Lithium Polymer Batteries (LiPO)
Arduino analogue read.

LiPo Batter smart lead Pinout
For this example we used a 3s LiPo battery.
It appears that the voltage output is accumulative and does not reflect the voltage of each cell.
The Arduino analogue ports have a maximum input voltage of 5 volts.
We can only measure the voltage between GND and S1. We will not be able to measure the voltage of any other cells.
Connect the LiPo smart lead to the Arduino
The analogue signal reads the voltage and converts it to a value between 0 and 1023.
To convert the signal to volts, divide the analogue data by 1023 and multiply by 5 volts.
Connect the Arduino to your computer. Ensure you’re using the right COM port and board type and UPLOAD the code.
Open the serial monitor (Tools>Serial Monitor) to see the values.
