Neu 1515 2D (2050kv... which is rpm per volt) or 1Y (2200kv).

Castle Monster Max (no brainer IMO... absolutely the easiest and best if it's as advertised)

I would go with two 6s 4000-5000mah packs and wire them in parallel to get 9000-10,000 mah. With that much battery, I think you don't HAVE to have the best battery money can buy, and there are plenty to choose from. The Neu packs and Enerland based packs (polyquest, flightpower etc) are popular... or the Maxamps 5000s will be fine too IMO. (Not as bad as some here claim)

Charger: I suggest you get a power supply so you can pick from any charger and not just the very few that are AC/DC. Even a cheap computer power supply can work.
