As I know , if only 2 wires , you can not access the Li+battery status , you can just get voltage value from PMU
There always another 1 wire to get the communication with MCU in battery module 2014-11-25 8:52 GMT+08:00 <[email protected]>: > Hi All, > > I connected a rechargeable Li+ battery to my BBB TP5, TP6, TP7, and TP8.
