RE: *Airtronics RD8000 2.4 GHz*
E-Bay. Go to E-Bay and type in 9.6v battery then on left of screen click on Toys and Hobbies. There you will find 2500 mah 9.6volt packs for cheap money $34.95 for two 2500 mah packs shipped. Good deal. Upon receiving any new battery pack make sure polarity...positive and negative wires are in the correct location before plugging a new foreign pack into your transmitter.
