Suggestion for adding a battery First, thanks so much for this projec

First, thanks so much for this project. I was planning to build this multi-functional sensor and was worried about how to make the case, then I found your project.
A small suggestion: please add a battery option, even if it only lasts 20–30 minutes. That way we can move the sensor to another location without having to reinitialize the sensors every time! Looking forward to a version with battery support!

I am trying to use the Adafruit MAX17048 as a battery fuel gauge chip with a 2000mAh lithium battery attached. I hope the author can help improve the code.
