2 battery's in parallel

I have 2 entherlands 14.8 volt 4s 3200 mah lipo's ,can i run them in parallel
to make 6400 mah? I wil be useing this in a losi 8t 2.0 truggy,wil i have
enough continuiois amps to run a cool set up ,oh by the way they are both
30c packs and i am useing a mmm with a castle 2200 motor.I think the 2200
runs at 120 amps,will these two battery's be enough? I know i can run one
pack with a high mah, but they can cost some big bucks.What 2 small packs
can i run together that are low in price.Thanks.
