Christophe upgrades the electrical system on his sailboat, Corail, by replacing two 230Ah AGM batteries with two 280Ah LiFePO4 batteries.4:55 The transition increases usable capacity from 92Ah to 448Ah, as lithium iron phosphate batteries allow for deeper discharge cycles without damage.10:35 The installation requires a new MPPT solar charge controller compatible with lithium charging profiles, as the previous unit was unsuitable.15:54 To protect the alternator from the high current draw characteristic of lithium banks, he installs a Victron Orion 12V/30A DC-DC charger, replacing a standard Cyrix battery combiner that risked drawing power from the service bank to charge the engine battery.23:26 Each new battery includes an integrated Battery Management System (BMS) to manage cell balancing and prevent over-voltage or deep discharge.11:02 The project cost approximately 1,000 euros for the batteries and necessary components.15:05 Upgrading to LiFePO4 technology requires verifying the compatibility of all charging sources, including shore power chargers and alternators, to ensure safe operation and prevent equipment failure.21:36
