For KX1 I use a Li-Ion 11.V 1.5 Ah battery. This battery has 12.8V max and 2 Ah models cost about <$35 with a charger. See http://www.batteryspace.com/11.1v-2000mah---5900mah-battery-modules.aspx.
Compared to NiMH they are smaller, lighter, hold charge much longer, and are more reliable. They also handle high currents better. Because of build-in protection circuitry they are also hard to destroy.
