E-revo

[MaxRevo]

I am going to buy a E-Revo when it comes out and I having trouble deciding what motor and battery combination I want to use. Im going to get the Mamaba Monster and I am going to use maxamps cells. From what I understand the E-revo has 2 battery trays that arnt very big so i was thinking of getting either 2 8000mah 7.4v or 2 5000mah 11.1v. The 11.1 would be lighter. I have no idea on how to wire them together and what the amp draw would be with them. I think I have to decided to go with the neu 1515/1Y with the 2 7.4v and either the 1515/2D or 1515/2.5d on the 2 11.1v. I am looking to be able to go over 45mph with a good amount run time and not be 2 heavy. Also any help on how to wire the battery's would be very much appreciated.
