Yea bet it would not last long at all...I plan to use a 18650. As far as this debate here it really does not matter to me what other people use in there mods, so long as we are safe ya know.

You can get 12 amps out of a battery that isn't rated for 12 amps using the DNA30. The only time it protects you is when when then the battery voltage under load falls below the threshold. That doesn't make it a good thing to do. I got a ton of atties built with juice in them, all different specs. I'm going to go with a battery that will support the amps that the device provides. Recommending otherwise is just dumb. You don't know what another person will be using.
yeah, there is a fine line between battery safety and battery paranoia. suggesting that a 10 amp continuous/18 amp pulse capacity battery is going to blow up with a dna30 is based more on paranoia than reality I think. I'm all for safety but not so much into paranoia.
I just want to clarify something here: The amperage drawn from the battery is INDEPENDENT of the coils resistance. 20 watts is 20 watts regardless of resistance, and due to the fixed voltage of the power source, you have to calculate amperage using ~3.7v.
I believe the DNA 30 is 93% efficient (someone correct me if im wrong)..
So Input Current = Output Power / Input Voltage...
eg: lets say you set the device to 30 watts...
given 93% efficiency, you have to calculate amperage using ~32.3 watts (30 / 0.93 = 32.258)
So amperage drawn from the battery is equal to output power setting (32.3 watts, given efficiency losses) / input voltage (~3.7v)
amperage from battery = 32.3 / 3.7 = ~8.7
So the higher the battery voltage, the lower the amp draw and vice versa... so if your battery is down to 2.5 volts (just an example, the DNA board wont fire at this point) your amperage from the battery will be 12.92 (at 30 watts.
So EVERYTIME you set the dna30 to 30 watts, you are drawing 8.7 amps from the battery (given a 3.7v battery), regardless of the coils resistance. This is approximate, since a batteries voltage varies under load (and between manufacturers, due to varying internal resistance of battery)
I hope this clears a few things up.
Cheers!

Ha! Nobody mentioned blowing up, nice of you to interject that for the first time!. It's about the right battery for the job. Another peaker reads a few posts and just gets it! Nicely done and thanks for your well researched and comprehensive input.
yeah, wasn't no one but wasn't you bill who suggested that my face would be in danger but it seems there's always someone who is going to go there
and I also said that I think it's more of a perfect match than grossly under spec.

My first response was for the post 2 above mine.
You probably understood the amps volts watt equation better the I. When all is said and done, I will go with the manufacturers statements for battery requirement and it is 12 amps continuous. I wonder why that is?

overcompensation and extra buffer maybe?, kind of like mcdonalds huge red WARNING, COFFEE IS HOT!.
in the end it is impossible for a dna30 to ever draw 12 amps continuous regardless of what the manufacturer says and maximum draw above 10 amps is going to be dependant on duty cycle and pulse duration

That's the thing I don't think you get. A "12 amp battery" is not always the right battery. Because AGAIN, not every set up requires 12 amps. Kind of like how the DNA30 can do 30 watts, that doesn't mean you have to use 30 watts, or it can carry a .5 ohm load, that doesn't mean you have to put a .5 ohm load on it.
Another thing you refuse to acknowledge, this thread is a thread for a device that is designed to use 18350's, and 18490/50's, so what about the Futura? Are you saying it is dangerous or not up to the task with those batteries?
Is the ZNA not up to the task with an 18490? Even though Evolv designed a board for it specifically?
Shut up taptalk
It can cover a wide range of tasks sure. But I'll still go with the mfr recommendations because unlike you, they actually know what they are doing. I mean they invented the darn thing and not just for Zen specifically. What have you done? What is your expertise? Why should I take your advice over the designers?
I'm not saying you are right or wrong. I just want you to admit that the Futura and the ZNA are poorly designed.
That is what you are implying.
Shut up taptalk
Lol, you completely refuse to respond to facts, instead hanging to your bigoted paranoia instead to the bitter end.
You still refuse to answer the question, seeing as you have implied this, whether or not the Futura is dangerous as designed. You seem to think so, am I wrong?
No, no, no, the guy who goes into a vendor thread, implies that certain batteries will be dangerous in the device made by that vendor, including batteries it was obviously designed to work with, calls me a troll?
Way to loose to the internet.
Shut up taptalk
Fortunately the DNA boards have short circuit protection, so it's pretty unlikely you're gonna blow yourself up, regardless of battery type. Makes for very safe RBA construction too. As for the DNA 30, our order is supposed to go into production this week. I'll keep you all apprised of the status as it Evolvs. Ok, back to the flame war

I know, lol, I don't think he gets that though lol.
I'll stop cluttering up the thread now, I've said my piece.
Shut up taptalk
They told me two weeks about a week and a half ago, so not much longer, I pray...
one of the things that makes a regulated device superior in the safety department is that you don't have to worry so much about overloading the battery or shorting out a coil, the electronics protect you, the worse thing a bad choice is going to give is poor or no performance, not result in portable pipe bombs.
all that battery venting and exploding crap is pretty much reserved for the mech heads out there
