Are meat thermometers accurate enough? I have one that I could possibly 'borrow' for the night if it is

I don't know. If you put it in contact with the part that heats up it might.

I believe that it would be the herb chamber/bowl, I know it (the thermometer) measures below zero and reaches up to 450°...im thinking that should be sufficient and I 'borrowed' it anyways, so hell...its worth a shot

@WakeAndVape If you can find one of these it would work well. just point and it tells you the temp.

Edit: if anyone in So-cal has an Ascent I'll let you use my thermometer for some "testing purposes", that is if i get to do some "testing in with the Ascent too

I am curious, how do you know this will work well? Please educated us because I am with OF on this one..

I have a craftsman one that i use and have had good experiences with, thats all. I actually hadn't even read OF's post when i posted tat last post.

I use a fluke 179 true rms multimeter with a fluke thermocouple that has been striped and sterilized placed into the center of the bud, but careful not to touch screen. Fluke claims accuracy at +/- 1%

Maybe a fluke is up to the task!!![:\](/i/s/hmm.gif "Hmm :\")

It is not so much the brand, but the type of thermometer.. I have a Fluke IR but it is not good for this application.

Thanks for clearing that up, I was insinuating so maybe someone could cue in!!!lol It worked lol
Thanks @toros23
What type of thermometer would be best for this type of measurement? I would like to measure not only the bowl temperature by direct contact, but also the contents of the bowl at different positions. This, for me, would help to correlate actual heat output to known vaporization thresholds of herbs and such. That's the explorer in me.

Yeah that's what my 'deleted' comment was about. I was thinking that measuring the bowl temp wont be accurate if your looking for a specific effect from a particular temp. What's more important is how hot the herb gets.

The only reliable way to read the bowl temperature is probably spot weld a thermocouple on. Contrary to popular opinion, it does not have to be an actual 'couple' physically, You can, for instance, weld a fine Platinum wire on one spot, and the mating Platinum/Rhodium wire at another location. This will read 'an average' of the two spot temperatures, but usually works just fine.
Thermocouples are also probably the way to go sensing load temperature, but have heat sink issues. They'll read low because the metal is drawing heat away up the leads. Very fine wires are called for (sometimes only a few thousandths thick) which are of course frail.
Thermistors are also an option for load reading, but they too have the heat sink issue, and the equipment need to use them is trivial (any DMM will do it).
It's a pity Pyrometers don't seem to work well. I once used a custom one with fiber optic snout that might read bowl temperature in use but it was mighty pricey. It did fix focus and field of view issues though. There's also an "Emissivity" issue in play, different materials 'shine different' when hot. Common Pyrmeters use a compromise value, some of which are adjustable.
Not an easy job, or we'd have the janitor do it.

You're welcome, of course. No problem with individuals not knowing all the answers of course, we got teamwork goin' here.......
I also agree. Since 'DV's numbers fit' what we expect based on other vapes, they gain value to us. Empirical Evidence is still evidence. I put stock in ABV color, texture and remaining THC content. IMO it's a valid way to rate vape performance.....and number free.

If you can not replace the batteries in the Ascent yourself, and have to send the item back to get the batteries changed, how long before this will need to be done and how much will it cost?
As with all Lithium Ion batteries, they do go crap pretty quickly and not being able to change them, this is going to add a considerable ongoing price of the vape.
DV only offer a 90 day warranty on the batteries
"The Lithium Ion batteries however are subject to degradation and reduced run time over the course of regular use thus carries a warranty of 90 days after purchase to perform as designed for forty (40) continuous minutes at 200 degrees F."
As seeing as the Ascent is designed to vape best at higher temperatures the 40 continuous minutes is more like gonna be 20 minutes.
Just trying to figure out how long it may last before purchasing.

