Test complete. Mine came in at 9.949 Wh at 50W and a 3.09v specified cutoff voltage. The .csv file is attached (remove .txt extension from filename). Lavabox_DNA_200_3S_11.1v_9.949_Wh_Battery.csv.txt

I'm running the test now on my Lavabox DNA 200 and will post the .CSV as soon as it's finished. Running it at 50W into a ghetto 0.9 ohm resistor consisting of 4 long-ish (and ugly) loops of 24-gauge kanthal wire.

There is nothing mysterious or complicated about measuring the mod resistance. Just short the 510 with something like a brass or copper pin and read the result in the atomizer analyzer. Done. Really don't think you need laboratory conditions for that. And, if in doubt, there is absolutely nothing wrong with leaving it at zero. This will simply cause the chip to err on the conservative side of the temp control loop. On the other hand, it would be unwise to plug in a number that is too high, as it will then err on the "wrong" side. James and/or John posted on this a while ago, but I can't find the post at the moment. If I recall correctly, they recommended taking something like a 20% haircut on your measured result, just to be on the safe side.

I measured the internal resistance of my Lavabox simply by shorting the 510 with a copper pin. It measured .007 ohms, which is significantly lower than the .02 they are telling you.

That makes sense. I'm going to run the test myself this weekend when I get a chance. Still curious whether it periodically unloads the cells to measure resting voltage throughout the test and uses those resting voltages to generate the discharge curve. It almost has to be that way.

Thanks for the clarification. Should it give me the "new coil? (y/n)" prompt, assuming the cold resistance of the new coil differs by an amount that exceeds the ohm lock range that I have set in eScribe? I haven't been getting that prompt, so I've been assuming it was continuing with the most recent reading from the previous atty. I assumed the reason I wasn't getting the prompt is that I had not changed my ohm lock range from the default of 25% (even though most of my atty's differ by an amount less than that).

I'm interested in this as well, but so far I haven't stumbled across a higher capacity pack that will fit in the space. Hopefully someone will chime in with a suggestion.

Excellent info. Thanks for the link and suggestion. My TC builds tend to settle in somewhere in the .10-.12 range, and I have probably 6 or so atty's in the rotation at any given time in that range. Like you, I would prefer it to ask me *every* time I attach one. I've had a few too many of the--as you said--"warm" hits lol. I'm going to drop my lock range to something quite low, maybe 1% even, and see how that works for a while.

How are you guys dealing with this scenario? Setup separate profile for each atty? I haven't set up separate profiles yet, and what I'm finding is that if I put on a new atty with a similar (but not the same) resistance as the previous atty, it won't recognize it as a new coil. I guess I could change my ohm lock range to something other than the default 25%, but I'd rather not have to do that. I guess if I let the new atty sit on the device idle for a few minutes, the chip will eventually adjust the cold resistance downward (since I tend to not lock my ohms), but that doesn't help for the first few minutes after the new atty is attached and I want to start vaping it right away.

I haven't had a chance to run the analyzer yet, but I'm curious about when the analyzer terminates the test. Does it simply cut the test at a preset voltage (as measured under the load of the test)? If so, what is that voltage? If it's using voltage under load to terminate the test, I presume it would be best to run the test with a load that is representative of your typical atty. EDIT: Also, are the SOC curves based on voltage at rest or voltage under load? I presume it's the latter, since the data would be gathered by the battery analyzer while the cells were under load (unless it periodically unloads the cells, allows them to recover, and samples their resting voltage). If that's the case, I'm also curious about how the battery meter works (since the resting voltage of the battery will be higher than its voltage under load). Is the battery meter basing its estimate of SOC on the voltage of the battery when it was last under load (i.e., during the last puff), or is it basing it on the resting voltage at that moment? If it's the latter, then it seems to me that it would always be overestimating SOC (assuming the analyzer doesn't periodically sample resting voltage throughout the test).

Dual spaced coil w/ 26-gauge Titanium (Spider Silk) 7.5 wraps each around an M3.5 bolt Settled in at 0.23 ohms Installed in a Vector RDA Wicked with organic cotton Sitting on top of Lavabox DNA 200 Dialed in at 450F at 40.0W I'm floored at the experience so far. This vape is simply at a whole new level. Best flavor I've experienced so far, after many many kanthal/nichrome builds on both regulated and unregulated mods. Definitely not the prettiest coil you'll ever see, but man she really vapes incredibly well .
