Some, maybe all LiFePO4 batteries are made up of individual cells wired
together in series to make up the full voltage.Â* If that setup is simply
stuffed into a plastic case and not secured, things can rattle around,
possibly allowing uninsulated interconnecting wires to short together.Â*
I might try stuffing foam into the battery case rather than filling it
with resin.Â* A fuse on the output cable should be considered mandatory.

The ASG-29E has a gas tank directly above two batteries used to power flight instruments.

Interesting that they say to add epoxy to the casing. Putting a fuse at
one of the battery terminals would be a more conventional way of
handling it, and would allow for easier battery replacement.
You are missing the point. The fuse will not protect against internal short.

No, not missing the point. The way I read it, they're talking about an
battery holder added around the battery. You wouldn't normally call
internal wiring "battery cables". Maybe something got lost in translation.

If anybody is using a battery so poorly constructed that it shorts out
internally and catches fire, that battery should be discarded immediately.
They are not adding a housing they are internally fixing it with PU resin because they had internal short circuit.
