It's 167 watts for the 250 with 2s

I've been thinking about this ^^^ for a while but have only a guess....here it be. After sleep the mod displays what the % actually is (the zero) which is derived by it's battery settings (Wh or battery CSV, or both). So if one/both are not quite correct the accuracy of end result will be off. I'm just guessing here...........

Here's the figures that I would use if it were mine: 23.50 watt hours 2.90 cell soft cutoff The figure to put into the calculator would be pack voltage which would normally be 11.1 volts for 3 18650s, perhaps 10.8 volts for 3 of those VTC5a's. I subtract roughly 12% from the Mah when using 18650's instead of lipo pack

I tested out my SDMY75 a couple of weeks ago with an Aromamizer running a couple Kanthal Claptons @75 watts. I use an LG HD2 18650. There was nothing scientific about my test and I noticed nothing unusual battery wise. It appeared to operate as one would expect a single 18650 mod at 75 watts. I thought it lasted much longer than I expected. Just saying.

I think it has to do with just what area of the world the person is at (non English browser perhaps). Try another browser, that worked for others.

I'm going to just have to guess at this one, I'd say the display just isn't keeping up with what the board is doing. EScribe will sort that for you when you get to it. Like I said , just guessing here.

Just exactly what does that screw actually do?

I do

My best advice would be to try a different web browser.

It's only going to ask when it doesn't know. I'm thinking that the temp is off, that probably has a lot to do with it also.

The battery that you have selected has a 25 amp CDR rating, the board can only pull 23 amps from the battery. The battery IMO seems up to the task.

You will lose the atomizer's cold setting with a hard reboot, your settings will stay.....not like default settings.

just upload to device for sure, perhaps a hard reboot.

What model 75's are they?

I calculate my watt hours a little different than most when using 18650's in a mod meant for a lipo pack, this is due to the built in (hardware) cell cutoff So I'm using Steve's battery CSV with a soft cell cutoff of 2.9 volts and 12.5% subtracted from the 18650's advertised mah. My battery icon as far as accuracy seems pretty good. But I'm using LG HD2's not 30q's. Oh BTW the hard cutoff on a DNA200 is 28.5 volts unless that got changed by a firmware revision......in case anyone is wondering.

Certainly nothing excessive going on there.

See if you can get a measurment of the voltage drop when firing in Device Monitor when firing with the batteries standing at 3.7 volts.

Looks be be time to open a ticket with Evolv.

Are you using SP3? If so perhaps revert it to this for getting the value of mod resistance then return it to SP3 when done. *** 2016-02-29 EScribe 1.0.42 *** Sorry, I don't recall the FW version but it's included with the Escribe 1.0.42

Have you tried charging with another USB cable?

Download the preheat.csv and add it to materials in the left pane of EScribe's materials then add to mod (right pane) and upload to mod.

That's because it is a DNA200, there is no DNA133 board, just the 200 running at 133 watts.

Yes, but the latest (SP3) covers all the Escribe capable boards.
