Please help! (battery question)

[Deathbox Mnemic]

So I'm just about to place an order for the Cloupor dna 30 box mod (clone), I've heard really good things about it. I'm lost as to what battery I should be buying. It's a regulated devices which will fire down to .3 ohms, I'll likely go no lower than .4 ohms. Since it's a regulated device, does it matter whether or not the battery is protected? I've done some research but I keep getting different answers. I'm ordering it from CanVape, they have lots of Efest batteries which again, I getting mixed reviews on...The mAh isn't super important to me, although the longer battery life the better.

Basically I just need a flat top 18650 battery that I can use without fear of doing something wrong... I'm rather paranoid when it comes to this stuff...Any help would be appreciated!

These will do the trick:

Efest IMR18650 30AMP Chemically Safe Li-ion 3.7V 1600mAh

These are re-wrapped Sony VTC4 cells. The Efest "35A" will also work. It's a re-wrapped LG HE2 20A cell. The DNA30 has a 12A limit so both of these cells have you covered.

You want to use high drain IMR batteries. These are not protected as they are a safer chemistry.

What does the maker of the device say? How many amps will the device require?

I would look at the specs for the device and choose a battery that you feel comfortable will be able to supply the amps required without danger.
