Then I read the spec sheet and found that the manufacturer does not
recommend parallel (or series) connections. I've sent them a message
including the dimensions of my battery compartments and asking for
suggestions.

If you talk to the other people (like RC) guys, discharge is not the
problem, but it is in the charging. If you were to put two packs in
parallel, provide a Y plug so that you can charge each isolated from the
other.
