The Blade CP Pro should include the charger and battery out of the box. Also, the included charger is supposed to have a built in balancer, though I've never seen it tested how well it works. If you wanted to move up to a nicer charger, I would recommend the FMA Direct CellPro 4S, but you shouldn't need anything out of the box; it's all in there.

Good Luck!
