The Duckiebattery is a custom-designed smart power bank for robotics applications.

It is special because it can communicate to the connected computer (e.g., Raspberry Pi, Jetson Nano, etc.) via USB, enabling a number of autonomous behaviors.

Moreover, it is designed to provide continuous output in all operating conditions: in charge (for development), not in charge (for autonomous operations), when plugged in, when plugged out. Most power banks on the market will drop output voltage for a few milliseconds when plugged in/out, causing the robot to reset. 


  • Dimensions:  62 x 100 x 24.5 mm

  • Weight: 189g (fully charged) 

  • Capacity: 10 Ah at 3.7V (37Wh)

    Shipped in timely manner. Works as expected. Was only surprised it arrived pretty much "empty" (no LED indicator at all) but charged to full over night. Wonder what the standby/storage self discharge or circuit idle consumption is and if I have to watch and keep it charged when not using for a longer time? Deep discharge is no good for it.

    I had missing parts that the project store supplied when they didn’t have to do so. I’m a happy customer.
