Lipos and charger for me.

Hey guys I am looking for batteries for my Muggy and 8ight-t. I have a mamba 2200 combo for the 8ight-t with a 14t pinion and basically everything else is stock. For the Muggy I haven't started converting yet but I plan on a Medusa 80mm on 6s. Now I need too know what charger I would need for these probably 6000 mah max. I would like a built in balancer as well.
I was looking at these packs:

Oh yeah Basically for the charger I want too stay under 200. I will probably need a power supply as well right? Or can I run it from a car battery lol. Any ways if I need one will you point me towards a PS too.
Thanks guys, I cant wait too get running.
