ries or rechargeable batteries for new ones.
When the car‘s drive battery is weak, the car gets slower or no longer responds correctly to the transmitter.
The drive battery in the vehicle is not only used for power supply of the engine via the speed controller.
The speed controller also generates the voltage/current required for operating the receiver and the steering
servo.
 Forthis,thespeedcontrollerhasanintegratedBEC(„BatteryEliminatorCircuit“;electroniccircuitfordirect
voltage supply of the receiver without additional receiver battery).
If the voltage in the drive battery is too low, the voltage at the receiver may also drop, causing the vehicle to
no longer respond to the control commands at the transmitter.
In this case, stop driving at once (switch off speed controller, disconnect drive battery from vehicle, switch off trans-
mitter). Then replace the vehicle drive battery or recharge the drive battery.

least 5 to 10 minutes before exchanging the rechargeable battery and any new driving cycle.
Let the drive battery cool down completely before charging it.
Do not touch the motor, the speed controller or the rechargeable drive battery until they have cooled down. Danger
of burns!
