What this video covers
A Boston Whaler 325 Conquest required an electrical system upgrade because the factory AGM house bank could not support the owner's electronics and appliance loads without frequent engine idling.1:16 Pacific Yacht Systems replaced the AGM house bank with four lithium-ion batteries and installed a Victron MultiPlus 3000W inverter charger.2:01 The new configuration utilizes two Orion XS DC-to-DC chargers to manage lithium charging from the engine alternators, replacing the original automatic charging relays (ACRs).6:28 A Cerbo GX unit provides centralized monitoring, connected to a shunt to track all system loads.2:07 The installation requires routing dedicated power to the Cerbo GX directly from the house bank to ensure uninterrupted monitoring during power failures.4:30 All negative load cables must pass through the shunt to ensure accurate data reporting on the Cerbo GX display.15:19 The refit retains the two AGM starter batteries, now linked by a single ACR for emergency parallel starting.6:16 Upgrading to lithium and controlled DC-to-DC charging provides increased usable capacity and eliminates the need for engine-based charging at anchor.7:10
