DNA 200 Watt

Systems Engineering?

Think of it this way.
Rolls Royce, GE or Pratt and Whitney can make the best engine possible....
but if they don't have a great airframe partner their product is not going to fly.

I think it wouldn't be beyond reasonable to think of advanced vaping systems in the same way.

I have zero worries with today's lipo tech. Seems many here are stuck in 2010.

Agreed and glad we heading that direction.

 

[alicewonderland]

the main concern is i live in california. It gets hot outside and in my car, you can say just dont leave it in your car but im not looking for a mod that i cant bring places or just vape at home. the LiPo in that vaporshark really is a killer for me. Also the whole replaceable battery thing, I've already owned one LiPo DNA30 mod, and i hated that I couldnt just swap batteries in when the old one discharged, this is why I have been mainly using my vaporshark rDNA40 over my old dna30 mod, the lipo DNA30 is basically retired due to not being able to just swap n go, and not having peace of mind being able to leave it in my car at the college campus.

x a million.

Get over it. Just make sure you have good home owner's insurance if you're using Lipo's.

Are lipos really that fragile? I knew that puncturing them is bad but some people sound like looking at them makes them explode.

LiPos are safe if properly packaged into a device. Lots of stuff uses LiPos safely, such as phones, tablets, and computers. They key consideration is whether you should bring unprotected high-capacity LiPos into your home. To that, I would say only if you are willing to exercise a very high level of care. I've used unprotected high-capacity LiPos for RC stuff, and as Tony points out, you really need to be careful with unprotected LiPos. I keep my unprotected LiPos in fireproof bags or containers, even when charging. They are definitely not something I would just throw in my pocket should I need a spare battery for a mod. Also, it's just not punctures that can cause problems - dropping an unprotected high-capacity LiPo on the floor can easily ruin it and is dangerous.

This is nothing about the DNA200 using LiPos per se, but rather how the mod makers will package it. For sake of safety, I wouldn't buy a device that doesn't use swappable protected LiPos.

Yozhik re: your statement
"For sake of safety, I wouldn't buy a device that doesn't use swappable protected LiPos"

I agree with you Yozhik but I'd edit and change one word to your statement for my situation.

Mine would go

For sake of sanity, I wouldn't buy a device that doesn't use swappable protected LiPos
The sanity would be my own.

Exactly.

I have a theory why suddently Evolv presented this board with 200w and all these bells and whistles and specially why the use of 3S lipos but it's not the time.

So essentially replaceable lipo batteries are a disaster waiting to happen. especially if people get to do it that don't know anything.

hell now I am scared of making my own box mod. wiring and chips and .... isn't my issues. 18650 batteries are fine but lipo. never even held one of those things.

 

[tchavei]

I wouldn't say disaster... As long as you know what you're doing and respect them.

I don't know, maybe we are overreacting. I remember when I returned to vaping last year and the first thing I did was post how weak the 18350 and 18650 in comparison to my lipos and everyone jumped on me that safety was priority and all that. I respect that but now suddently the power hunger has stepped over and lipos are being introduced in this industry.

All I can say is: if we have to use lipos then the dna 200 seems to be safer than most. What other chip do we know that has a balancer circuit onboard and real time monitoring of all 3 cells?

It surely will detect a lot of potential mishaps but it can't prevent human stupidity.

I can't believe the amount of fools in this thread right now. Fools that believe LiPos are evil and can't be used in a safe and effective manner. Guys like @tchavei that is spreading rumors about RC heli guys charging cells beyond 4.2v. Sorry, being an RC heli guy for more than 20 years, and dealing with LiPos in RC helis for the last 10 I know you are full of crap. There isn't a single mainstream charger out there for LiPos for RC heli use that doesn't cut off at 4.2v/cell and as long as a balance charge is used monitor each cell individually keeping the charge voltage between cells at less than .2v. Even a cheap 39.95 charger will do that. If your "friend" charged above 4.2v on any cell he had some homebrew charger that he cobbled together in his garage and didn't have a purpose made charger for RC use. I believe Evolv does have a purpose made charger for LiPo use, and will not present the issues your "friend's" homebrew charger does.

