How do batteries work on DNA20 devices?

[fjgotgame24]

I've been looking around and have noticed people have all types of batteries in the DNA20, some even have 2400mah ones. Since I currently use mechanical mods, I have to use batteries with high amps among other things and don't think there is one with 2400mah. So my question is does the DNA20 not require "special" types of batteries like the mechs? Having a higher mah battery while putting out good power seems like a good deal to me. Then again I don't know how watts work yet...I don't even know how volts work, I just say " Yes it looks nice, I want" Then they say you need this and that and I say " Yes I want"

If there was a wall, I would be hitting my head against it instead of my hand right now!

IF YOU ARE USING A MECH, YOU ABSOLUTELY NEED TO KNOW WHAT VOLTS, WATTS, AMPS AND OHMs ARE; AND HOW THEY INTERACT/RELATE TO EACH OTHER!!!!

You are holding a pipe bomb in your hands and in front of your face. If you make a mistake (known or unknown), you have to potential of blowing your hand/face off.

Baditude and others have a multitude of information you need to read and understand before you continue using your mech. Check out their blogs and make sure you understand what you are using/doing prior to a catastrophic event happening. I'm not trying to preach, but have a genuine concern for a fellow vaporer and do not want to see you on the nightly news as the next propaganda tool for the ANTZ.

My understanding is that the dna20 is not a device but a variable wattage chip and a screen used by modders to create their own vw mods.

If you don't understand the correlation of watts, volts, ohms, and amps, you really should look into it, I believe there's a sticky in the rebuildable forum. If you're using mechs, they have no safety features built in like regulated mods do, and so it's vary important to familiarize yourself with ohms law, there are even free ohms law apps for smartphones.

It really can not be stressed enough. Measure twice, cut once. Always safety first.

I mean I know the rules, like I have 30 amp sonys, MKNE 20a for my batteries. I know if I have less than that there could be some problems, and I build my coils right around .7 ohms but I'm just saying I don't necessarily understand the science to everything. Like voltage drop? Idk...I see people with surgical gloves testing it on a machine. What am I supposed to do if I don't have that machine and want to know? You just listen to what they tell you, right? If it drops .3 cause the guy with machine says so, then that's what is. If you need this battery for this setup then I buy that battery. When I look at battery specifications, it's totally beyond me what it all means except 18650 and the amps. I just know the "rules" to safe vaping. So what im saying is what are the rules for DNA20 devices regarding the battery or are there rules? Like does putting it too 20 watts require you to have higher amp battery.

There is no way to know if your build is at .7 ohms unless you've checked it on an ohm meter, or a multimeter. You also have no way of knowing whether or not you have a short in your build. If you put out too many amps, or run into a short, you could literally be caring around a bomb in your pocket. Catastrophic battery failure is a very real danger for those that use mechanical mods.

To be absolutely clear, I am not trying to scare you into being overly cautious. Understanding ohms law is just the first step to being safe on a mech mod, you also have to know what a short does, what it looks like when checking for shorts, and how to tell if your battery is experiencing one.

There are so many people who approach this potentially life threatening situation with complete disregard for their own safety. Don't be one of them, do your homework, and understand what you're actually doing when you build a coil, why you should build it that way and why amp output, ohms, volts and watts are important.

There is a DNA20 specification sheet available from Evolve here. They say you need IMR or hybrid batteries with at least 7 amp discharge capability. I would consider 10 amps the minimum for a bit of headroom. You can certainly use your 20 and 30 amp batteries from your mechanical mods. They would be very safe in these devices.

I do have an ohm reader...Listen, all I was trying to say was that I'm not sure how watts work in relevance to batteries. I know how ohms work since I follow a chart.

Excellent. It sounded like you didn't, which is frightening. Watts are the end result of volts after they pass through ohms, it's just the end power result that you vape on, so say, you run .7 ohms at 3.7v, that's 19.5 watts. Amp drain is directly correlated to battery life though. mAh is short for milliamp hours, the higher the number, the longer the battery will last on a single charge. The dna20 is a regulated device and will not allow for ultra sub ohm builds, but your batteries would be just fine, if the dna20 mod you want fits 18650s.

So having a 10amp 2400mah battery is definitely safe to use right? That was the whole thing for me is I think its great that you can you use a higher mah battery and still vape with power. Thanks for the response btw, really appreciate it.
Edit: Nvm I got it. How come this chart says 1 ohms the lowest

 

[rurwin]

1 ohm is the lowest resistance atomiser that you can use with the DNA20.

I would suggest going to the website that offers the DNA20 and read up on what the manufacturers specs are for recommended battery application.

However many watts you're putting into your load are coming out of the battery, plus any efficiency losses in the DNA controller itself. So let's look at the worst case:

20 watts, with the battery almost dead at 3.3 volts; 20 / 3.3 = 6 amps.. But the DNA-20 is only 93% efficient, so it's actually pulling around 6.5 amps from the battery when it's putting 20 watts into your load. Now good engineering practice dictates that stuff shouldn't break unless it's overloaded by at least 50%, hence I'd use batteries rated for 10 amps of discharge current or more.

A DNA-20 is considerably safer than a mech because it will never pull more than about 6.5 amps from your battery. Short the output on a mech and it will pull however much current the battery is capable of supplying until it overheats and fails. Short the output on a DNA-20 and it will tell you "I'm sorry Dave, I can't do that!"
