What this video covers

Erik Aanderaa replaces the three 100-amp lead-acid house batteries on his boat, Tessie, with three 150-amp ProSupply lithium batteries.0:06 This upgrade increases the total house bank capacity from 300 to 450 amps while maintaining the same physical footprint.0:29 Each lithium unit weighs approximately 12 to 13 kilograms, significantly less than the lead-acid equivalents.0:58 The installation involves removing the existing lead-acid starter battery to access the house bank, disconnecting the old wiring, and installing the new lithium units.1:56 Aanderaa verifies the system by testing the shore charger and the engine-driven alternator, which delivers 130 amps to the bank at 1500 RPM.4:42 He calibrates the Victron monitoring system to reflect the new capacity and performs a zero-current calibration.6:27 Aanderaa emphasises that upgrading to lithium requires thicker charging cables to handle higher current demands and an external regulator to manage alternator voltage.7:17 He also uses a cooling fan to prevent the alternator from overheating during high-output charging.7:30
