Displaying the battery charge level on the Serial Monitor is fine for testing but not very useful for a battery powered project. We typically what to display the current battery level somehow directly. That code be an LED bar or an LCD display. But in this example I am using a OLED, since they are very small and work nicely with 3.3V.
Now go to the private view of Thingspeak Dashboard. The Dashboard will shows the values of Battery Voltage, Load Voltage, Current and Power in graphical format as per time. You may start charging the Battery using 12V Battery Charger and observe the change in Current and Voltage on the graph.
In portable electronics designs, typical battery-monitoring systems measure battery voltage and battery current to detect when the battery needs charging or replacement. In this post, I’ll demonstrate battery-voltage and current-monitoring circuitry for cost-optimized systems using operational amplifiers (op amps).
This value is proportional to the the battery voltage. We then calculate the voltage by multiplying the analog value by the maximum voltage and dividing it by the maximum range of the analog input (1023). int value = analogRead(A0); double voltage = value * maxV/1023.0;
This allows users to monitor the battery status remotely from anywhere in the world via their smartphones or computer dashboards. The server displays the battery voltage, load voltage, current, and power, providing a comprehensive overview of the battery’s condition in both charging and discharging states.

Battery Monitoring Basics
The idea seems a pretty robust one, except that in practice, you really can''t update capacity at 0% * Battery voltage depends not only on its state of charge, but also on discharge current. This is caused by voltage drop IR due to battery internal resistance. This drop is higher at high currents, low temperatures, and for aged batteries which ...
