RTA/RDA for DNA200's?

[AllenH]

Hi ECF! Been lurking for a bit here and there, finally decided to start posting. [I need to so I can be a part of the other discussions anyway!!]

My current setup is a DNA40 18650 hammond-A box I built, and I have a Subtank Mini w/RBA and Cigreen Arrows rda.

I'm intrigued and excited about the new advances made in the DNA200 chipset from Evolv, and will eventually be getting one. The only problem(s) is the high wattage output. I assume this is best for RDAs... and honestly I doubt I'd ever make it above 100W- 30 is mostly enough for me right now. But, if I wanted to be capable of getting that hot, I assume I'd have to be careful about the RTA/rda I use!

What do you recommend for the 100W+ regulated boxes? Will a standard rda handle it (assuming the board has protection or you have the right coil built). What about RTA's?

Another issue is of course how well the system is built to handle Temp-control. Steel parts etc., have their own Temp coefficient of resistance... so the fewer the parts between the coil and center-pin, no spring 510 etc., will definitely help temp control. [One reason that the refinement was such an issue was due to this problem.]

I'm all ears! Thanks for your thoughts!

Something like a mutation with some massive 22g coils should handle it. Or a goblin/goliath tank.

As far as the mod handling it. You just have to pray whoever builds one actually gave some thought to the parts used.

 

[AllenH]

Ok, excellent. Yeah, I was thinking of the Mutation myself... I've been eyeing the v4 for a bit here.

I also know from another reputable source that the older Kayfuns are excellent for TC- but I have no idea how hard they are to find, or if they can handle higher wattage.

I'll have to check out the Goblins and Goliath's... haven't paid attention to them... was eyeing the Lemo2. But, seeing the Lemo1 inside, I wasn't sure they'd handle the TC very well. [Although now that I think about it, my subtank mini has a similar pin setup as well, I believe. - if we're talking just purely the current path, not handling the wattage of course.]

I've been toying with trying out a non-spring loaded 510 to see if that helps TC on my dna40 build.

Thanks a ton for the reply, Thrasher! I really appreciate it!!

 

[AllenH]

Oh- just thought of something else, Thrasher- when you say massive coils - I'm a bit surprised by 22g... I'm using 28g and with a 13 wrap coil or so I can get close to 0.2 ohm... I assume the same at 22g would be way lower resistance- I always assumed I'd need to be up higher rather than lower in resistance... any thoughts on this? It's all different with regulated mods of course... there's a low-ohm setting. On the DNA200 datasheet, this happens a bit under 0.05 in Ni wire temp reg mode (if you have it set at 200w I believe). That's quite low, so maybe it's not that important...

 

[Thrasher]

When you get into that kind of heavy wattage its not so much just about resistance, if your really wanting to push the limits of the mod smaller gauge coils will get too hot way too fast. And my thinking is a large number of wraps may hold a lot of heat after letting go of the button. Cooking the wick

It doesnt need to be huge as in a lot of wraps, but more of a heavy wire that will handle the high power a bit easier without turning cherry red in 0.25 seconds

22g is just a guesstimate looking at things like the mutation just starting to work well in the 60+watt range.

Any kayfun should work well fot tc, as well as orchid, rose, or any of the other bottom feed tanks. I dont see why you couldnt use tc in any of them

 

[AllenH]

Hi Thrasher! Thanks for the insights there! I appreciate it. I'm fairly new to vaping, have a bit of electrical background, and work in materials science... so I know just enough to be dangerous. lol

Your comments make a lot of sense now, thanks! Yes, having it go crazy hot right away might be an issue! And likely why I've seen mini fires with people using their normal setups on the dna200 betas.

Ah- in regards to the kayfuns, I believe it had to do with the setup internally- what types of metal used, and how they were touching each other etc. [The source was highly reputable- so I listened, but should have asked more questions when I had him on the phone.]

Good to know about bottom-feeder tanks though. Thank you for the names of others to check out. I appreciate your thoughts and time with this! I'm not sure when I'll be getting the DNA200 in, but hopefully it will be in the near future. If so, I'll be back to share my experiences.

A big thanks to you for the kind welcome and great insights, Thrasher! I appreciate it!!

 

[Thrasher]

Let us know how it goes, and what you finally end up with

 

[AllenH]

Gotta ask one more thing here... I could make a new thread, but don't want to innundate the board. It's great to find ECF so responsive and large... the ECR subreddit is nice, but there's a ton more info and more indepth work here on ECF. So glad I posted!

Question: I mostly do mouth only (come from pipes and cigars) - so I've found I need less airflow than most- as I don't cloud-chase, but go for flavor in mouth only (and cycle breathe through nose- if that's a term)...

So... which RDA would be good for flavor over airflow? [asking here due to the DNA200 implication]

Thanks, Thrasher, and will come back and let you know how things go!!

