Sorry, my fault: I actually test around with the "capacity bahaviour"
of the batteries (as described in another mail) and added:
- stop charging
- take voltage1
- wait 5 sec
- take voltage2
- output voltage2 - voltage 1
- start charging again
(every minute in the main charging loop)
To start and stop charging, I called charger_enable(bool); and that
made the display thread show a "charging: no".. So the charging cycle
was NOT really stopped.
BTW: By now, I have no finally result from the "capacity" testings. I
started a second test right now. This evening, I'll tell you if it
makes any sense to use such calculations or if it's useless at all.
