12F1840 ADCIN troubles, help needed :(

Thanks, but that is a bit complicated - no need to save that much power. The battery voltage to be monitored is around 11V (3S LiPo), so divider with 470k/100k resistors should work just fine?

Look at last post.

Tried that already. Too small values and I have too large ripple going on (current consumption is 20-25A). So I settled with 750k/150k+1nf combo, works just fine.
