|
|
Hello,
I am finalizing a single alt dual battery installation in my Lancair
360 and generally following the diagram in figure 17.6. According to
this diagram, with both the aux bat and main bat contactors open, the
aux battery is isolated from the endurance bus and essentially reduces
total endurance by half. Why not tie both batteries together to feed
the endurance bus through the E-Bus Alt Feed Switch? Not only do you
have both batteries working for you, but the current drain from the
aux bat contactor is eliminated.
I'm definitely electrically challenged so what am I missing here?
Thanks
Angier Ames
