So I went and buy a Battery Tender for our two scooters and I was planing to install the battery tender adapter for the Super 8 150, since the Vespa lxv 150 already has one, low and behold I open the battery cover and to my surprise there is already a battery tender cable adapter installed, all i had to do is trace it, it sitting pretty on the left side on top of the left case. I wish my salesman had told me this and save me the time to plan installing it. pic included.
