The wire is definitely cuttable, it states so in the various listings for it. As for whether it can be used without a controller I don't know to be honest, but to answer your other question the batteries are in series (i.e. 3v).
The lighting source itself is in the actual wire, apparently it is copper wire coated with a luminescent coating I assume you are effectively exciting the wire itself to produce some heat which in turn produces the lighting although having said that they don't seem to get hot.
Delivered they come with a pre-wired plug and socket on the controller and the end of the wire bundle, the other end of the wire has a clear protective cap. I'll see if I can investigate closer, but I can see numerous uses for this stuff
