Raspberry power consuming


#1

First of all, I’m italian so please don’t be afraid of my english.
I have to choose a lithium battery for a robot controlled by brickpi but I have to know how much power (Watts) I need to make the robot work. Any ideas? Thank you, Simone

Hi Simone,
First, be very careful with Lion batteries. If you short them, you can start a fire.
Each motor consumes about 1-2 Amps depending on the load. The Pi can consume up to 1A as well. You should be ready to supply 3-4 Amps at 9-10Volts.
