Also are you looking for something in particular? Like extended run time (2300, 2700 or 3000 Mah batteries), Lighter weight (Li-Po's), cheap price (1000 or 1200 Mah batteries)? I run the bigger capacity 2300 and 2700 Mah batteries because I am using really powerful digital servos that use a lot of juice in my race Buggy/Truggy. In my REVO I run a 1600 Mah pack which is fine for Bashing.
