Don't base anything off of the batteries. Base everything off of the motor that you are running. In your case, you could get away with a controller rated at about 60amps continuous with the Feigao 380C 13t.

You shouldn't need to cool the batteries. In fact, it could be more harmful than helpful. The inner cells of a Lipo will get the hottest, so if you are cooling the coolest cells, then that means that the inner ones will suffer the greatest, causing them to fail earlier.
If a setup is capable of making the batteries hot enough that they need to be cooled, then the batteries aren't capable of handling that setup.
