House Battery for H33
I added golf cart batteries to my 2004 H33 (from Sams club). The boat came with two #24 12V batteries. I was able to fit two golf cart batteries also. I wired such that I had 3 banks: House (golf cart batteries); Start (one of the existing 12v batteries); and an 'extra' bank, utilizing the other 12v battery. The battery charger has 3 outputs, so each is charged independently from shore power. I discarded the existing 1-2-all switch, and added on/of switches for each of the banks, and one to parallel the 'extra' bank to the house if needed. Michael
