Hey gurus,
I just put a dna 200 chip into a boxer style case I got off shape ways. Other than being a monumental pain in the butt to get it built in that tiny space, I have an issue when I went to fire it up.
I should note that this is a dual 18650 build, and I updated the software and set it to run 2 cell as well as inputted my battery info.
So like I said, after I did all final wiring and installed 2 freshly charged batteries, pushed the power button and all I get is the initial power on screen and then it shut down. Every time I push the power I get that screen and then after doing it 2 or 3 times I get no screen message at all, just dead. . I looked everything over and nothing seems wrong. I did several power on cycles before I did final install and never had an issue. I tried to connect to escribe again after this and it wouldn't connect. Any suggestions? I'm new to modding but I followed all instructions and wiring diagrams properly I think. Thanks. Sorry it's so long

This sounds like the behavior seen when a cell is too low to power the board on fully, or the board cannot see the voltage of the cells due to wiring, etc.

At the 4 pin balance pinouts, did you bridge/short pins 2 and 3, and run pin 1 and GND?

. On the balance connector pins from left to right, left being ground I did this. Ground went to b neg , next went to the bridge on the battery tray that connects the pos to neg then the 3rd is connected to the 4th and the 4th connected to b pos

I did have to move the lead at the pos-neg bridge to make room during install. I might have not gotten a good connection when I moved it so I'll check that also.

Did you ever get this worked out? I am having a similar experience with my dual 18650 setup.

You have to run series via jxt. Make sure during charge stage you set it for 2 cell lipo. I've ruined batteries with wrong charging also try setting the cutoff at 3.5v.

Thank you, for the reply. My issue turned out to be a short in a wire going the negative battery terminal.

I just built a DNA200 dual 18650 MOD as well. The first time I tried to fire it up it up before I had it in the box the screen would say DNA200 and shut off. Did that a couple times then nothing. I went in to escribe to restore factory settings. When I did this it said I had to upgrade software to do the restore. I did that. Since I did that it doesn't do anything. When I have it plugged in to escribe monitoring/diagnostics/button simulation it says locked click 5 times no matter what I push. Last time I did it It was letting me change the voltage and said check atomizer when I hit fire. I wonder if the fire switch is bad? I tried on board and a separate fire switch. Any help would be appreciated. This is so frustrating. So close to finishing this MOD and then ran into this road block
Edit. If I click fire 5 times in diagnostics mode in escrow it unlocks and appears to be working. Could it be a bad onboard fire button?

since you're running the dna in dual 18650 mode, do you have "2 cell" selected in escribe under "manufacturer settings" and uploaded into your mod? are you 100% certain you have the battery wiring correct? specifically the balance balance taps. try re-flashing the firmware. make sure it's a recommended FW version.

Yes, I changed it to 2 cell and configured it just like the noname boxmods tutorial video did with escribe. I have the tabs on the groves in the Whit connector pointing down. I have grey to - on battery 2, the blue to the + side of battery 2 which is bridged to - on battery 1. Then I have white and purple to the + on battery 1. Then I have b+ going to + on battery 1 and b- going to - on battery 2.
The fire switch on the actual board doesn't work when it's plugged into escribe but in and down work. If I go into troubleshoot and use the onscreen buttons everything seems to work perfect. I'm wondering if the fire button on the board is bad? My soldering iron was acting up so I may have got the board a little warmer then I would have liked but I'm a decent solderer normally and all my connections look good to me. Been soldering building rc trucks boats and hell's for years.

Got it set to 2 cell lipo cap 16.8wh soft cutoff 3.2v. Left everything else alone I think. Accept changed kanthol limit to 130.

Any help is greatly appreciated. I'm banging my head with this after spending a day and a half building it and now I can't get it to work no matter what I do?

Just noticed the flashing part. How do I do that just upgrade software? How do I choose the version or know if it's a "FW?" Version?

does it connect to escribe? if you unplug the battery completely (balance tap and mains) from the board and connect to escribe can you reflash the firmware, then reconnect your battery and see if it stays connected to escribe. just make sure you press 'upload settings' after changing any values or fields in escribe. here's the correct wiring for 2S. as for the fire button not working if the just the fire button is truly bad, the pads for an external fire button should still work. you could always open a help ticket with evolv from their website for an RMA.
