This card is compatible with LiPo and Li-ion 11.1V, 12V or 12.6V 3-cell batteries and has overcurrent, overload and oversize projection. It also has a low current consumption of less than 30uA.
This card is used for Li-Ion batteries that do not have self-alignment. The board has a high precision circuit for voltage detection and is based on a MOS transistor.
Adafruit Micro Lipo - USB LiIon/LiPoly charger (v1)
Voltage indicator for 12V batteries. It uses a chip for voltage detection. Four LEDs of different colors are present on the PCB board, each indicating battery voltage. They are Red, Yellow, Yellow, Green, representing 20%, 50%, 80% and 100% respectively.
