As already mentioned from others, it *is* a LiIon, it has 4,2v max and
goes down to ~ 3v when empty. So the scale factor seems to be exactly the
same as for the recorder.
If your adc.c really means that getting the voltage through AN6 ever
works on the FM (I'll take a look at the source later), I'll update it
in CVS. The next thing then would be to make the charger algorithm also
work for the FM.
Especially: Is the charging done in hardware or must Rockbox switch the
charging current on and off (same as for recorder)?
Do you notice the voltage going up when the charger is connected and
Rockbox doesn't charge (turn deep discharge option on for testing this)?
