Hi! Pete,
The first two worked satisfactorily for in excess of 10 years and were
only changed to a whim one has since failed but the other is still
holding charge to start my lawn mower (15 years) Not forgetting they had
some demanding requirements when operating the Jabiru 6 cylinder I think
about 1000 hours total to removal from the aircraft indicates that
chance of failure is remote so no arrangements have been made about the
worries you promote. It does have a =9CCrowbar over voltage
protection fuse in the alternator circuit=9D.
They are gel batteries so don=99t suffer swishing of liquids to
erode plates. I would want such as Lithium type to be very proven before
flying with them as an experiment. ( all statements are made in my
novice opinion!)
Regards and best wishes to all
For Christmas and onwards into 2015,

Bob,
I'm curious how you dealt with the issue of the batteries being
unbalanced with resulting cross-battery discharge, and protection
against a potentially shorted cell aggravating the situation? Did you
use isolation diodes?
Cheers and merry Christmas!

Hi! David/all.
IMHO it is the capability of the battery to give up it=99s power
when activating the starter . I use two Odessey 13ah STARTER
batteries in parallel and my high performance starter gets the 914 into
motion instantly. I also have them both mounted on the passenger
footwell with the delivery cable only needing to be about 12 inches
long . In total it is my opinion that debates about batteries always
seems to exclude the basic functions to which I refer here, so beware
of short cuts saving weight and purchase prices.

Any battery experts out there can comment on this battery for use in
Europa
