The owner of the sailboat *Regina* upgraded the vessel’s electrical system to a 600Ah lithium (LiFePO4) battery bank, replacing a heavy lead-acid setup.▶ 0:14 The new system includes 670 watts of solar panels—a mix of rigid and flexible units—and a 400-watt wind generator.▶ 5:09 To manage the charging, the installation utilizes four Victron solar charge controllers and a Victron Orion-Tr Smart DC-DC charger to regulate alternator input.▶ 7:27 The upgrade significantly reduced the boat's total weight and battery volume by two-thirds.▶ 8:08 After one month of use in the Caribbean, the crew reports that the system maintains a state of charge above 92% even with heavy use of the watermaker, autopilot, and Starlink, whereas the previous system required frequent engine runs.▶ 11:36 The host notes that while 670 watts of solar is sufficient for their current consumption, it would be inadequate for high-draw appliances like an electric stove.▶ 15:10 The transition required replacing the battery monitor and adding a DC-DC charger, but the owner confirms the reliability and longevity of lithium make it a superior choice for long-term cruising.▶ 19:11
