Battery safety

[Raymond Nicchia]

Hi, this is my 1st post on this forum so hello everyone! I am very confused about what would be the best battery to use in my Dna mods? I have tried to look for the answers but just don't understand what I find and can never find a straight answer! Now what I am confused about is current actually needed for any mod! From what I see, if a mod requires say 50 amps, how do you achieve that with a dual 18650 for example? I am using mostly LGHG2 20amp, 3000 mah and Samsung 30q's! I also use some 25r's, he4 and he2 and have been told they are not the right batteries to be using! Starting with the hg2 and 30q being virtually equal performance batteries and rated as the best batteries for vaping by Mooch and just about anywhere else I look, what formula am I not understanding to know they are safe batteries to use in a Boxer dna 167 or lavabox dna 200 or a few 75w dna mods I have! I just don't comprehend it as hard as I have tried and not for a lack of research but for the fact that for some reason I just don't understand it which is odd for me but this is something I just can't grasp!! I'm hoping some of you knowledgeable people can explain in a way I can understand and also if my batteries are good enough for the applications? At this point I feel like I need to go out and purchase 40-50 new batteries but am almost sure I don't because again, my batteries are some of the highest rated batteries! PLEASE HELP AS IT IS DRIVING ME INSANE!!! Thanks so much in advance and greetings to you all!

i'm don't know a dna... but the HG2's and 30Q are good enough for more setups... mod makers they like to produce mods that go higher than the batteries can, i own a dual battery alien 220... it's never going to go that high with only 2 batteries.

The manufacturer of the mod always recommends an amp rating for the battery to be used. While you are unsure of these issues follow that exactly. To be extra careful use a major brand like sony or LG and buy from a supplier who knows how to avoid fakes. To be even more careful learn how to use Watts law so you can evaluate a particular battery for the maximum power setting you plan to use.

Yes I've p

 

[Raymond Nicchia]

Yes, I've purchased all my batteries from Liion wholesale so trust the authenticity! As far as manufacturer operating, I quess what I don't understand is if you have a mod requiring 50-60 amps, if I use two or 3 20amp batteries, is the battery amps doubled or tripled to reach the required amps or am I just using 20amps for a 50amp mod?

 

[Raymond Nicchia]

Furthermore I'll give you another example that may or may not be related! I just got a Vape droid 75dna and paired it with an OBS rta with a 0.14 build! I can vape at 60-70 watts until the battery drops below 68% and then it won't reach the wattage unless I drop it off course! I tried with a big baby beast and pre-made coil of 0.15 with almost the same results! Are the ohms just not compatible and will have to stick with my more powerful dna or any other more powerful mods for that matter! And the dna 75 is using a 26650 if that makes a difference

Watts (power) = Amps•volts.

As the voltage is depleted by vaping, the current will increase to maintain the Wattage as demanded by the user.

This is a reciprocal relationship. Divide wattage by volts to compute current. Don't exceed CDR as rated on a legit cell..

 

[Topwater Elvis]

The evolve DNA chips will never draw 50 - 60 amps from the batteries.
DNA 200 23a max battery drain / input current.
DNA 75 28A max continuous 32a pulse / input current.
Straight from evolve spec sheets.

Resistance is irrelevant when calculating battery amp demand using a regulated power device.

 

[mongo74]

There isn't a single mod that I'm aware of (other than mechanical) that can draw 50a.

I'm vaping with a set of HE2's right now at 80w without issue, and have been for the last couple days. They're great 20a batteries. If you're using them in a regulated mod, as long as you do not go above their CDR (current discharge rate) and they aren't re-wrap clones, you're just fine.

To find the best battery for your regulated device, divide the wattage+10% for device inefficiency by mod cut-off voltage (we'll say approx. 3.2v for single battery) to get the current you require (and battery cdr to vape safely.) If it's a dual battery mod 6.4v and triple 9.6v (as long as they are series and not parallel devices)

Half my problem is that I don't understand what specs I should be looking at!! You say 28amps dna 75 input current! Is that the current it needs (input current)? And also at 28, my 20amp battery wouldn't be enough then??? And in my other question I refer to using a dna 75 with an OBS rta with a 0.14 that will allow me to vape at the desired wattage of about 70w until the battery reaches about 65%! Then it won't reach the wattage! Is it just asking for too much power for the pairing of the two? Do I need to just stick with lower wattage tanks /coils and use a tank like that on a more powerful mods???

