AMDtrucking Posted December 25, 2016 Author Report Share Posted December 25, 2016 According to Evolv's DNA250 datasheet, DNA250 output is limited to 9.3 Volts and 53 Amps.What are these limitations be, If I'm using it with two cell, 167 Watt configuration?Thank you.

Spector NS5 RD Posted December 25, 2016 Report Share Posted December 25, 2016 6.2v 53 amps (obviously you can't push 6.2v and 53 amps at the same time that would be over 318 watts,lol. whichever limit you reach first.) Link to comment Share on other sites More sharing options...

Spector NS5 RD Posted December 25, 2016 Report Share Posted December 25, 2016 AMDTrucking - i made a mistake, it's actually 6.2v (corrected first post). and MERRY CHRISTMAS TO YOU! Link to comment Share on other sites More sharing options...
kbriggs Posted March 5, 2017 Report Share Posted March 5, 2017 ChunkyButt200 said:AMDTrucking - i made a mistake, it's actually 6.2vIs this still accurate information? Because I've seen multiple online stores like VaporDNA here:https://www.vapordna.com/Lost-Vape-Therion-166-DNA-167-Box-Mod-p/lvt167.htmclaim that the 2-cell "DNA 167" can output 1 to 7.4 volts. I specifically just ordered a Therion 166 because I'm tired of bumping into the 6 volt limit of my HCigar VT133. I'm going to be really p.o.'d if I find it has the same voltage limitation. Please confirm. Link to comment Share on other sites More sharing options...
dwcraig1 Posted March 5, 2017 Report Share Posted March 5, 2017 250 in 2 cell configuration voltage output.....6.2 volts max. 1 Link to comment Share on other sites More sharing options...
giz_60 Posted March 5, 2017 Report Share Posted March 5, 2017 Their listing is misleading..also claims 1a USB charging, when the Therion 166 has 2a Link to comment Share on other sites More sharing options...
kbriggs Posted March 5, 2017 Report Share Posted March 5, 2017 Well that sucks. If you google "Therion 166 7.4v" you'll see site after site after site with that bogus number. It's probably all copy and pasted from Lost Vape. I've got some dual clapton builds above 0.5 ohms that I like and I'll hit that stupid 6 volt limitation well before I hit the 133 watt limit. Now I get to hit it way way before the 167 watt limit. Woohoo, what a great design decision there, Evolv. Even my little single battery eVic Mini can go to 9.5 volts.

Why is the completely drained condition of 3.1 volts per cell (x 2) the upper limit instead of at least the nominal condition (3.7 x 2)? Link to comment Share on other sites More sharing options...

Why is the completely drained condition of 3.1 volts per cell (x 2) the upper limit instead of at least the nominal condition (3.7 x 2)?do you own a DNA 200 or 250? it takes a level of understanding electronics to see why it would be buck only when dealing with 11.1v battery voltage but basically you would not need to go above that voltage. You didn't read my post correctly, but that's ok. I said many of the 2S mods are buck only, which is true. I didn't say all of them had a 6.2v limit. Most will will likely state to have a limit of 7.5v BUT that is for a very short time give the cells will quickly call from 8.4v to their nominal combined voltage of 7.4v. Evolv' s boards will give you the wattage you select until the very end cell voltage range, not for just a short time like other boards. 3.1v is the voltage at rest. There will be losses and voltage drop during the conversion, when fire button is pressed, like with any board. Under load the batt voltage could be closer to 2.8 or lower. As an 18650 approaches the 3v mark, voltage drop becomes more pronounced. Like I said, there needs to be a basic understanding of electronics before making statements like yours. Obviously the DNA 133 or 167 is not for you. You would be better off with a 3S version of the DNA 200\250 or series mechanical. Link to comment Share on other sites More sharing options...
kbriggs Posted March 6, 2017 Report Share Posted March 6, 2017 ChunkyButt200 said:do you own a DNA 200 or 250?Yes, I have a pocket-unfriendly Reuleaux DNA 200. Fortunately its 9v output is adequate. And the HCigar VT133 with the 200 chip as I mentioned. And a Lost Vape Therion 166 with the 250 chip in route to me as I write this with the falsely advertised 7.4v output from VaporDNA (and at least a dozen other vendors), which apparently no one else on the planet noticed except for me.Evolv' s boards will give you the wattage you select until the very end cell voltage rangeExcept or course it might not give you the wattage you select at all due to the low voltage output in 2-cell mode. You have to build at or below 0.23 ohms to access the full wattage range in the 167w configuration. Link to comment Share on other sites More sharing options...
retird Posted March 6, 2017 Report Share Posted March 6, 2017 As @ChunkyButt200 mentioned: "The board was designed to be used with in a 3S config, starting with the DNA 200. the only reason we have the 133 and 167 option is because a couple years ago people asked for it here in this forum. people were fully aware of the output voltage limitation when in 2S mode. their workaround........build lower ohm coils."And he mentioned: "Obviously the DNA 133 or 167 is not for you. You would be better off with a 3S version of the DNA 200\250 or series mechanical." I would only add that the 133 and 167 could work for you if you should decide to build a coil that works within the parameters of the device. All my coils work just great within the parameters of my two 200's and three 75's....... I hope you get it sorted out to your liking.... Link to comment Share on other sites More sharing options...

Advertising a wattage increasing without a corresponding voltage increase is a bit of a sham IMO. Link to comment Share on other sites More sharing options...

Advertising a wattage increasing without a corresponding voltage increase is a bit of a sham IMO.It is buyers choice, Evolv publish the specs and anyone wanting 166.66 W would be better advised to to get a 3 cell 250, IMO the 2 cell variants are for people at the lower end of the power scale who still want all the features, and vaping at say 75 W they can get to 0.5 ohm which is not low res by today's standards. Being step-down only brings a lot of advantages and changing that would be a completely different product line from the 200 & 250. My ADV is 0.05 ohm so I love that they built them like this, and ohms have been coming down over the last couple of years so I bet it suits more people than it encumbers.

shugg1967 Posted May 28, 2017 Report Share Posted May 28, 2017 IMO the 166 Therion is awesome it does everything I need it to but Ofcourse I did my research before I pull the trigger on buying it . Plus evolve answered any questions i had about my device .. Link to comment Share on other sites More sharing options...
