Need some Help!!

[Furymongerr]

So im working on my first DNA20 device and im looking for my power source. Im looking at www .batteryspace.com/highpowerpolymerli-ioncell37v1900mah603495-20c703wh40adrainrate.aspx will this work with the DNA20d and the evolv charging chip?


Thanks,
Jay

Yes it will work but you may want to consider the turnigy 2200mah instead. Turnigy 2200mAh 1S 20C Lipoly (Single Cell) (USA Warehouse)

Alright Thanks! Now will i need to put a Pcb on the cell or does the dna 20 have it built in? I will also be using the DNA20 charging board.

the dna20 cuts off at low voltage (3.2v). the charging board cuts off at 4.2v.

Ok that makes it really easy then. Thanks for your answers! Looks like i can just use the cell sans the pcb and save myself some time.

Why do you recommend this battery? Does it meet Evolv's specs? 2200 mah is a decent chunk of life. That battery looks like the one I'd like to go with too...

Yes and I also emailed Evolv on it. They said it was a great choice as well. And that it was fine without any sort of protection board, But will work with one if you wanted to use it.

I recommended it to the OP because it's basically the same battery with more life and for less than half the price. But in general these types of LiPos are great for ecig use as long as you are willing to accept the safety factor.

That battery would handle vaping better than any round cell in existence. There are 2 problems you have to deal with though:
1) the tabs are aluminum. You need special flux and solder to make connections to those. regular lead solder and rosin flux will not work.
2) the battery physical size is huge: 97 x 34 x 8mm

As noted, that battery is referenced because it is similar to the one the OP posted. From what I am reading the tabs are nickel plated(?) and can be soldered with regular solder and flux.

All of the single cells I bought from HK had a small piece of solderable material crimped to the Aluminum tabs. This crimp is kinda flaky and easily damaged when you manipulate the tabs. I recommend you have aluminum solder standing by... Chances are you're gonna need it.
