What this video covers

A liveaboard owner explains the reasoning behind a 2,200 amp-hour battery bank installed on his boat, using a real-world test at the municipal marina in downtown St. Pete as proof of concept.0:48 His design target was double average daily consumption — a 50% redundancy ratio — so he could sit at anchor with no wind, no sun, and no shore power without waking at 4 a.m. to check a low-battery alarm.0:29 The test: all three AC units running simultaneously, totalling 16,000 BTUs, set to 70°F during the day and 73°F overnight, with no shore power connection.1:08 The bank finished the night at 51% state of charge.1:28 Steven Lloyd and the team at The Yacht Rigger are the installers behind the system. The owner's principle is that oversizing a battery bank by roughly double expected demand eliminates anxiety-driven power management and keeps the boat fully livable in worst-case conditions — no solar, no wind, no hookup.0:09