Every RDA should work with it if you build low enough. For an RTA, the goblin or the goliath will work also, but I don't recommended it. Also, the Herakles tank should work if you're looking for some high wattage subohm tanks. The maximum wattage I did on the herakles was 70-80 W, I did get spitback from it. Well, I was just comfortable enough by using 25-40 W devices.

 

[AllenH]

Hmm- good to know, PsiangLaut. Do you just not recommend RTA's for that high a wattage at all, or just those two specifically? Glad to know about the RDA's... then the cigreen I have could work until I get a new one. It's a bit of a weird build, but has been working for me lately on the DNA40.

Thanks a ton for weighing in here! I appreciate it!!

 

[PisangLaut]

I don't recommend any RTA to be used in a very high wattage, the goblin and the goliath will work if you run it on 40-50W with 24g 0.3 ohm dual coils, I never go lower than that on those RTA's, but I think the juice won't feed the cotton quickly as the herakles and you will burnt your cotton/rayon inside (for me, having a burnt cotton/rayon inside the RTA's is pain in the a** no matter how easy I disassemble the deck). Except, you found the wicking method that can feed the cotton very quickly. Maybe you can prove me wrong by inventing some new wicking method

 

[AllenH]

Hi PisangLaut! Ah yes- the feeding problem. I completely understand. I have issues even at low wattage with the old rba subtank mini. You're right!

 

[Thrasher]

I know its off topic but if i scan real quick i think the title says ......ed lol


I ran into the goliath rda today, holy crap what a monstrosity, heres your 200 watt dripper. The deck looks intense

[AllenH]

Hey Thrasher! Yikes- that thing is massive! LOL on the ......ed! Thanks for all the input! Man, an authentic is over $100 for that... yikes. I'll have to do some digging/learning on the RDA side before I pull the trigger.

 

[Thrasher]

So get a clone for 10 bucks just to play with.

And make sure ya have an oxygen bottle handy

 

[Plutoker]

I think I'll stick with the Velocity and see how she handles the heat. Really love the grub screws, deck and airflow options. Not sure which tank I'd throw on it yet. Thoughts?

 

[Kaezziel]

If you want a RTA that can handle higher wattage, you might check out the Silver Play V2. I have one that I have ran to around 100W on a mech with no dry hits... it has plenty of airflow, and is easy to lung-hit with. I've not tried the Goblin or any of the others mentioned, but I can definitely attest to the Silver Play. Well worth the cost of admission for me...

 

[AllenH]

Thought I'd update the thread a bit since a few posts happened today. I received by mail yesterday a Goliath v2 RTA, and I have to say I'm very glad I bought it. No leaks at all, juice control ring which I can stop down to nothing, and huge airflow (for those that like it- I like a draw). However, my vape is quite hot at even 50W right now- I have it on dual coil option at the moment. With the juice control open, it handles VG and no dry hits at all (however, I'm using temp control- it never kicked in even at nearly 100W when I first vaped on it- much too hot, so I turned it down). Now I'll have to find a nice RDA to complement my non-leaky tank.

I will say that on the Goliath the flavor is not as good as my RDA - but I was expecting that. And the build deck is tiny tiny... I'll never be able to make vertical coils I suspect. (again this is for the RTA by UD, not RDA mentioned above) Even if I can't hit the higher watts here, or get perfect RDA flavor, just having a nice non-leaking tank is going to rock. Thanks everyone for weighing in here! Cheers! [will continue to subscribe to the thread for any other suggestions!] ps- Silverplay looks excellent also!

 

[Kaezziel]

Glad that you're liking the Goliath, Allen... I've been a pretty hardcore RDA guy, myself. Then I bought an Orchid V2 a while back and loved it... till I cracked the plastic tank. I bought the Silver Play V2 so that I could have a working tank again, and I do not regret it one bit... it is a great little tank, and goes through juice pretty quick. As for RDAs, I love the Hobo and the Derringer for flavor (but you'll want to keep the wattage kinda low, cause they'll get hot if you're not careful), and the Mutation X is great for cloud chuckin'... just keep playing around and you'll find what you like and what you don't like... best thing for me is FastTech... buy cheap clones and decide if you like it... then get the authentic if it turns out that you like it.

 

[AllenH]

Thanks for the thoughts, Kaezziel! I appreciate them! I guess I'm learning with each new tank that things are a bit diffferent. I honestly wasn't expecting a hot vape with this Goliath v2... shows me what standard wattage can do. I suspect I'm missing something big still and need more time and experience building to get things really right. But, I'm enjoying this Goliath - I think it's the best tank I have right now... (major props for no leaks, I must admit)... now I just need to find a TCR stable RDA that can take dual vertical coils nicely. [I'll try some of your suggestions!] I will admit to having a desire to buy on fast-tech, but wanting a safe way to purchase without fear of credit card problems etc. [had those with earlier vape orders, at least I think so.. and others have mentioned the same- not necessarily about fast-tech]

Thanks again for all the warm welcomes and the great discussions!!
