I use the s110 v8.00 and nrf51822QFAA,the ADC for Detection of lithium battery， who can offer a example?

Hi mike

There is a blog post here with an example targeted at measuring lithium battery voltage. It is made for SDK 6.0.0. I attach another example for SDK 8.1.0 that you can perhaps use, since it is targeted for nRF51-DK.

Note that simply measuring the terminal voltage gives only a rather poor indication of the batter status.
