Mike,
If it's an option, keep the same battery and add a second alternator.
True, you could go with a bigger battery, but my engine is bigger than
yours and the 680 works fine. A second alt is easy (unless mounting is a
problem), more reliable than batteries (many will argue that one, but my
auto store always sells more batteries than alternators mmmm...) and
adds less weight. Better to be up there with 2 alternators than two
batteries worth diddle. You do need enough juice to keep the alternator
excited and that varies with the brand.
I've got two alternators, one battery, dual EI and plenty of
reliability. If I shut the alternators off, my machine runs for almost
an hour on the 680 with dual EI before falling out of the sky (tested on
ground only).
This is a very old argument and everyone has their own opinion about
his/her mission. The fact that we are all still here talking about it,
lends itself to the idea that either solution is viable and reliable as
long as you respect the limitation of each.