Wow! Let's hope that's a typo and they meant 200C? It's Canadian, right? So 'metric' is their native language? If it's right we're in some trouble time wise. Doubling the temperature doesn't cut the time in half, it's closer to 1/4 in most cases. That means it'll (maybe) make it through a session at 390F? Naw, can't be.....guys testing them would have noticed that and mentioned it you'd think?
In general Li-ion cells like we use are good for 3 to 600 cycles, give or take. Subject to a lot of things like heat, current demand, depth of discharge, charge control and so on. This means you should probably expect something like one year (worst case cycle life, charged every day) to maybe 4 or more years (charged carefully, protected from deep discharges, kept cool and so on and charged 3 or 4 times a week).
The key to long battery life is, I think, keeping the battery cool, not discharging too far and stopping the charge when it's still 10 or 15% from full (this alone doubles cycle life in some cases).
For 'back of the envelope' planning I'd say an average 450 cycles might be a good number? Where's Haywood when I really need him? He's a guy who knows this good stuff cold.

Great point UKoldman. I would be interested in knowing that too. And while we are at it, how much would it cost for getting the batteries replaced beyond the 90 day warranty. I doubt anyone would have a definite info on this. What has the experience been for folks who may have replaced batteries on their Davinci vape?

Does this hold true to all the batteries we use? I know a vape I have the PN I have to fully charge because it has very few sessions. I did notice already it is down to 6 when I used to get 7. We do need haywood on this. Haywood where are you
? It amazes me how we all get different info. I know I just got a new cell phone and they told me for longer use and not a huge dip after 50% discharged do just about full discharge before recharging that topping off makes that dip happen. I did notice on my old cell when I got to around 40% it dipped to almost dead in no time and I was unable to use it. I wish we can get one answer from all people. I have heard so many version at this point. I am sure it also depends on the product but I could be wrong.

I went through a few sites to come up with these best practices:
1) "Fully charge new lithium-ion batteries for the first three cycles
New Li-ion batteries will work best if fully charged, and drained, for the first three charging cycles after purchase. So, after each charge, use the device until the battery completely runs out of juice, says Isidor Buchmann, author of Batteries in a Portable World (Cadex Electronics)."
2) "Once past the first three cycles, the rules change. Charge the battery periodically, for short periods. Don’t wait until it needs a full charge. "
3) "Avoid exposure to extreme temperatures
Hot car interiors and Li-ion batteries don’t mix. While a fire is unlikely, leaving electronics containing Li-ion batteries, such as your iPod or cell phone, in a hot car can result in an untimely death to your battery. “Leave your iPod in a hot car, and that will kill it. In places like Florida, it can get up to 130 degrees in a car,” Zarr says. “Extreme heat degrades Lithium-ion batteries.”
Extreme cold is also not good for Li-ion batteries. Don’t try to charge them in freezing temperatures, advises Buchmann, whose company produces battery chargers and battery analysis software. Trying to do so could cause permanent damage to the battery."
4) "- More abusive sessions of use will be more damaging to the battery's prolonged usability; keep this in mind when gaming intensively on mobile batteries or otherwise rapidly depleting them." Gaming = vaping here

If your post is correct @novicevape then that answers why we get conflicting answers cause both answers are correct in a way.
Thanks NV and VN.
Edit: So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent as OF said in the other article.
It is so funny that they can't really just say what to do ugh. But this seems like the best answer between the sources that we have gotten.
1. Three full cycles
2. Discharge to around 40 and charge to 80
Of course that leaves us the big issue of vape time being diminished.
So since this is the ascent thread...reviewers have said on a FULL battery about 1 1/2 hours now we have to take away about 25% of that time leaving us with just over an hour. If this vape really goes that long. On most vapes it will give us about 1/2 hour of vaping which is not enough.

I remember someone saying that the Ascent will use Panasonic 18650 batteries. These are the go to for 18650 for e-cig vaporizers and they really hold themselves up well to time.
It might not be hot swappable but if they are these batteries it shouldn't be too hard to solder some new ones in yourself (assuming you have worked a soldering iron before).
