I'm sure others will weigh in soon.

I believe that this only applies to very old power converters that still use the battery to make the output smoother.
Any newer models don't need that. In fact, my Jayco trailer mentions the battery as being a "dealer installed option".
I contacted both Jayco and Progressive Dynamics (the power center maker) with this very question. Both replied that it is perfectly fine to run the power center and loads in the trailer without a battery.
In some trailers, there may be one exception: if you have a heavy slide with a big motor and a small power center, the power center alone *may* not be able to supply the starting amps of that this motor needs. In that case, a battery may be needed to help.
So I would not run the slide motor (if you have one) unless you are sure it draws less than the power center rating on startup. But, for everything else, it is just fine to run without a battery.
