I have not done this , but I saw this unit online.
this is called a battery tender female power port. most ducati's I've seen come with a charging port on the lower left side. this would require you re- rout your charging port.
I've found it best to keep my bike on a ctek battery charger when ever I'm not riding it . either the battery on the duc hasn't enough cca/ starting nut, or there is a real drain on the power while the bike is sitting not running. if you're going to do this I would recommend getting a smart battery charger compatible with agm batteries .
I would guess that the alternator has enough power to keep the battery charged and charge a cel phone- especially at speed. I would think at lower rpm and at idle you could drain the bat.
