Radio controlled models battery chargers?

A radio-controlled car is a powered model car driven from a distance using a radio control system. Inputs from joysticks on a transmitter are sent to the car's onboard receiver. Radio-controlled cars can range from simple "stop and go" toys to competitive racing models, which feature all the complexity and adjustability of their full size counterparts. Building, driving, and modifying radio-controlled car kits is a popular hobby.
