What this video covers

Javi completes a LiFePO4 battery installation on his boat in Trinidad, upgrading to two 300Ah lithium batteries.5:16 The system configuration uses a specific parallel wiring method where each positive terminal connects to a busbar with equal-length cables, and each negative terminal routes through a shunt to the busbar to ensure balanced draw.9:04 The solar array now totals 670 watts for the house bank, distributed across multiple regulators, plus a dedicated 50-watt panel for the engine starter battery.5:03 A new battery monitor replaces the existing NASA unit, which lacked lithium calibration.9:17 The installation includes a 1200-watt inverter protected by a 200-amp fuse.6:26 Javi notes that subscribers recommended upgrading the current battery fuses to Class T or MRBF types to better handle the high potential short-circuit amperage of lithium cells.7:09 While the system currently functions well, Javi plans to replace the existing fuses once he sources the appropriate hardware.8:11
