I am currently wondering for a college project, if it'd be possible or not to use a power bank to build a line following robot and power both the pi 3b+, the waveform motor driver hat with 2 dc motors(BO Motor 150RPM) and a 5-channel line following sensor (Sun Flower Line Tracking Infrared).
The power banks I have have the following specs:
- 5V and 2.4A
- 5V and 2.0A
Both offer 4000mAh capacity.
My questions are:
- Will a power bank have enough energy to run the robot?
- If you can, how long would it approximately run on one power bank, before you need to recharge it/replace it?
- Is there something else that I might need to know?
