LiFePo Refit Part 23 AC

Hi Eric,

The advice I got from Fidel was specific to batteries mounted high in
the vertical fin.Â* Think of an inverted pendulum.Â* The visible damage
appears as long cracks in the gel coat partially around the tail boom at
the leading edge of the base of the fin.Â* I wouldn't be surprised that
there would be damage to the underlying structure, but I have no direct
knowledge of that.Â* I doubt there's any mechanical problem with fuselage
mounted batteries, though I always removed mine so that they'd be fully
charged when I arrived at my destination.Â* They were ease to remove,
however.

I'll second the recommendation on batteries OUT for trailering.Â*
Especially tail fin installs.

Is that based on gel coat cracking (the original reason for removing
the tail battery), the potential for fires caused by the battery while
trailering, or to protect the battery from damage during trailering?

Removing the main batteries from a Schleicher motorglider (ASH 26E and
later), and DG motorgliders is very time-consuming. Since I'm not
aware of any problems caused by leaving the main batteries in during
trailering in these gliders, I think removing and replacing them is
likely to cause more problems than it avoids.
