Does the controller power down automatically or do I need to take out the battery when not using it?
Hi MrBortz, for your information, there’s a ON/OFF switch at the center part of the controller, as shown in the picture below. If you are not using it, you can switch it to OFF to save the power. Remove the batteries if you are not going to use the controller for a period.
Also, please note that as the Bluetooth Controller is designed for MakeX, so we designed on purpose that there’s no auto-power-off function cause compared with power loss, the timely response response is more important in MakeX competitions. Therefore, if you want to save the power, switching it off manually is the best opinion.
