby charger and an expensive one with no results.
So just what is your concern with my recomended method?

It just dropped from 67 to 66 while plugged in. That's not charging.
It has to reduce the cells that are full charge in order to bring up the low one, this is done with very smal resistors.

There is an option under the Tools tab / Diagnostics/ USB Recovery that will prompt balance charging.
-
That's the balance charging doing it's slow thing. If you can implement what I posted it will get it up in like an hour. Once balanced use EScribe to see that cell #2's voltage drop when firing heavy load matches up with cell #1 &3.
If not then maybe defective.

What were the 3 voltages when you first installed it?
I should have said "was it out of balance to start with?"
-
Probably a couple of days.
EScribe will show a charging rate, low but charging non the less.

In this image I used a juce bottle with wires taped to it's ends and placed in a charger. The wires run to the balance plug and connect to the low cell. While this may look a bit crude it worked very well.
If you don't want to wait till it balances via mod consider this.

It appears to be balance charging, it's a slow process. It should get there eventually.

I torch all wire with the exception of Ni200 prior to winding. Then glow them after installation before installing wick.
-
Are you using the same wire as in your earlier posts? The resistance of 0.12 troubles me. With building the same coil with the same wire but 6-7 wraps instead of 10-11 should be around 0.21 ohms for the pair of coils. Is there any chance they are touching the chamber? Have you checked resistance with the chamber removed, deck only?
-
Let your coils cool and use EScribe's Atomizer Analizer to check resistance.
-
316 316L are so close.
So it says 0.4 ohms, is that per coil or total. My experience says per coil.
Weak Battery Error

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