There are indeed a lot of bad boards, but we don't know what that means in terms of a %. Initially we were seeing a lot of installer error, but that seems to be getting better as well.

My guess is at that low of a resistance, you have some variable issue in your atomizer that may be changing resistance as it heats up and that small change is viewed as a large percentage of change due to your low resistance coil. To test this, make a build that is near .3 (like a single coil Ti build) and see if you get the same effect. I bet you wont as the atomizer shift in resistance will not be enough of a % to through off the vape.

The battery and atomizer hookup wire is pretty large gauge, if tinned heavily, and then bent to fit into the case, it can put a great deal of torque on the chip, and lift a pad. It is really important to not tin past the solder area and to generally shape the wire for its final form prior to tinning and soldering.

How about an image of the board, especially the balance port soldering and the four resistors to the right of the USB plug prior to sending it back?

There is a new version of VB out. Anyone try it with El Capitan?

VB released a new version this week. Any reports of it working with El Capitan?

Use a known "great" usb cable and try USB recover charging at least twice. Otherwise, it looks like a classic back pack.

It is a documented issue, though rare. They will take care of it no doubt. I have only seen two on this forum but it was described as the chip not being held in place properly during a pass through the soldering process.

I would plug in another pack and test. Likely a bad pack and an easy fix.

The pack is below what can take a charge. As scoopy mentioned, try the recover option (you may have to try it a few times) or replace the pack. Is it new?

Not yet.

Most measurements in my experience are with the wrap...i.e. as the pack will be used. You can remove it, but if one mm of shrink wrap makes or breaks your install, you have very little room for failure. I will also add that most battery measurements have been "approximations" in my experience and have found some that are well undersized from the stated measurements.

As to cells draining at different rates, I think you can expect some variation from cell to cell simply due to the nature of the cell. As to why once cell won't charge up, I would be inclined to state the same, but Turbocad hints at some other issue. Turbo: were these home assembled packs? I have used three packs and three boards and not seen the issue. Odd.

The atomizer appears to have big resistance swing from hot to cold or the mod itself has one.

Does it power on when the USB cable is plugged in? The fuse may look good, but has to be tested with a meter to make certain.

So, one cord lets the device charge to 4.28 or greater and another the device stops at your setting (puffs or cycles)? Look at the four resisters near the USB port. The only logical thing that comes to mind is that with a good cable, the "draining" balance function can't keep up with the charge function of the board. The balance charger works by putting a small drain on fully charged cells while it feeds a small charge to that lagging cells are topped off.

You do not want to open the file as it is indeed of a type that has no association. You want to go into escribe and select File and Open to open the file.

What value do you have under "mod resistance". This is likely the issue in that your DNA40 device sees the measured resistance as "all coil" and your 200 device sees it as coil plus mod. Also, the 510 on the 200 device could be introducing resistance variations as it heats, making the DNA200 think that it has gotten hotter than it has (if the 510 is poor, and resistance increased with heat, the chip will think that the coil is at the temperature specified by the total resistance change value, when in fact some of that is not happening in the coil). This is an issue not just for the DNA200, but any TC based product. A poor 510 will cause poor TC performance.

I would try one or two USB recovery charges, but if you suspect shipping damage, it may be best to have it returned to you to inspect.

This is an interesting limitation. So all other functions work as they should? This works as intended in VirtualBox.

Parallels is $79. A windows tablet is the same. I am trying to get a free solution working, but I think VB will have an update soon.

Check the fuse, but even if blown, is should still connect to escribe.

I am with VB...try a manual update from the tools menu, if that fails, then download the older escribe and try the same (it will likely not auto update as the device is now in recovery mode..will require a manual update).

I have not had that happen. Perhaps change the % in ohms lockout range? It appears some of your atomizers change significantly as they heat and cool. I have a few that simply will not work for TC as I can get as much as .08 more on them as they heat and cool.

VapingBad: I finally have an atomizer that I have to use in the mode you cover...the new Aromamizer...nice tank. Not one you want to attempt to adjust with temp settings.
