The second battery was previously only a small thing ( Dekka AGM designed for snow skis etc) and I kept a 15 plate Century N70 in the tray for stays longer than overnight. The battery box below the passenger seat was just too small. To free up space and prevent possible cable rubbing issues I had to enlarge the battery box towards the door frame this allowed the fitting of 2 batteries with a footprint of 250 x 190. I will get a Supercharge 80 A.H unit this afternoon.
