Hi,
I found this simple, controlled battery monitor circuit online. However, I'm trying to better understand how this works and if I can make it better, by changing the resistor values. I want to monitor the voltage on a 3.7V(Nominal Voltage) Li-Po Battery, and I was wondering what the 100K resistor (R3) is for and the affects of changing the 2K resistor (R4) to something bigger for example 10K?
Thanks in advance for your help!
