Hi Friend,
Could anyone please help me out here ?
I have two series battery with top of charge 8.4V(4.2V each cell). Battery lower cut off voltage is 5.8V.
So input supply is 5.8V to 8.4V and i have a few mA load for 5V supply as per below.
My rest of input supply voltage from battery will be drop by series resistor R or some other components.
I made some calculation here for ADC measurement but i am not sure if i am correct here. As per my assumption if 5V is output then rest of battery voltage will be dropped by resistor so GND level for microcontroler is shifted somewhere as per below.
My objective here to measure both battery cell voltage individually but i am not sure how this will be done.
How Much and how microcontroller will read ADC value. Divider voltage is 4.5V for 8.4V battery and 3.15 for 5.8V battery.
Could anyone explain here ?
This calculation is for total battery voltage. Is it possible to measure individual battery voltage for both cells ?
Thanks in advance !!!
