If you select update firmware from the menu, it will let you browse for a file. I think there are multiple linked to posts in the firmware section. I am on my phone right now, but if not I will get some alternatives posted tomorrow.

Easy to install older, download it in the software and firmware section of this forum and then go to tools, update firmware.

Edited my last response. Is the extra 10 percent run time at cost of 3-4x less cell life really a tradeoff you would knowingly make? Also, you might start charging into the overvoltage protection diode, which would be less than ideal. But I will do more digging Monday.

You can charge any lipo to 4.35v , it just does terrible things to cell life. We don't think it is a good compromise, but we will consider it. Basically it takes a typical pack from 300ish charge cycles to about 100. You get about 10% more capacity. So what the "high v" batteries really are is high cell life batteries they are encouraging the user to push really, really hard. If you take the same battery and only charge it to a standard 4.2 you end up with something more like 1000+ cycles.

If the atomizer analyzer is showing a question mark, it doesn't think that the atomizer is connected. Can you screenshot a graph of power, temperature, cold ohms and live ohms as you fire and post that here?

I'd you revert to an older firmware with the same coil, does the problem go away? If you use atomizer analyzer and wiggle the connection and/ or the coils, does it stay stable? If so, at what resistance when the coils are completely cold?

That's the reference case. We made it, the design is available here on the forum. We'll probably make some runs of cases once we get into the full swing of things. I imagine somebody will be in the business of putting them together, so I'd expect you'll be able to get one eventually.

Really what you end up doing is dropping the max resistance for 200W from .40 to .36 ohms. Or about .20 to .18 temperature controlled. And only when the battery gets near dead. That's the only downside.

Definitely not normal. If you are handy with solder wick and can remove it, you're welcome to do so. If not, send it back and we'll fix it. Sorry about that! I'll add a check for bridges there to the AOI program.

You may well be our first tester on the windows 10 preview. I guess we will have to get another test machine.

My best guess from what I see is one of the three vias on board edge got soldered to the adjacent B+ pad due to the unusual edge-in soldering. They would have been directly below the b+ lead. Those three are part of the charger circuitry, so it would have worked fine until a charger was plugged in, then poof. I suspect if we get a picture of the front side of the board we will see damage to the charging electronics. But we are happy to replace the board, especially now while we look for bugs and collect information on potential trouble spots to warn against.

Is this case metal or plastic? It looks like plastic, but that damage sure looks like the input battery lead shorting to a grounded case. I haven't seen an input pad burned away that severely without other damage on the board from other things. The negative battery lead soldered on at a right angle and almost touching the USB has me a bit concerned. Do you have a "before" picture? In any case, even if this turns out to be some sort of assembly error, send it back to us and we will send you a new one if it is dead. Pre-release I would like to analyze any board failures, regardless of cause. Thanks!

The max output voltage becomes 8.5V when using LiFe. The outputs, charge voltages and cutoff voltages adjust appropriately when set to LiFe mode. So no, other than not having quite the top end for high power high resistance coils, there's no performance hit.

70 F should be 1.00 Normalize to that and you should be good.

Looks okay to me Lollerwaffles. Nothing wrong with building a tapped pack out of 18650s if you do it well. Besides, you're using Kapton. If you wanted to cause concern, what you want is masking tape holding bare wires to the ends of each cell.

The CSVs and the internal calculations are and always have been 16 bits below the decimal point. We reduce the display to one decimal point in Escribe for readability. Right click on any point and type in the exact value. Also, the numbers are not ohms, they are normalized resistivity.

Yeah ours is 11mm tall including the center pin. It is wider, uses an expensive spring and takes a costlier CNC machine to make than the FDV design, but is higher performance. Hopefully someone will take the reference files and start banging them out in quantity at some point.

They're USB shield and run through an R/C filter to ground, but they're primarily mechanical.

Connectors are supported and recommended. I like XT30. It isn't that early, we've had outside testers since April, and the private beta has been going on since mid-May, so don't be afraid to ask questions. Anything we don't know yet is something we really ought find out.

Our reference connector is a good 3mm shorter than a fat daddy V3 if I'm doing my numbers right. We don't have a ton of them, but there are some left over from the beta. You could hit up Brandon and see if he will sell you one.

Oh no, that one is fine. It is just LiFePo4 instead of LiPo. Just select that chemistry from the dropdown in Escribe and it'll act appropriately.

USB chargers don't leave the data lines floating, there is very specific signalling. DCD is the mode prevalent standard for USB chargers.

Protovapor was saying that they have some.

I think he is using device monitor, so it sees the device as active.

You shouldn't brick your device, and even if you did, we'd replace it. I'll turn you over to James who wrote Escribe and see if you guys can replicate it.
