LiPo batteries and chargers question

Hello

I'm going to make an hexapod robot and I need a LiPo battery. The 20 servos (SG-5010), when moving, needs 12 A.

I've already bought some servos in the past from Hobby king, and now I was wondering if you can suggest me a LiPo which works with my configuration: http://www.hobbyking.com/hobbyking/store/uh_listCategoriesAndProducts.asp?idCategory=86&v=&sortlist=P

I want to buy from Europe to avoid custom duties. Also I'll need a charger. http://www.hobbyking.com/hobbyking/store/__216__408__-Battery_Chargers.html

What do you think? Thanks for your support.

Best wishes
