Read battery voltage

[lalo-uy]

In the api there are 3 different ADC calls

analogRead(ADC)
analogReadmV(ADC)
and
getBatteryVoltage()

the AB01-V2 datasheet say:

ADC_IN2 for external ADC; ADC_IN1 is used to read the lithium battery voltage, the voltage of the lithium battery
is: V BAT = 2*V ADC_IN1

non example touches GPIO7 .
Is ok to read getBatteryVoltage() while other sensor is connected to the ADC pin?

Thanks in advance
