My RV6A had dual batteries and the Bus Manager system from Protek and a dual EFII ignition system.
What is the proper order (technique) for hooking a charger up. The charger has three settings the last being AGM for my Oddessy PC680s. Such as when to plug charger into the electric, etc.
Also, in a dual system can I charge both batteries by hookup to the alternator fat wire and would I still use AGM?
Thanks,
Ron Burnett
May you have the Lord's blessings today!

How big a charger is this? i.e. what is the
charge current? Do I presume correctly that
the charger has a 'maintenance' mode and
can be left connected indefinitely?
What is your thinking for using a 'charger'
as opposed to simple battery maintainers?
The artfully maintained AGM battery has a very
low self-discharge rated. This means that if
you fly at least once every 30 days, the
battery(ies) will be up and ready for
every flight. For long term storage like
over the winter, it's useful to use a
small battery maintainer . . . a small
almost-a-charger that offsets the tiny
self-discharge currents and keeps the
battery topped off.
The only time you need a CHARGER is when
the battery has been inadvertently depleted and
requires substantial replenishment. In this case,
having a charge rate of 3, 6, or even 10A
will get the battery back on its feet.

I'm assuming you are expecting the charger to emulated
a running alternator. To make this work, your system
would have to be powered up with both battery
contactors closed.
Charging in-situ batteries from outside
the aircraft is best managed by a charging
or 'ground maintenance' connector. Preferably
one for each battery. Of course, these
same connectors would provide a means
for applying battery maintainers for
long term storage.

Gentlemen –
I would not presume to disagree with Bob on things electric.
Just a data point from my experience.
The CherokeeJet has a Concorde behind the rear baggage bulkhead (can’t remember if it’s 25- or 35-AHr). It often sits neglected for months at a time, with little more than a touch on the wingtip and a regretfully muttered “…maybe tomorrow…” It gets no electrical support between flights (I think I plugged it up once after an extended session of fiddling with the avionics (Schumacher 1562)). I don’t remember when the current battery was mounted, but it has been many years. On those rare occasions that I do get to drag it out, the battery spins the engine happily, and has no trouble grunting the initial compression strokes.
On the other hand, I have killed several PC680s while not finishing my RV-7 project – some hooked to the 1562, others not.
My experience implies some of us worry way too much.

I have a battery doctor that I hook up occasionally and had been running some fuel pump tests. The charging voltage is 14.5 from my Plane Power alternator.
One Oddessy PC680 I replaced during condition inspection in October 2019 and the other is 20 months old.
I have over 400 hours using the Bus Manager and 260 hours with the Lycoming 0360 and EFII system.
I will check all my connections.
