You need to get batteries for the radio transmitter and the car receiver packs.
• Radio TX needs  (8) eight AA batteries.
• Car needs (4) four AA Ni-cad batteries 2000Mah OFNA #10196 or (4) Alkaline., 
Alkaline type batteries will work, but braking will be reduced and 30 minute life.  The 
best for car, is to use a 5 cell hump receiver pack for increased voltage and longer 
life..

Recommended Option:
You may want to upgrade the car battery pack to a Ni-Cad or NiHm 5 cell 
type(600AE).  This will give more run time. OFNA #10212 1200NiMh Hump Pack and
