For my robotics project I would like to utilise readily available mobile phone 'power banks' to simplify the power system for my robot. However, such power banks output 5V, great for the logic systems but not for the motors.
I was wondering if I could wire the outputs of two power banks in series and get 10V or is this a very bad idea? Should I wire them in parallel and use a boost converter? Is a custom solution using 'ordinary' Li-Po batteries and associated charging circuit the best answer?
- This will be a two wheeled robot.
- 5V Logic
- 7+V Motor driver
