Northy is correct. When I raced at Newbury (indoor with jumps) I could do 3 x 5min runs with a 5500mah Maxamps saddle pack in my B44 and a 6.5 Novak motor.
Lipo's have lower internal resistance and is more efficient so you'll get better run times with lipo's as apposed to NIMHs. Also, don't forget the power delivery of a lipo is directly related to it's capacity so you can't go too small with a lipo's capacity.
