GETTING STARTED
The MCP1630V Bidirectional 4 Cell Li-Ion Charger Reference Design is fully
assembled and tested for charging a four series cell Li-Ion battery pack (Battery Pack
should have internal overvoltage, overcurrent and overtemperature protection). The
board requires the use of an external input voltage source (+7.0V) for charging.
