What mod do you have? And how many batteries does it run on?

Yes you can connect it to the PC with or without batteries. Although you won't be able to fire it without batteries, but everything else will work. You don't need to create a profile. But profiles are handy for making a bunch of changes at once. And you must be using Stainless steel coils in your Crown. eh? So what are you running it in, temperature control or wattage mode? The Reuleaux DNA200 (both my two) were setup for Ni200 for all profiles. Running SS coils in TC that is setup for Ni200 TC would be horrible. As it would either be too hot or too cold and nothing in between. You can adjust the temperature to the highest 600ºF and then click once more and it will report OFF. That means temperature control is off. Now it should vape fine on wattage.

Those readings are with one of my multimeters. I do check them with EScribe too and EScribe is the same or one insignificant digit higher.

The DX200 v1 the lipo was crap. While the DX200 v2 is using a FullyMax FB900HP-3S 11.1v 900mah lipo.

FullyMax Pack 1 of 3 (red) Charged with DNA200 USB 1A 2.5 hours finished charging (Max Recharges 4.10v per cell) Before charging unloaded Cell 1 = 3.30v Cell 2 = 3.28v Cell 3 = 3.12v Pack = 9.68v After charging unloaded Cell 1 = 4.10v Cell 2 = 4.10v Cell 3 = 4.10v Pack = 12.3v It is very clear this FullyMax Pack 1 of 2 after repeated discharging and recharging has a lower capacity cell 3 than the other two cells.

For a new lipo pack giving you those readings would be very unusual. If you have a multimeter, we will tell you where to take readings. I would disconnect the lipo pack. As if it is the DNA200 board like I think it is, it will just drain cell 3 and ruin the pack.

No, I don't think your board is good. Every one I heard of the same thing happening, it has always been the board. You could try software reset, hardware reset, and force firmware update and stuff. But it doesn't look very hopeful.

Yes you can. You don't have to worry even connecting something that can't provide 1A either. As it will only draw as much as it can safely draw, up to 1A. Anything more, it won't use. The only thing you have to worry about is that your USB source isn't putting out something high like 5.5v or more.

While the DNA200 doesn't have reverse polarity protection. But if you did reverse the polarity, it is suppose to blow just the fuse on the board and save everything else. Also the HCigar VT133 added reverse polarity protection that the batteries must pass through before getting to the DNA200 board. Although I haven't tested any of my four yet to see if the reverse polarity protection really works.

So with just the balance connector connected, how does the DNA act? Does it read the pack voltage too? Does it fire? I won't fire with any amount of watts, just something low like 1 watt. I don't know how many watts you can safely draw off of the balance connector.I didn't try to fire it with only the balance connector on but as I posted earlier pack voltage was there but the cell voltages while adding up to the pack were unbalanced. Checked with a meter though they were balanced. I'll try again when I actually get up.

Oh yes, well the only 3S lipos I have are the DX200 ones.

No I didn't disconnect the USB. If you did, it disconnects from EScribe. And the DX200 you really can't just disconnect the balance connector alone very well without making a test cable or disassembly.

My Hotcig DX200 v2 shows the following when I unplug my lipo. Pack: 2.91v Cell 1: 0.01v Cell 2: 1.35v Cell 3: 1.56v With a low lipo it reads: Pack: 11.23v Cell 1: 3.75v Cell 2: 3.75v Cell 3: 3.74v

And to add to dwcraig1's suggestion, unplug it from the USB when you disconnect the battery. As with the USB plugged in, it still gets power and removing the batteries for a bit will not reset the DNA200.

Yes that would be a good guess.

Oh CB... you mean you don't trust reverse polarity protection on battery chargers?

Titanium and stainless will change resistance due to temperature fluctuations. If you are checking with EScribe's Atomizer Analyzer, it warms the wire up a bit.

I never replaced a DNA200 fuse yet, but I mostly use a desoldering pump (aka solder sucker) to remove solder and the component (you need to clean inside of them a lot). Never cared much for soldering wick which wicks solder up into the braid of flat wire. I'll use it if I have too. But my favorite for removing solder is a vacuum desoldering station. Oh I wouldn't buy one of those cheap soldering irons with a rubber ball that is suppose to vacuum up solder. Those just gets you frustrated more than anything else.

FullyMax Pack 2 (red) Charged at 11.1v @ 1A 63 minutes finished charging, reported capacity is 903mah. Cell 1 = 4.17v Cell 2 = 4.19v Cell 3 = 4.17v Pack = 12.52v

What is your mod resistance set at? Ever run the Case Analyzer on it?

That low cell 3 bothered me so I charged it individually to v3.47v, discharged it some. And it settled to 3.44v. Waited 30 minutes and it stayed right there. FullyMax Pack 1 Charged at 11.1v @ 2.5A 10 minutes to build up to 2.5A 23 minutes started dropping from 2.5A 30 minutes finished charging, reported capacity is 912mah. Cell 1 = 4.20v Cell 2 = 4.20v Cell 3 = 4.21v Pack = 12.61v

Cell 1 = 3.41v Cell 2 = 3.40v Cell 3 = 3.31v Pack = 10.12v

Yes that is correct. Since I had the cell cutoff at 3.05v, I had to stop since I couldn't vape anymore. It is just sitting right now. Cell 1 = 3.36v Cell 2 = 3.35v Cell 3 = 3.23v Pack = 9.94v That is reading it unloaded at the balance connector on the battery. But as it sits it has been creeping up a bit. I'll check it again in the morning.

Here is a manual I wrote that might also help you out. This shows you what you can do without EScribe.
