Google is your friend, there are many options, here is one: https://www.protovapor.com/product/dna-color-screen-holder/

What board and what enclosure are you using?

I'm going to make another attempt to show how to set mod resistance. This can not be done on all DNA boards. Not with the 75C, 100C and 200 boards. It use to be able to be done with 200's but a firmware update stopped that long ago. Start by cleaning mod's 510 and the plug with alcohol. Using EScribe set mod resistance to Zero. Start Atomizer Analizer with mod connected and screw the shorting plug into the mod's 510. Put the value from Atomizer Analizer into the Mod Resistance box and upload settings

Do you see cell 3 and 4 are way above 4.2 volts, this indicates as far as I know that that battery management chip is bad. If under a year old you may get some help from Stealth Vape UK or perhaps Evolv. https://helpdesk.evolvapor.com/index.php?a=add&category=1

You have it set for "maximum recharges" , that is how I set mine when using a LiPo. If you want is to charge to 4.2 volts per cell set it to :maximum puffs. Maximum recharges stops the charge at 4.1 volts.

Be aware that the zero in the box is not the mod resistance, this is just what it is set to. Put your value in the box and upload to device.

I'm inclined to think that the mods with the lower resistance is closer to correct. I can't remember a DNA60 reading less, only higher. For sure zero is not the correct setting, usually 0.004 or higher. To check the mod resistance use atomizer analizer with a shorting 510 plug with mod resistance set to zero. Screw the shorting plug into the mods 510 and put the resulting figure into the mod resistance (electrical tab) and upload to device. I use a cartomizer that I soldered over it's 510 connection, it works great. This could be done also with a 510 to 510 adapter or an old atty with brass base/510.

This is an old video using an old version of EScribe but explains it well.

On this one the mod resistance is set to "zero", are all 5 mods set to zero?

What brand of mods do you have. Example: Dovpo College DNA60

With default settings red means charging and green is charging finished. Using EScribe's Device Monitor check the voltage on each cell and post it back here. Or better yet post a screen shot of Device Monitor like this one.

When using Atomizr Analyzer how many turns more does it take to screw in all the way once a correct resistance starts showing? There is no 510 standard so some are shorter and don't contact well with the mod's 510, check for that.

I see no resistance change when firing here.

It is normal for resistance to slowly rise when using Atomizer Analyzer as a vrey small amount of power is being applied. The resistance change in you previous post appears normal to me. It should be slowly going up, not up and back down and up and down.

It appears to not be stainless steel, probably Kanthal or Nichrome.

Hover mouse curser over area indicated by red arrow and report back what the voltage reads. Also it appears that the standing voltage of your cell is 3.66 volts, with a 75 ohm load it very well is going to drop to below the 2.75 volt cutoff and do exactly what you are posting about, throttling down. Does charging the cell to full charge correct this problem?

Post a screen like this. Note the voltage drop while firing is 3.76 volts on mine. What does it drop to on yours while firing?

If by chance that you have the battery type set to "Power Supply" it would not charge. Check to see that it is set to 3 cell lithium polymer as shown here: Also does the board fire?

Even though your charger outputs 4.5 amps the board will never draw more than 2 amps, so no problem. Pay attention to cell voltage rather than percentage, 4.1v - 4.2v is full charge. If they are not close in voltage between each other charging will appear to stop while it balance charges which is quite slow. One more thought, have you tried using a different cable?

On all your screens the settings look good. After you did the reset is it possible that it changed from 2 cells to 3? If so change it back to 2 and upload settings. You have it set for maximum recharges which is fine but charging wil stop at around 94% On your 1st screen those wavy lines are not good.

The best work around would be to lower the wattage down and take long slow hits.

As Bill said "batteries can explode" and those salvaged laptop batteries are of the chemistry that does it best. Laptop batteries are generally 4 to 5 amp continuous discharge rated. To supply 100 watts from the board cells with a rating of 15 amp minimum would be required. Personally I would use 30 amp rated cells. You are running a huge risk by over taxing them. If you want to salvage cells from something power tool batteries would be a good source, though I wouldn't recommend doing that either.

I had the same problem with the Windows version on my DNA60. James fixed it right away, try downloading and installing again.

I don't know, I'd be pretty exited too if an expensive mod like that malfunctioned.
