A great little battery widget for showing the current power status of your batteries.
Mount it underneath or next to your batteries to keep track of what needs charging and what does not.
Two versions are available:
This widget comes in two parts: a body and a lid. To attach the lid to the body, some force is required. Once the lid is on, slide it back and forth a couple of times until it runs smoothly.
Attach the Battery status widget with glue or double-sided tape.
