You can measure voltage battery with voltage reference. You need voltage reference with lower reference than you expect on battery (for example 1.235 V). Then you measure this voltage with your ADC. With this measurement you can now calculate ADC reference voltage, which should be equal to battery voltage.
Solution: Measure the internal resistance. How you can do that? Apply an additional known current and measure the difference in voltage. With that you get the internal resistance and with the measured current from above, you get the real battery voltage.
For example if you measure 300 with your ADC and your reference voltage Vr is 1.235 V then your battery voltage Vb is 4.2 V. Another similar, but more complex way is to use voltage divider on battery and use internal voltage of arduino for ADC reference.
To charge the battery, the buck converter is enabled while the first-stage voltage Op Amps and current-sense INA are used to measure battery voltage and charging current of the battery cell or battery pack.
The B+ and B- components are from the positive and negative terminals of the battery. Since the actual battery voltage might be higher than 5 V, the typical Op Amp power supply is 12 V. The TLV07, INA188 and INA125 all have 36 V max (±18 V) supply voltage, meeting system requirements.
