It is the same on mine.  There is an external cable to connect
the power brick to the battery when it is internal.  The 
connector looks like a five conductor USB and is the same
on each end.

Definitely can do that.  I've done it since my battery is dead
and won't recover.  I still will operate with the battery inside
and the power brick external.  Since you have no battery, the
power brick needs to be inside.

BTW, the Voyager could run from the batteries alone but not for
too long. :)
