Is it possible for me to run the vex off of a small 9v battery or 6 large d cell battery’s so that it lasts really long.
Past users have used the battery (9.6 volt) from the remote control for the robot. Use the higher voltage battery at your own risk, the microcontroller can handle the 9.6 volt battery, but you never know…
Technic-R-C
You can run the Vex Controller using the Vex 9 Volt rechargeable Battery. A standard 9 Volt battery will only run it for a short while because of the current drain from Vex motors and servos. For longer battery endurance you can connect two batteries in parallel.
