    Take a good look at where the pins from the JST connector are soldered to the board,perhaps just go ahead and re-solder them.

    Can you measure the main power to the board with a meter while firing. Is the a plug on the main power leads?

    Measure the main power leads too while your at it. (on the board)

    Just a question, are you using the same cells to power the test setup as used in the mod? My 250C dropped 7% in just under 3 days just sitting which I expected.

    So I deceided to try to duplicate this problem. Here is what happens for me. I'm using a profile and change it to another and select it with the fire button. But if I don't fire that new profile and remove and replace the battery it reverts back to the original profile. Now if I fire the new profile and remove and replace the battery the new profile stays put.

    This option is for 100C and 75C only

    I see no problem

    Here is one of mine firing dry. Don't expect to see the temperature message on the screen as that isn't going to happen on a color board. On yours and my dry fire power starts at 25 watts and drops to 1.25 watts, temperature protection is working as it should.

    Is that with a wet wick or no wick at all? Preheat looks to be high, turn it down or off.

    Could you post a screen shot firing your coil like this one?

    I suggest that you contact Evolv Help Desk for this one. https://helpdesk.evolvapor.com/index.php?a=add&category=1

    Please show us a screen shot like this of Device Monitor to see the voltage of each cell.

    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.
  23. dwcraig1
    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.
