How can a Raspberry Pi read battery charge data from UPS board? This page states "Integrated Maxim's fuel-gauge systems for reading battery voltage and percentage over i2c", but are there any libraries one can just install via apt? I would really like to have a widget on my task bar indicating how many percents does battery have. What would be the easiest way to accomplish that?
