Did you also consider that Ni200 from room temperature doubles its resistance when heated to about 400°F?

I haven't seen one for the DNA75, but it is really easy to create one. Ohm's Law is all it is. Take the max current for whatever wattage and then do another for max voltage. That will give you your answers. Here is one for the DNA200, but the right side one is the two cell configuration. So the max voltage column should be the same (max R), but the DNA75 only puts out 30A max right? So the min R column is the only one that has to be adjusted.

How stable is your Atomizer Analyzer? I quit using SS before I got any DNA200 mods, so I don't know what it looks like or acts like. I do hear that the newest firmware (which isn't released yet) does SS TC a lot better.

Oh ok.

Huh? This SolidWorks? [video]https://www.youtube.com/watch?v=-kzhOjsiVY4[/video] SolidWorks 2015 opens up DNA200 files? Using what file extension?

I should add with the lipo battery it should be on 3 cell and for the sled, two cell.

Yes I figure that panel has to come out. But I don't know if it is snug in there or not. Gently press on the buttons and see if it moves at all. You can try plugging in the USB cable (not connected to a computer or anything) and push very slightly and see if that moves. Be very gentle as the switches and USB port is delicate.

It sounds like to me that it was set for three cells and not two when you tried the battery sled. Thus it saw the three cell as 0v or something. And yes you can troubleshoot this under EScribe and if you open up the Device Monitor, it will show you things like cell voltages and such. Be careful about the upload button under EScribe. Because you can loose important settings. Once connected to EScribe, do a File -> Save first and then no worries since that saves everything if you connect and download from the device.

I am not having any luck on the Internet in how to take one apart besides changing the battery.

If there is juice in there, those cell readings could be way off anyway. You don't have a multimeter, do you?

Well yes, it could be juice in there causing all of this. I still don't know what that green stuff could be on the battery connection. I also don't know enough about the insides of the Lavabox (except how to remove the battery). So I don't know what it takes to get to the board. And yes, a proper cleaning could indeed correct everything for you.

Now I am getting concern. How warm is it where you are at? Device Manager states it is in the 90's there? Is this correct? And if possible, I would try to get all of the cells above 3.2v. And try the same with the other lipo. I also wouldn't leave it alone and touch it every few minutes to make sure it isn't getting too hot. If you can get this far, remove the battery and contact Volcano and get a RMA started. I am serious, I wouldn't trust it alone with batteries installed or plugged into the USB.

Did you even charge the battery after receiving it? Off of the assembly line, lipos are usually about 40% charge. This is also the recommended charge state to store lipos. Although they lose 1 or 2% of their charge per month. It seems like at least your cells started out high enough because the DNA200 won't let you fire it if it wasn't within specs. Charging low cells is kind of tricky. I normally wouldn't do this for more than 10 minutes. But that is in EScribe and in the Device Monitor, Diagnostics (button), Advanced, and then Perform USB Recovery Charging. This will attempt to charge up very low cells which normally won't be chargeable.

I could, but what good would that do? Evolv had taken it down for some reason and maybe because it has a serious bug or something. No word on why yet. But if you want to run it because of all of the DNA75 features and use them on your DNA200, it doesn't work that way.

What do you think Mike? You really entertained the thought that Evolv will cease production on the DNA200 and just go with the DNA75?

That is what it looks like after running the latest version of EScribe. Although the earlier versions doesn't look like they will work with the DNA75.

Well who knows... maybe that will be a feature in the next firmware.

I can't think of anything except globally, but you knew that right? Like you can set it for 50 watts max. It does remember the last wattage you used per profile though.

I noticed for your first post, you didn't bother asking the easy questions first. Why would you think this? All quality ohm meters always nulls out its own internal resistance. And how would TC work if it didn't know what was the TC resistance vs. the static resistance? What am I missing here?

We vapers don't normally use the low end of the last capacity since battery power is really weak there. And watt hours is generally calculated using the full capacity. So you could cheat a bit and lower the watt hours.

The battery percentage is only as accurate as the calibration (the user can do this too). If it is off a little, the percentage will be off a little. After charging, are the cells either 4.10v or 4.20v? If so, then they are charged up.

Yes I like it very much. Where can I get one? Even just the box alone (I am not crazy about the color though)?

I guess we should tell Thea Queen what the difference is between maximize puffs and maximize recharges (under the mod tab). Maximize puffs charges the cells to 4.20v and maximize recharges only charges them to 4.10v. Charging them to 4.10v is supposed to make the battery last longer. But at a price of slightly lower battery capacity.
