Description: Is there anything an Arduino can’t do? Well, for one, most of them can’t

be powered directly from a 3.7V LiPo battery; much less charge and monitor that

battery. The SparkFun LiPower Shield takes care of this by combining the

functionality of two of our favorite battery power boards: the Power Cell and the Fuel

Gauge.

The LiPower Shield allows you to connect a 3.7V single cell Lithium polymer battery

which it will boost up to 5V and connect to the Arduino board’s 5V pin. The on-board

MAX17043G+U IC is connected to the I C lines (A4 and A5) so that your project can

monitor it’s own power supply. The configurable alert interrupt pin on the

MAX17043G+U IC is broken out to D2 which will activate when the LiPo gets to 32%

or lower.

The charging circuit is configured to charge the LiPo at 100mA but by adding a

resistor to the supplied through-holes you can boost this to 500mA. There is a mini-

USB port on the shield which allows you to charge the battery from a USB power

source or you can supply a separate regulated 5V source on the “charge” header.
