Comment(by werner):
By the way, how the PMU is set up, it will automatically stop charging
when
the battery has reached 4.2V (MBCC2.vmax) and resume when it has dropped
to
4.032V (MBCC2.vmax*96%, see description of MBCC1.autores).
So as long as the voltage does not leave these boundaries, that's just
normal behaviour of our charging hardware. The battery pack is specified
for a charge voltage of 4.2V+/-0.05V, so the MBCC2.vmax setting of
4.2V+/-1%
is as high as possible without violating the battery specification.
If this is just a GUI problem, a solution might be to read MBCS2.mbcmod
and
to display something less disturbing than a discharging battery when in
state "Battery Full mode", 10 decimal.
