What this video covers

Javi, owner of the boat Regina, manages his electrical system by alternating between two independent lead-acid battery banks to extend their service life.0:26 The system consists of one bank of three 145-amp batteries and a second bank of two 180-amp batteries.4:19 By cycling usage so that only one bank is active, charging, and discharging at a time while the other remains in total rest, he aims to double the expected 1,500-cycle lifespan of the lead-acid units.5:19 After four years of this practice, both banks remain functional.7:02 To support high-draw equipment like a watermaker and Starlink, he recently increased his solar array from 350 watts to 470 watts.0:54 This upgrade allows the watermaker to run directly from solar power during the day without depleting the batteries.3:01 He currently seeks a replacement stator for a second-hand wind generator to provide supplemental power during nighttime hours when solar input is unavailable.8:20
