One of the possible reasons why your RC car won’t turn on when the battery is charged could be loose connections between the battery and the car. Loose connections can cause poor electrical flow which could lead to a malfunction of the car.



To fix the loose connections, follow these steps:

  • First, check the battery terminals and clean them if they are dirty or corroded.
  • Check the wiring that connects the battery to the car and make sure that none of the wires are frayed or broken.
  • Check the connectors where the battery connects to the car and make sure they are tight and secure.
  • If you find any loose connections, tighten them up or replace the faulty connector or wire.
  • Once you have tightened up all the connections, test the car to see if it turns on.


Loose connections can be a simple problem to fix. Regular maintenance and cleaning of the battery terminals and connectors can prevent this problem from happening in the future. If fixing the connections does not solve the problem, there may be other underlying problems that should be checked by a professional.

Malfunctioning electronic speed controller

Malfunctioning electronic speed controller



If your RC car won’t turn on even when the battery is fully charged, there may be a problem with the electronic speed controller (ESC). The ESC is responsible for controlling the speed and direction of the motor, and if it’s malfunctioning, your car won’t work properly.

Possible Causes

There are several reasons why your ESC may be malfunctioning. One common cause is overheating, which can occur if you run your car for too long or if you have a powerful motor that strains the ESC. Another possible cause is a short circuit, which can happen if your wiring is improperly installed or if there’s a problem with the motor.

What to Do

What to Do

If you suspect that your ESC is malfunctioning, there are a few things you can do. First, check to make sure all of your wiring is properly installed and that there are no loose connections. If everything looks good, try resetting your ESC by disconnecting it from the battery and then reconnecting it after a few minutes. If that doesn’t work, you may need to replace the ESC entirely.

If you do need to replace your ESC, make sure to choose one that’s compatible with your motor and battery. It’s also a good idea to choose an ESC with thermal protection to prevent overheating. If you’re not comfortable replacing the ESC yourself, take your car to a professional hobby shop for assistance.
