I have posted on my web site the electrical schematic and load analysis 

that I am considering.  The electrical design is a single battery, dual 

alternator design.  Comment if you would.

Thanks to all who have before for a great load analysis layout for the .

I would consider a dual battery instead of a dual alternator.

All I know about electricity is that the paddles tingle after the juice goes

into them.

Really?  I guess as Bob N. says, your design goals must be the deciding

factor on your decision.



Either option is viable.  And even though the U.S. Army doesn't get it right

all the time, they've opted for a single battery, dual alternator design in

their single-engine helicopters.  Of course, the option for the 2d battery

is there, but that's usually left for cold-soaked aircraft needing the amps

to start in the middle of the night with no ground power units available.



Now if you plan on a hangared plane where you can hook up a ground power

cable if it's too cold, you may want to choose the single battery/dual

alternator setup.  Then you don't have to immediately start the 30 minute

"my-battery-is-going-dead" clock if your only alternator fails that powers

your glass panel.



I'm sure there are some more nice battery/alternator wars in the

aeroelectric list archives that go into choices due to weight, c.g., spare

engine pads, etc. in addition to original design goals.

 For what it's worth, I chose to use both dual alternators, dual batteries 2 busses (I can connect the 2 if needed).  Just now into ground runs before first flight, and I am happy that I decided to go this way - redundancy for intended IFR flight.
