taller battery holder/clips for Ventus 2?

Does Schemp-Hirth make molded clips/restraints that will fit the
taller batteries, or am I on my own?

Frank,

To answer your question directly. No factory replacenment that I know
of, but pretty easy to mod the factory box. Either cut and extend the
current tabs or put outside tabs and use a bungie doughnut.

Larger batteries means a change in weight.
Do not forget to update the W&B.
You never know when you will get ramped by some FAA guy who will
notice the non-factory issued battery straps. It can be a very
slippery slope from there

Well that's an interesting observation. Do you update your basic
weight and balance data when you load water? Is your weight and
balance then invalid when you dump before landing?

My official weight and balance data does not include the batteries
since they are not required equipment. I consider batteries to be
optional/variable as are pilot mass and arm, water ballast mass and
arm, drinking water, and trim disks. All these are calculated on
page 2 of my W/B spreadsheet and do not appear in the weight and
balance data that was submitted for airworthiness inspection and
carried in the cockpit.

Page 2 of my weight and balance spread sheets allows selection of 1,
or 2, or zero batteries. If I change the battery type and mass I
would update the protected battery mass data on that sheet, but no FAA
inspected data would change.

I understand the situation may be different in countries ruled by
EASA.

Hey Frank,

When I bought my 2bx I modified the battery holder to accommodate the
taller batteries. I actually fabbed up a strap just like the factory
one -- only taller. Made it out of a few layers of fiberglass and
re-assembled the unit just like it had been before. Now the taller
batteries slip in easily. Piece of cake.
