I cant recommend Bobs book enough. www.aeroelectric.com has the book.
Every Builder/owner should read and understand it.
One of the biggest reasons I recommend it is the "simple ideas" approach Bob
has to electrical systems.
He insists you Understand what you are doing when you design your electrical
system. He does not "Recommend", but explains the relative merits and costs
of wise choices.
And just to clarify, Bob feels a well designed single alt/bat system is
10-100 times more reliable then certificated systems he sees daily.

For those that don't follow the Matronics Aeroelectic list, the
moderator now recommends 2 alternators and only one battery, replaced at
each annual inspection. His logic is that modern batteries like the
Hawker, etc. are so reliable that you aren't any more likely to lose a
battery *in flight* than a wing while alternators aren't quite that
good. If the 2nd alt. is big enough to carry essential loads, it can be
lighter than even the 12 lb battery & your endurance isn't battery
limited.
A lot tougher to install, though.
