Amped Outdoors 4 Bank 12V On-Board Battery Charger

The Amped Outdoors 4 Bank 12V On-Board Battery Charger is designed to charge up to four 12V batteries, with four charging banks delivering up to 10A each. It provides a convenient charging solution for fishing boats equipped with multiple batteries, including compatible 12V, 24V, 36V, and 48V battery systems assembled from individual 12V batteries. Each charging bank features selectable modes for LiFePO4 lithium, AGM, and flooded lead-acid batteries. Its IP67-rated waterproof construction, lithium battery wake-up function, and integrated electrical protection make it a practical option for permanent on-board charging installations. WHY THE AMPED OUTDOORS 4 BANK CHARGER WORKS Flexible Charging for Multiple Battery Configurations: Four independent 12V charging banks allow you to charge up to four individual 12V batteries. This can accommodate compatible systems using one 12V battery, two 12V batteries in series for 24V, three for 36V, or four for 48V. Each battery is charged through its own 12V bank. Selectable Battery Modes and Lithium Wake-Up: Each bank supports LiFePO4 lithium, AGM, and flooded lead-acid charging modes. The lithium wake-up function can help reactivate compatible batteries in low-voltage protection mode by holding the bank's mode button for 3 to 5 seconds. Marine-Ready Construction: IP67-rated epoxy-filled construction, an aluminum heat-dissipation plate, and a waterproof cooling fan are combined with protection against short circuits, reverse polarity, overcharging, and overheating. The Amped Outdoors AO-0330M is particularly useful for fishing boats with multiple 12V batteries, including compatible trolling motor battery banks and separate marine electronics or starting batteries. Its four-bank design helps simplify charging between fishing trips.

It does not provide a dedicated 24V, 36V, or 48V charging output and must not be connected as though it does. Before charging batteries connected in series, confirm that the battery manufacturer permits individual-bank charging in that configuration and follow the charger's installation instructions. Select the appropriate charging mode for each battery. View Amped Outdoors Warranty Information
