ROCHOBBY 1:6 1941 MB Scaler - Why does my car suddenly stop while driving?

A: Your RC car may suddenly stop while driving due to the activation of protection functions designed to safeguard the electronics and battery.

Details:

1. Low Voltage Cut-off Protection (LVC):

   • If the voltage of the battery pack is lower than the threshold for 2 seconds, the ESC will enter protection mode.
   • When this happens, the red LED blinks to indicate that the low voltage cut-off protection has been activated.
   • For 2S LiPo: Output reduces by 50% at 6.5V, and cuts off at 6.0V.
   • For 3S LiPo: Output reduces by 50% at 9.75V, and cuts off at 9.0V.

2. Over-heat Protection:

   • If the internal temperature of the ESC exceeds 100°C (212°F) for 5 seconds, the ESC will reduce and cut off the output power.
   • When the car stops due to over-heat protection, the red LED blinks. The output power will be recovered to normal state once the ESC cools down to 80°C (176°F).

3. Throttle Signal Loss Protection:

   • If the throttle signal is lost for 0.1 second, the ESC will cut off the output power.
   • This protection ensures that the car does not operate unpredictably if the signal between the transmitter and receiver is interrupted.

Troubleshooting Steps:

• Check the Battery: Ensure the battery is fully charged and the connections are secure.
• Monitor the ESC Temperature: Allow the ESC to cool down if it has overheated. Ensure proper ventilation and consider upgrading to a more efficient cooling system if overheating persists.
• Check Signal Connection: Make sure the transmitter and receiver are properly paired and that there is no interference causing signal loss.
• Verify Voltage Settings: Ensure that the ESC is correctly set for the type of battery you are using (LiPo or NiMH). Incorrect settings can trigger LVC protection prematurely.
