teries 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 supplying the engine though 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.

Do not touch the motor, the speed controller or the rechargeable battery until they have cooled down. Danger of
burns!
