WoW Bob,
that was a story which was expected.
If somebody has an obsession to update for a
LiFePo style battery, I would carry always omboard
a spare one (or have a dual system and not forget
a 2nd master on).
10 minutes is an awful short time to have
electricitet in the case alt/chg failure - that is
an another reason to have a dual system (if you
are a LiFePo - user boy).
Cheers, Raimo

Raimo,
I too have been known, on a rare occasion, to
leave the master on. I think I've done that three
times in the last 5 years. First two times it was
with an Odyssey 680. First time it happened I put
a charger on it and it came back like new. About
18 months later I did it again. Put the charger
on it and it came back. But this time I was
concerned so I replaced it with a new Odyssey and
put the old Odyssey in an old Jeep we use at the
hunting lease. It worked in that Jeep for about 4
years till my hunting bud left the key on for
about 6 months. That pretty much killed it.
Meanwhile, this spring, I replaced the Odyssey in
the Europa with a tiny little, very light (and
very expensive) LiFePo battery. The Odyssey I
took out went into the Jeep. The new LiFePo
battery seemed to work quite well for starting and
running. Eventually, I did a run-down test to see
how long it would operate the EFIS, EIS, Radio &
Xponder. Turned out, not very long. After about
10 minutes thi!
ngs started dropping off. I recharged & balanced
the LiFePo battery overnight and it was fine the
next day. BTW, I kept the charger/balancer on
whenever the aircraft was in the hanger. Flew a
couple times over the next week and parked it to
do more testing. This time I went off leaving the
master on (with the charger attached, btw). Next
day, the battery was DEAD. And I mean DEAD.
Would not accept a charge. I put a new Odyssey
back in the aircraft and plan to stick with them
---From now on.

I have a little Odyssey story:
once I forgot my IBBS (Integrated Battery Backup
System) on for several weeks, which gives juice to
my Gemini ADI (Tru Trak). It went empty and so
went finally my lovely Odyssey. Normally there is
like fixed 12,58 V but now hardly 4 V (four). I
had a must to fly so I elected to fire upp engine
w an external battery. I run the engine say 20
minutes and after that session it was fireable by
Odyssey only. I never noticed any failures in that
brave battery but just in case I ordered a new one
(Odyssey retail shop is just 10 km from here). Now
I have a reserve battery, which is year modell
2006, has been in use 6 years, went totally empty
and still a new like. So far I will carry those
extra kilos happily - want to hear more reports
before updating more modern batt techs.
Cheers, Raimo
