Resources and Going Further

The SparkFun Battery Babysitter and the BQ27441 Arduino Library are both open-source, so there are plenty of resources to go around, including:

If you'd like to learn more about the BQ27441-G1A LiPo Fuel Guage, TI has published an excellent 59-page Technical Reference manual, plus, of course, there's the datasheet.

For more information on the BQ24075 LiPo charger, the datasheet should have all of the information you might need.

The Battery Babysitter can be incorporated into just about any LiPo-powered project out there. If you're looking for a little project-inspiration, check out some of these great SparkFun tutorials:
