I have a Raspberry Pi 3B running with a Pi No IR Camera(with two infrared light sources as comes in the No IR Camera package), and a handful of sensors working on the GPIO Pins. The setup is to be mounted on a base provided with four wheels and two DC motors.. As of now, the Pi and its attachments run from the power socket. However, once it is mounted on the robot base, I will need some kind of portable power source.. Please suggest something that can run the setup for 12 hours at a stretch at least.
I know the question might be vague, please ask for the details that will be needed, and I will provide them..
Thanks in advance..
