This problem was caused by operator error, by not exiting the menu mode. When this is done the chip will not go to "sleep" and will drain the battery. The next software upgrade will address this and not let it happen.
hum.... blame on user error? I'm thinking the chipset designer didn't test to see if this could occur or they would have mentioned it in their specifications so the user would be aware or would have already corrected it prior to release...at any rate I'm glad they are fixing it with software update.....
You're right. The chip itself should have a "timeout" feature where it reverts to default if the user doesn't properly exit the menu options. But as far as glitches go I've seen much worse and this one is easy to avoid.
Still waiting for that explanation or a video of the dna firing on fresh battery at 3.5v or below. Put your money where your mouth is....A lot of talk on this forum and clearly bias views. Where do I go for a factual adult conversation?
question for other Evolve owners. I have a VS rDNA 30. I hadn't run any of my RDA atty's on it yet.. so I thought I would play. Put my tobh on it, has a dual coil, coming in at .80 ohms. what would be ideal watts for that? or is it just play, see what fires, and find what works for me?
or others that may run RDA's on their evolves.. should I build for a higher ohm level? is there value i that? just learning what I can do with this rDNA
thanks

I am not bashing the thread, I am just getting tired of people posting crazy findings or "truths" and not backing it up. I encountered the same person stating the DNA can regulate under 4v on fresh battery. He won't ever answer me to show me proof, so I figured this thread should be the BEST place to put this to rest once and for all.
Retird, do you have any proof or knowledge that the DNA can regulate under the stated 4v, and do it on purpose or intended?
Thanks for your help. And if I am wrong I am BEGGING someone to prove me wrong. I just am seeing a lot of new vapers being given wrong info, and that is a darn shame!!

0.8 should be fine, especially for dual coils. With singles, I prefer 1.0 or a bit higher. Of course, much depends on the build itself, i.e. the geometry of the coil(s), how well your build wicks, airflow, etc.
I don't do RBA's or sub-ohm.....those that do have been discussion the regulation below 4 volts... you might try PM'ing the poster you want info from...or he may pop in and respond... and what experience have you seen with your Evolv DNA as far as regulation?
Do us a favor: Spend $16 on an in-line volt meter. Screw it onto your DNA mod. Screw a reasonable load (say 1.0 ohms) onto the in-line meter. Set your DNA to 7.0 watts. Fire it and look at the voltage the meter shows. I've done this with a fresh VTC5. DNA claimed it was firing at 3.8. Meter read 3.65. Oh, and that was a DNA-30. A DNA-20 will go a bit lower.
well.. regarding the regulating down.. I have a dual coil build, .\reading .80 ohms on the reader and on the DNA 30.
@17 watts.. it running 3.7
@16 watts, the ohmmeter is blinking, and it still shows 3.7, suggesting to me, it fires, but at 3.7 i.e. it doesn't report to down regulate..
edit ^^ Rossum's suggestion would be more accurate

What is the output voltage at the battery under load and what is the voltage reading at the inline voltage meter while firing?
retird, I don't have a inline meter, thats why I edited to suggest rossum's post =)
my post was info displayed from the Evolve only..
use of inline meters would be most accurate method

Gottcha.... just thought you might of measured with meters...
This may or may not be what your looking for but follow the link and there's power measurements comparing an Evolv DNA 30 and a clone DNA 30. One file is the spreadsheet comparison with 5 different tabs for .75Ω, 1Ω, 1.5Ω, 2Ω & 2.7Ω resistances and the second file is the signal traces from a cheap oscilloscope I've come by recently. If you look at the first tab .75Ω you'll see that it's RMS values from 7 watt through 15 watt on the Evolv board is persistently 3.43-3.44 volts. Now these tests were done with Sony VTC5 fully charged batteries a couple months old measuring 4.17-4.18 volts when installed. I don't know I'd consider this any type of regulation though as I believe it's just the battery dump minus some loss in the circuitry. If you look at the signal traces they are all very flat DC whereas once you get to the regulated side "over 20 watts @.75Ω" you'll see a bit more switching and a little noisier DC signal. Now the clone on the other hand does appear to be doing some type of regulation albeit not correctly. Hoping to find and electronic guru to explain the clone signals below the supposed 4 volt range.

That is one of the better charts I've ever seen, great work. A little disappointed you didn't go a little more granular on the watt settings but then again you had no reason to since you were not specifically looking for where the evolv chip started regulating. What you are seeing from the clone at low settings is not regulation at all, I believe.
To answer the question in your notes, the reason the DNA didn't hit 30w at 2.7 ohms is you reached the chip's upper voltage limit. Which, it should be noticed, is also different from what the specsheet says.

Thanks, it was pretty time consuming. What would you attribute the 2.x volt square wave to on the clone in the supposed "unregulated" power range? And yes I updated the notes tab tonight after thinking about it a bit it dawned on me the 8.3 volt spec limit.

Looks like a 65% duty cycle to me...
That trace came out to 1.99v RMS and with the spike on the leading edge 65% would be pretty close. Also if you look at the next couple traces that are in the "unregulated" range as the watts are increased so is the duty cycle.
