How to measure Lithium battery voltage

How to measure Lithium battery voltage with the nRF51 ADC

Parents
  • Is there anyway to get these links working again? They don't seem to be functional. Also, I'm assuming that the output of the voltage divider is unaffected by the capacitor.

    So with a fully charged lithium ion batter (4.2V) you would expect to see a voltage of

    4.2*(2.2/10) = .924V

    Is the functionality of the circuit as follows? The capacitor is just acting to store up some charge to dump charge into the internal capacitor used by the ADC. It is essentially acting as a low impedance voltage source for the ADC sampling circuit?

  • Stefan,

    Thank you for your attention to my questions. It is greatly appreciated. This is my first experience developing on a Nordic platform, and the design process has been made much easier through the help of you and the others you work with.
