You have to find out what the MOTOR voltage is.  If it is 12 volts, then yes
batteries are connected "in series".  Just get an adapter and solder it into
the battery terminals.  But sometimes batteries are connected in ways to get
different voltages.  Like the eight batteries could be hooked up as two
stacks of four 1.5 volt batteries joined "in parallel" to give you six
volts.  That provides less voltage, but longer output capacity than one
stack of four 1.5 volt batteries.

As far as a previous posting, heck, I miss LOTS of first posts.  Dunno why.
Sorry.
