Arduino - ArduinoXbeeShield (too expensive)
SparkFun Electronics - XBee Explorer Regulated (cheaper and more simple, but may have some design problems: SparkFun Electronics • View topic - XBee Explorer Regulated Bug)

Batteries:
RS Cargadores y baterías recargables de NiMH, electrónica de consumo
note: for 5 cars = 20 batteries plus 50% to recharge backups, around 30 batteries, plus 2 chargers, or a big one?
