A “battery fuel gauge” is integrated in the RK809. Using
the proprietary algorithms and the sensed battery current
and voltage, the gauge can accurately calculate the battery
capacity based on the charging/discharging characteristics
of the battery preloaded in the system. The gauge then sends
the battery capacity information to the processor through
the I2C interface.

Dedicated charging port (DCP)
- This is a standard wall charger capable of at least 1500mA.
