DNA 30 battery voltage issue

[SavageClouds]

So I have two dna30s one fires my atty at 4.1v and fires like a champ, take the battery out put it in my other dna30 out the same battery in it only fires at 3.2v and fires weak.. Both devices are set at same wattage, same atty, same build.

I've tried multiple batteries all result in the same thing

Same exact build....same battery holder, wiring, etc???.....Pics of both???

 

[SavageClouds]

Yep everything is the same bap.. Only have one with me at the moment so I can't get pics of both

I suspect a cold solder connection. Does the atty resistance show the same on both dna's?

 

[SavageClouds]

Yes the atty resistance shows the same on both mods.. Where would the cold solder possibly be so I can test

Is the DNA showing 3.2v when the fire button is pressed? Or are you measuring voltage somewhere else?

DNA is showing 3.2v when the fire button is pressed

Then I would say something is likely off on the output or the atty/coil causing the ohm to change. But you should see the ohm change on the DNA screen as well.

Hmm.....weird....

Well I know for sure it is not the atty/coil because I have used different attys I own to see if it makes a difference and the results are the same...


How would I check output?

The DNA needs to see a load to output, so an atty needs to be hooked up. Then you can use a dmm somewhere on the output +/- and see what it reads while firing.

Just curious....what ohm coil are you using?

Sounds like a bad a board. Contact Evolv and I'm sure they will get you fixed up - Evolv LLC - Contact

Tried an atty with a 1.0 ohm coil and one with a .5

I will most likely have to order another board seeing as how this one did not come straight from evolv

I had the same problem with my Hana V3! I didn't have two devises like Savage, but my dna 30 won't fire above 3.2 no matter what build I had. I tried everything......switching batteries, testing with a fluke mater and still 3.2. I called Hana and the devise is on it's way back. Should be there by tomorrow. The owner said it might be a bad board based on what I told him, but he want to check it out. I'll post his findings when he gets back to me.

Contact them anyway and explain the situation. They have great customer support, plus your not out anything trying.

I actually talked to Evolv and directed them to this thread. They said based on the info provided that it sounded like a bad board.

Grat baps. Ty for the help. Greatly appreciated

Hey guys,

I told you I would update this when I heard from Hana about me having the same problem. Hana's response was that it was a bad board. I'm hoping that is doesn't become a habit for all the DNA 30 boards.......
