2-Batteries

I'd like to see a full write-up with diagrams, photos,
and names/addresses of places to buy parts. This would
make a good article for Soaring.

Better yet is to use diodes so that both batteries

in parallel and you're always pulling from the best
battery with no
fiddling required from the pilot. Relatively low
voltage drop diodes
are available with 18 Amp forward capacity. For redundancy,
I used two
in parallel on each battery.

If it is always drawing from the best battery, what
is the time
interval between switching.
What controls the switching. Please advise.
