So I just bought this 2010 550i M sport..I won't drive it much. Once a month maybe?!? and never in the winter. The question is, since it will be sitting so much should I keep a battery tender on it or disconnect the battery?!!?

NEITHER! Drive the car, man! That beast is meant to be driven! Even if you start it and drive it around the block once a week. Such a shame!

JIC if you’re gonna park it that much would recommend battery tender.......disconnecting could create unnecessary problems and is not a good idea for all those electronics.
But +1 for me also on the drive it like you stole it part....lol

Drive it. Lots.

But if you can't, a tender is better than disconnecting as CM says. CTEK makes a variety of nice tenders.
