DNA 200 Watt

[Pdizzle]

I've been told from a guy who says has 100 boards in the mail right now that evolv will be selling for 100usd on their website yet protovapor has pre order at 80usd
What's the right info?

The discussion of how bad you can make things with a small coil and 200 watts seems to miss the point that it is designed for pushing the atomizer tech and builds a bit. If you over power your atomizer you get crap. My builds start to suck at 35 watts but are great at 20. Would I fire them at 200 and think "wow this device sucks" or put another way would I turn stoopid just because I bought a new mod? I have been theorizing with folks off list as to how you could build for this new power and there are options that may give great a great vape.

There are hundreds of examples where we have more power than we need, and manage the power intellectually. Do you fry eggs on high, drive you car with the accelerator pressed to the floor, run your AC at max, play your television as loud as it will go etc? No, we all know power modulation and have to practice it every day. Saying that it is a downside to have more power than you currently have a method of utilizing makes no sense.

Absolutely. Pick a modern supercar that's capable of exceeding 200 mph (there are several of them). It's no problem at all to drive such a car in traffic on your daily commute. But it strikes me as rather pointless to do so, and there IS a downside to it: The cost of maintenance and wear items. Check the price a set of tires for a Veyron (if you can even find them anywhere). What are the wear items in a mod? The batteries. Every mod maker is going to end up using something different in DNA200 mods. Sure, you can use three 18650s, but that will yield an ungainly large mod.

Now I don't mean to sound negative, and I think I understand some of the reasons why Evolv made this board. I'll buy a couple of boards to play with the tech, but I don't see myself vaping at 100 watts (much less 200). What I'm looking forward to is for the tech (which is primarily software) to trickle down to another, smaller board that can run on a single cell again. 50 watts is still double what I actually NEED.

Maybe it was marked up so they can make a profit and the 80 is what they actually go for or they just lowered the price for the pre-sale and will go up when the pre-sale is over.

Still not bad for a 200 watt temp sensing board.

That is a completely reasonable post...not knocking the tech just because the tech isn't for you

Looked at Phil's internal shots of the Opus 200 on tasteyourjuice.com.

Taste Your Juice | NEW IN THE QUEUE – THE OPUS 200 – 6/17/15

From the photos, I'm not keen on the LiPo protection. The reason I say this is that the 510 positive pin is right up against the end of the LiPo pack. On my Turnigy batteries, that's just a plastic white film on the end. It also doesn't look the battery is secured in any way to prevent travel in that direction, except maybe sticky tape. So if this mod were dropped hard onto the 510 end, that pin looks like it could travel right into the LiPo pack.

Then again, maybe there's something not shown in the photos (e.g., a hard plastic separator built into the cover to prevent the above scenario), but without knowing for sure I'd look at other DNA 200 products before buying this one.

Isn't that 1000mah battery only capable of 25A continuous (1000mah = 1A; 1A * 25C = 25A)? Granted it's 50C burst so it's probably fine, but I can't find how long they are measuring burst (probably 10 seconds).

Well offered me one for 105cad and I'm not sure if I should just wait

25A * 10V (about as low as you'd let a 3S LIPO pack get) = 250W. I don't see the problem here.

You stole my car analogy that I had all ready to go!

And you're spot on with the trickle-down effect, but I hope it's more of a gully washer! I really want to see a new board with the smaller "foot-print" of the 40, and of course, I want it NOW!

You still wouldn't be able to use it in the vaporflask.

 

[Pdizzle]

Not a great comparison but I'm powering my sx350j with a 1200mah 7.4v 2s lipo and I need to charge it everyday and I only vape at 35w. Don't use temp control

A less powerful board with some of the new tech

Understand what ya are saying.... I wonder if that is even possible since the balancing charger feature requires board real estate as does the balancing connector required for the battery pack....

 

[Cotay]

25A * 10V (about as low as you'd let a 3S LIPO pack get) = 250W. I don't see the problem here.

Maybe I'm missing something, but the DNA200 is capable of 50A continuous output. Shouldn't the LiPo be at least capable of that?

I'm hoping for a 60-80watt board that's 2x18650 compatible and user up-date-able...

A fella can wish, right? (my Flask was too expensive to go in my "Prehistoric Mod Museum" already)

The DNA200 is a DC to DC power converter

The DNA200 is a DC to DC power converter

Right. Watts Out = Watts In * Converter Efficiency.

Converter efficiency here is almost certainly higher than 90%, probably close to 95%.

As a machinst you of all people know it's possible. Just massage the chip and lipo in there.

Gotcha...thanks!
