Default Batteries (again) - 2 Main Batts plus Tail Fin Batt wiring/switching

Hi,

Time to dust off a perennial topic

I looked through the archives and read Darryl Ramm's battery
presentation. Not an exhaustive search but I didn't find an answer to
my question.

At present we have two (fused) 12V 7Ah "main batteries" connected to
the Master switch via an SPDT "changeover" switch. We are adding a
smaller capacity tail fin battery as a "reserve".

Without using diode switching and keeping it as simple as possible for
multiple club pilots, I can see 3 possibilities that I've illustrated
he
http://www.avon-tech-solutions.co.nz...derBattery.pdf
- select 1 of the three batteries using two SPDT "changeover" switches
in "series"
- separately isolate the tail battery in parallel to the currently
selected master
- separately isolate the tail battery in parallel to the master switch

Each has its advantages and disadvantages. No doubt there are more
possibilities. I expect to add the recommended Volkslogger "hold up"
circuit separately (or power the logger and possibly a PDA from a
dedicated battery, much like the self contained battery/logger systems
previously discussed here on r.a.s.).

What wiring / switching schemes are you using for this 3 battery
arrangement?

Thanks for your suggestions.
Neil
