You can charge it by just plugging it in, you don't NEED an external charger. You could always start out without one and get one later if you wanted. Once I had to experiences the lil crappy screws on my chana, I understood why people always complain about them. I'm not going to keep unscrewing those.
Now your mileage may vary, and I know everyone is going to say "get a Sony" first, but Sony batteries are harder to find these days. For a regulated mod, mAh is more important that Amps, sorta kinda. I know Evolv recommends a battery that can sustain 12 amps as a minimum for the DNA30, so that's a fair rule of thumb. I went with an Efest 3100 mAh, 20amp battery

I've been happy with mine, haven't even drained it yet. Only downside to a big mAh rating is it takes longer to fully charge.
From a review of it I found somewhere, it may be a little shaky at the 20 amp level on a mech mod, but it should do 12 amps easily.
I see MBV has the 2500 mAh version for sale, if it's any easier for you to just have one package, could always just go for that. A little less capacity and plenty of amps.
