I don't know what the hardware cell cut off on the DNA250 board is, I have asked but not got an answer yet. On the DNA200 board the hardware cut off is 2.85 volts, this is under load. The board is intended to be generally powered by a lipo pack so the cell cut off is higher than it would be for 18650's. I wouldn't be surprised if the hard cell cut off is the same on both boards. My estimate for your watt hours is 23 - 24. For a DNA200 board powered by 18650's I use 2.9 volts soft cell cut off and 3.09 with lipo. Running Battery Analyzer will give you the proper figures if you wish to do so.

A couple of questions. What it does Escribe Device Monitor show for cell voltages? Is your battery set for "maximum puffs" or maximum recharges?

It seems this is unknown, maybe Evolv can set us straight on this. What is the hard cell cutoff on the DNA250?

Mine ask when necessary with SP3/4

That is the spot on the board but how are you going to attach to the 510? You might check the 3 board mount screws to assure they are tight, they supply the chassis ground. Be extra careful not to over tighten and break them.

Up top in Escribe, options/user interface/ manufacturer. Or scroll to the lower part of the page if already set to "manufacturer"

Sure you can, it's exactly the same way only you lock the temp instead of power. Check it out.

Sounds to me like perhaps the nut that holds the 510 body into the case may be loose. https://youtu.be/g5fwz_SsqIU @ 23:40 there is a good view of it.

To change profiles start with fire button "unlocked" Press and hold the + and - buttons at the same time to "lock power" With power locked press the + or the - two times quickly and the profiles will change by pressing the + or - Perhaps re lock power when done...by pressing and holding the + and- at the same time.

I'd say you are on the right track with it but if it's got a warranty....well you know..

So I hooked my SDNA75 up to EScribe without battery and it jumps quickly back and forth from 3.78 to 4.10. Not that that's of any help I guess.

The DNA75 has no fuse but does have reverse polarity protection built onto the board. Not trying to be a wise guy but are you sure the battery is being inserted with the correct polarity?

The DNA250 will not power the screen without battery power as it's siblings does.

On the profiles that are currently using the material that you are wanting to remove from the mod.....switch those to another material then you can remove that material from the mod.

It must be removed from any profiles that are using it first, just switch them to another for the moment. Be sure to upload settings for it to be changed or removed.

I'd open another ticket and include a link to the above post.

It took some digging but it appear to be able to discharge safely to 2 volts.

I savage small screws from old computer devices, floppy drives and IDE laptop hard drives prove to be a good source. For sure they are metric.

Most likely your batteries are not up to the task or their connections to the sled is poor. What batteries are you using?

This post may be of some interest to you. /topic/66851-topic/?do=findComment&comment=901399

Well I was wrong about Device Monitor showing the fire button if pressed,it shows the up/down but not fire. I tied it just now.

EScribe will show if the button is working. If you decide to put in the 250 be sure to open a ticket with Evolv on the 200 board.....or open one now on what you have. https://helpdesk.evolvapor.com/index.php?a=add BTW, it's small stuff but most of the button can be disassembled/assembled (the button cover, button, disc)
