What this video covers

The crew of a catamaran in Greece replaces a bank of three AGM lead-acid batteries with a single 300Ah LiFePO4 drop-in battery from Leadtime to improve electrical capacity and reliability.▶ 0:58 The existing AGM system suffered from significant voltage drops shortly after sunset, limiting the use of onboard appliances like the refrigerator.▶ 0:58 The new 12V lithium battery offers a 200A maximum continuous discharge current and a 2560W output, which exceeds the boat's peak demand from the inverter and anchor windlass.▶ 2:49 Because the battery lacks Bluetooth connectivity, the installation includes a dedicated shunt-based battery monitor to track state-of-charge, as voltage levels in lithium batteries remain stable until near-total depletion.▶ 5:35 The installation requires enlarging the existing battery compartment by approximately 2cm to accommodate the larger footprint of the new unit.▶ 9:44 The crew wires all negative leads from solar controllers, the inverter, and DC loads to the shunt, then calibrates the monitor with specific capacity and voltage parameters.▶ 11:06
