Moisture not only causes corrosion but also damages the electronics. In a LiPo battery, entering moisture
may set the battery on fire or even cause an explosion!
• As long as the vehicle is in operation you must always leave the transmitter switched on.
• When parking the vehicle, always switch off the vehicle‘s speed controller first and disconnect the drive battery from
the speed controller completely then.
Now you may turn off the transmitter.
• If the batteries (or rechargeable batteries) in the transmitter are weak, their range decreases. Exchange the batte
-
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 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.
• The motor and drive as well as speed controller and drive battery of the vehicle get hot during operation. Wait at
least 5 to 10 minutes before exchanging the rechargeable battery.
Let the drive battery cool down completely before charging it.
Do not touch the motor, the speed controller or the rechargeable battery until they have cooled down. Danger of
burns!
• If you operate the vehicle with a LiPo drive battery, the undervoltage recognition must be activated (we recommend
3.0 V/cell or higher).
With the undervoltage recognition deactivated, the LiPo battery will suffer deep discharge and be destroyed.
Loss of guarantee/warranty!
At operation with an NiMH drive battery, the undervoltage recognition should be switched off to better use the capa-
city of the NiMH battery. Terminate operation here if the vehicle slows down.