Again I was just throwing out 50w! Definitely not rewraps, purchased from Liion wholesale and lghg2 should be able to outperform he4 in every aspect so why is this guy telling me I might be better off with his batteries of course or even he4's or he2's with a dual 18650 dna 167! Even his batteries he claims are 25amp 2600 mah but have been tested by Mooch to be I believe 10amp batteries

Input = from batteries to chip.
Output = from chip to atty/delivery device.
Have you properly set up your DNA devices using escribe?
Especially the wh battery settings.

The DNA 167 is a " de tuned " DNA 250 with 28a max input.

In multiple battery regulated power devices the batteries share the input load.

Seems you're stuck on the ultra low resistance thing, no reason unless you're using temp control & suitable wire types.


The vtc5a 18650 is a 25aCDR 2500 mah cell.
Choices in 26650 are very limited, the Ijoy 4200mah is a 30a CDr cell.

Who? No HG2 are not the best batteries, they have the best capacity but they can only do 20 amps and they heat up around 25 amps. Just use a name brand battery and you'll be fine. Evolv boards monitor the batteries constantly so you'll be fine.

 

[KenD]

As a general rule, 20-amp batteries (for example LG hg2, he2, he4, Samsung 30q, 25r, Sony vtc5, vtc6) are good up to 60w per battery, 25-amp batteries (Sony vtc5a) up to 75w per battery, 30-amp batteries up to 90w per battery. That's for regulated batteries, whether parallel or series.

Thanks so much for all the help everyone! With all the responses, I definitely have a better understanding now, I ended up buying A bunch of VTC5A'S for a few specific mods to be on the safer side and continue to use hg2 and 30q's in the rest of my mods! I don't vape anywhere near 200 anyway! The only time I come close to max is on the 75w with certain tanks or builds but using the higher wattage devices for those now! I liked the rule of thumb explanation as it is a simple way to remember what I should be using! For example if I am understanding correctly, I would be much better off and just fine with a 25amp battery for a 75w mod than a 20amp but no need to use a 30amp and only 1500mah! And why is there no battery input settings for a dna75 on evolve like a 200 or 250? And because there isn't any, how does it know if I'm using a 26650 to take advantage of the extra mah on the ijoy 26650 batteries I'm using?

Resistance is unimportant on a regulated mod. Calculate based on upper wattage selection what the amp draw is when the batteries are discharged, then choose a battery/s that matches or exceeds this amp requirement. Batteries with a high amp limit will have a low mAh, batteries with a low amp limit will have a higher mAh. Pulse ratings should be mostly ignored unless you know the risks, CDR is king.

[Darth Omerta]

Definitely give all the articles listed a good read! Guys like @Mooch, @Baditude and @sonicbomb explain things in very direct and simple ways!

Basically for my use in regulated multi cell mods I like to use 3.2V as the cutoff even though I never run my batteries beyond 3.5V so here is (what I feel to be) the easiest way to look at it...

If you are using 2 cells at 100W, then essentially each cell is producing 50W
The cutoff(when you should charge your batteries) for each cell is 3.2V so we divide 50W/3.2V=15.625A
Factor in the inefficiency of the mod(usually around 5% but I like to highball it with 10%) so divide the amperage by .9(90% efficiency) and we get an approximation of the mod(chip) drawing 17.3A from each battery.

If your battery is rated at 20A then you are safe even at the lowest charges you're likely to be using.

This is merely my simplest explaination of calculating amp draw for muti cell regulated mods. If Ive said anything incorrect then please let me know!

Im also hoping that you are aware of marrying your cells for multi cell regulated mods. You mentioned a few different types and I just want to make sure you're not mixing and matching your cells in the devices that need 2 or more cells. Using a married set in multiple mods is fine, swapping out one of the batteries for another and separating the set is a nono!
