Multicell Voltage Monitoring for Lithium Battery Pack ...

In this article we will learn how we can measure the individual cell voltage of the cells used in a Lithium battery pack. For the sake of this project we will use four lithium 18650 cells connected in series to form a battery pack and design a simple circuit using op-amps to measure the individual cell voltages and display it on a LCD screen using Arduino.

Create Your Own Battery Backup Power Supplies

In my case, the power supply had an open circuit voltage of 9V and the voltage of the battery pack was about 6V. This gave a voltage difference of 3V. Dividing these 3 volts by the current of 0.008 amps gives a resistance of 375 ohms. So your resistor should be at least 375 ohms. I used a 1 kohm resistor to be extra safe. Keep in mind, however, that using a larger …
