I have a 2003 38 Open w/6CTA Cummins and have 2 banks of 3 31 series GEL Batteries.. One bank of 3 batteries are used to start the main engines and the Gen set. The 2nd set of 3 31 series GEL batteries run the house... Changed all 6 batteries 2 years ago after 17 years of trouble free use.... Never had to use the parallel switch to start the main or Gen engines.... My experience.....