The LiPo argument is just BS in it's entirety since we have years of data on mods like the MVP that have been using them successfully in the real vapers world without serious issue. I haven't heard this argument leveled against the MVP line, but all of the sudden it's an issue for Evolv? Please, think about it for a minute or two. The Evolv DNA200 has a balance charger on board to specifically prevent the issues many are saying will occur. It just won't. LiPo charging is not in it's infancy and the tried and true CC/CV method of charging with balancing between cells is robust, safe and has been used for many years in many different industries and hobby uses. And it has proven to be not the unsafe fire hazard that some here are purporting it to be. It is a mature tech that been proven over time.

I do understand that many people are ignorant of how LiPo charging works and all the safety measures good charging algorithms and monitoring entail. And I would encourage those folks to at least google how this is done before making uninformed speculation on the dangers of LiPo technology. I can tell you that if it is as many have unintelligently presented here really existed, it would not be a mainstream tech for phones, notebooks, RC hobbies, and yes, vape products. Please speak from an informed perspective before coming to an erroneous conclusion.

Just a few more facts about the software (beta):

There is a “Mod” area:

Battery
Type (select battery chemistry being used)
LiPo
LifePO4
Power Supply ( PSU 12v. and don’t use with batteries)
Capacity (mah) (usually shown on packaging)
Cell Soft Cutoff (dna will attempt to control the power to prevent any cell voltages to go below)

Electrical
Mod Resistance (resistance of the mod)
Ohm Lock Range % (maximum % difference in resistance that will be assumed to be the same coil)
Preheat Time Limit (maximum amount of time to preheat the coil)

Thermal
Case Analyzer (used to analyze your case’s thermal properties)
5 temperature/heating/cooling setting components

There is a “Theme” area: (Custom Screens)
Contains default screen messages
Screen messages can be customized

There is a “Screen” area:

Display (adjustments)
Orientation (left/right)
Battery Meter (screens on which to show battery meter)
Error Flashes (number of times to throw a control message.. such as “weak battery)

Fields
Default Fields 1,2 and 3 (left side of display top, middle, and bottom) shows default or what you select
Charging Fields 1,2, and 3 (left side of display top, middle, and bottom) shows default or what you
select while charging.

Brightness (adjustments and duration)
Firing Brightness (brightness when dna is being fired)
Active Brightness (brightness when dna has been recently fired or adjusted)
Idle Brightness (brightness when dna has not been fired for awhile)
Charging Brightness (brightness when dna is charging and not being used)

So do LiPo batteries not go up in flames if they do fail?

Ive seen some pic posts and PSA's (cuz of summer) on ECR of melted mods of people who left their mods in their cars. Isn't that still a thing?

 

[KTMRider]

Just stop. Please.

 

[druckle]

Isn't being able to replace your battery conveniently a thing?

 

[Jazzman]

So do LiPo batteries not go up in flames if they do fail?

Please list the MVP failures you must be referencing.

 

[Vooper]

Please list the MVP failures you must be referencing.

No, I'm referring to the tech as a whole.

Do they not actually go up in flames if they fail?

 

[alicewonderland]

does the dna200 have to be used with a lipo? i mean the snowwolf is a 200w TC device that uses 2x18650s. I personally wouldnt mind a chunkier vaporshark that used 2x18650s rather than have a LiPo in there, and im sure others would think the same. People who are going to be buying 200W box mods dont really put form factor and portability at the top of their lists.

not exactly sure what mod or battery this was though. but it was on ecr as a summer PSA of a dude who left his mod in his car, and from the gist of what I have so far, lipo batteries are unsafer than li-ion batteries. Maybe im dumb oh well, but that's my choice of not wanting to purchase any more LiPo mods, moreso mainly because I want to be able to change batteries on the fly and dont want to mess with new chargers/LiPo batteries myself.

 

[Mooch]

No, I'm referring to the tech as a whole.

Only if the temperatures are high enough to ignite the solvent. And that takes thermal runaway, occuring at over 225°C.

Below that the cell can vent, just like other chemistries.
