crappy,ill-considered system.
I tend to agree. I different sort of "enough of the bo***cks", right ?.
You can only take things so far via the use of diplomacy
The number of areas that have been identified here as indicative of poor
design are many, but for yet another, consider this: If the battery system
is designed to disconnect when the voltage reaches a low limit, the
contactor in the box must be energised (Normally closed contact). When
the battery reaches a low enough level for the contactor to drop out, the
battery becomes connected again. This would eventually discharge the
battery to zero volts, turning it into scrap.
As for the low voltage limit "reserve", I find it difficult to believe
that such a design would pass any design review. Consumer electronics,
perhaps, but not for aviation...
