DNA 200 Watt

[vapealone]

Though 2 x 18650 battery DNA200 draw 50% more current that normal for a given wattage so use better batteries like VTCs, HE2s, 25Rs and not the 3000 mAh brown ones.

Agree, but it is still 23A max that even the HG2 can handle especially that vaping is more like pulsed discharge than continuous.
However, the batts' IR and the voltage drop it results an other issue.
For the dna uses V under load only to cut off high wattage vapers might get better battery capacity and/or safer discharge out of a lower IR batt like the VTC5

So I think it is how you vape on it.

For me, the 2x HG2 will do. It is only the mod now that I need to build around it

Why would the dual 18650 draw 30 amps instead of 20 amps. they can't have the batteries draw more than 23 amps because the onboard fuse would blow at 25 amps.

the chip will always pull 23 amps MAX dual or triple. hardware wise it is impossible for the board to pull more than 23 since it would make the fuse blow.

and the LG HG2s are perfectly fine. they are officially rated at 20 amps. most studies have proven that they are true 20 amps continuous. with 35 amp pulse apparently. getting a VTC4 over a LG HG2 or 25R is just useless since you are giving up so much capacity for a amp limit the board will never reach. hell the VTC5 is technically also only 20 amps(VTC4 and VTC3 are 30 amps).

The best batteries you can buy right now for this mod are HG2s.

No still 23 A max, just say for 100 W with 97% efficiency from 11.1 V you need 9.28 A and at 7.4 V you need 13.92 A.

But they don't like it LG INR18650-HG2 20A 3000mAh Bench Test Results and you are not getting 3000 mAh, only a problem at the top end, but worth pointing out to folks.

Just a small vape store in belgium. they have alot of NICE stuff like all dem fancy philipines mods and ..... out of nowhere they were all "oh hey we got the reuleaux in".

I loooove this thing so far. haven't tried temp control though.

running a mismatched(2 green one blue) samsung 25rs since I haven't gotten around ordering 6 LG HG2s yet. but since the DNA 200 monitors every battery separately you don't have to worry about killing a battery from it depleting faster. at most you lose some battery capacity.



You don't need 30 amps 18650s. 20amp 18650s are just fine. I mean the chip only pulls out 23 amps max. these batteries can handle that easily.

I wasn't saying what I would do. I was just stating what evolv said when they released the board and firmware updates. They say 30 amp obviously to cover themselves. Not saying I wouldn't run the lg's. I run them in everything they last forever.

Well, it is a constant current discharge, but yes, better be safe than sorry so I wouldn't use this batts if my ADV required 20+A discharge, pulsed or constant
And yes, I dont get near the 33.3 Wh nominal for 3x HG2s when tested at 50W but the 28.4 I got is more than enough for me.
And yes for the third time, higher load discharge would result even lower Wh especially if you play it safe

Safety aside if your are maxing the DNA200 with 2 x18650s you will need 30 A as they generally have more V sag than LiPos, at lower wattages they are fine.

And still better than the 25r. if you look at his reviews of the 25r it seems like the battery comes out to about 2100mah for 25 amps while the HG2 comes out to about 2500mah for 25 amp.

20 amps it seems like the 25r hits about 2300ish mah. the HG2 comes at 2675mah.

So the LG HG2 is still better than a samsung 25r. the only thing that compares to the HG2 is the 30Q so imho is either of those fine.

 

[VapingBad]

The 3000 mAh irreversibly degrade when used at over 20 A where 25Rs, HE2s and especially VTC don't. As I said they are fine if you are not pushing it, but just saying.

Good point, but they both lost about the same percentage and AFAIK 25Rs are cheaper. Not bought 18650 for a few months (have 20 25Rs & 10 VTC4s), but believe there is no such thing a a free lunch. Meaning that there is always a trade off between sustainable current and capacity.

Lets also not forget.

This is him doing continuous testing. We don't vape our batteries empty at 25 amps constantly. we pulse. I highly doubt that pulsing 25 amps will do as much damage as him firing the battery at 25 for the entire charge. Our batteries get a chance to cool down more and we know that heat is what kills batteries fast.

Absolutely, but it gives you a way of comparing them, also remember as they age they will fall below this performance so the more head room the longer they will last all other thing being equal. IMO ability to supply current (same as voltage sag in practical terms) is the key attribute after safty.

So today I tested out the differences between older batteries and newer batteries.

I only really have 25rs and I was only really able to mix two relatively new samsung 25rs(green) and one of my older blue 25rs.

I know that it can't hurt the batteries since the DNA 200 board keeps a eye on every single battery.

technically triple 25rs should come out to about 27wh. after the battery capacity test. 22wh.

turns out the older blue 25r was at 3,16 volts while the new greens were both at 3,45 volts.

man. you can really see what age and recharges does to a battery.

I'll bring that # 3 cell up, battery is not the problem. This is the second one to drain down to 3.85 while not being used and not charge any higher while the other two charge to 4.20 volts.
I get it back up.

Umm, just might have two bad Lipo's, it appears it doesn't want to go above 3.86 volts. more time needed to be sure.
Nay, it's coming up, hooray. Now if I can just keep it up (hey I'm an old man)

Almost got it, it should correct it's self from here..... or go south again but I'm hopeful that it's going to be good.
I liked it better when I thought the battery was bad, but not two in a row.

And later:

My guess is that juice was between pin 2 & 3 under the plastic balance connector plug on the board making it drain down. I cleaned it with "something"

I like all things hana including my v200. I would like even better reuleaux if it is 3x 18650? I have to use sxmm or kanthal while hana is charging. the guy lied to me thinking I might not buy it I guess. he said it charges the lipo in 40 minutes. yeah, sure. still prefer when I am on the dna200 now.i actually backed the watts way off to 55. it needs to be at 500f. that is fine. it is just that I guess the yihi chips are way off. I am certainly getting a better vape on this now. I could probably do even better in escribe but I am afraid to get a mouth full of burnt cotton. I am sure there are nicer ones but the hana is a good little box imo. I like that if I need service I often get to the west suburbs.

 

[dwcraig1]

I just went and got my original Vapecige battery back from my friend. He tried to balance it with his RC charger but it wouldn't do it. He did balance it though using the same method that I used. Might be time to build a mod but Evolv doesn't have any DNA200's (screens) right now.

 

[nic_fix]

theres an idea. I can get more batteries and use rc charger. not only does it have terminals they are far more advanced than pila etc. you guys probably know this already though. strange it would not balance it. my cells are all the same but I can throw it into runaway. don't know why but hana said it is not broken. just do not completely discharge it. I wonder though this is taking like 6 hours to charge. I think my battery is indeed suspect. ride to hana is in order I guess than.

Does the DNA have dry hit/ no liquid protection? I was doing a build today and I tested the coil on my DNA 200 lips boxer mod. With no wick it fired until it hit the TC limit then stopped.

I moved the atty to my SX Mini M & immediately the no liquid message displayed upon firing.

Does the DNA 200 not have this feature or do I have to go into escribe to set it up??

That's basically what temperature protection does for you. If it makes you feel better, you can change the message "Temperature Protected" to "No Liquid".

Hana will say and do anything not to do anything for you after you spend $210. I had to send my v200 to Evolv to fix a bad ground issue. Turnaround time was 6 days.

Not looking to 'feel better', they function differently. The DNA 200 still heats the wick (or no wick in this case) to the set temperature even if there is no liquid. The yihi doesn't even fire if it detects no liquid or wick, but will heat to the set temp when liquid is detected.

Just looking to see if I was missing something in the settings.
