Imo go with a hi-amp, they come bare so you can choose whatever plug you want to use. I run a 1950/7T hi amp on 4s and it is perfect for racing. If you want a nice controlable setup take the 7T, if you need a bit more speed 6T is the answer.

The maxamps are nice for the money, if you get 8000mah 4s2p i doubt you will have any problems. If you want a higher quality pack the flightpower 4900's are nice, although i dont think they come in single pack formation in 4s.
