I am using the EZ-B v4 Wi-Fi Robot Controller to replace the receiver in my RC car and make it into a robot . The 7.2 V battery powers both the motor and is connected to the ESC which then plugs into the receiver and powers the receiver also . The other servo for steering is also powered by the connection of the ESC to the receiver . Can you tell me how I should hook this up to my EZ-B v4 Wi-Fi Robot Controller . Also is the 7.2 Battery in the car OK to power everything or should the EZ-B v4 Wi-Fi Robot Controller have its own 7.4 Lipo power source .
