I'm wanting to buy some battery packs from [link]http://www.cheapbatterypacks.com[/link] and I was wondering if anyone could help me decide on which battery to pick.

I want to build a 7 cell 370aMH for my Pico Stick and was wondering if the Gold Peak 400 or CBP350 is a good choice. Also the website says to use 22 gauge wire with JST plugs but will 18 or 20 work?

Thanks!
