Recommended battery and charger for M4

[ExTERmINATION]

I'm looking for a new battery and a new charger for my M4, I don't know much about batteries and a good charger so I thought I stick up a thread to find some help here.

A little info about the gun right now is that the connection for a battery is at the back of the stock. It is a TM based M4, it was customed and solid on ASC to myself. The owner of the gun said it was recommended for a 9.6v for a game.

So if anyone could help me out here that be great! any links, websites to some batteries and chargers would help me out big time, like I said I'm not fimilar with batteries and chargers.

I have always been more than satisfied with the chargers and batteries that I have gotten from bb bastard, http://www.bbbastard.com/ although they may not have exactly what you want.
