Hey guys, I am trying to make a project using arduino uno and 3 liion batteries.
Each liion batttery sometimes charges upto 4.1V and therefore the total v is 12.3V.
Can i directly connect this power supply to arduino bu connecting it with the vin pin.
I also need to measure the voltage of the battery using a voltage divider.
Anyone have any idea on how my components should be connected ?
Edit: I will also be powering 4 brushless motor with the same battery.
