Performance of
your LiPo's under
real conditions i.e.
when flying.
Not only does it display
real time voltages
of each cell within
the pack on one screen,
it also stores the
lowest voltage of
each cell since the
unit was connected
to the battery. This
information can be
used to determine
when a cell within
the pack is about
to fail. It also has
a low voltage buzzer
which can be used
to stop a cell being
over discharged.
