Amped Outdoors 3 Bank 12V On-Board Battery Charger

The Amped Outdoors 3 Bank 12V On-Board Battery Charger is designed to recharge up to three 12V batteries using three independent charging banks, each delivering a maximum output of 10A. It provides a practical charging solution for fishing boats equipped with multiple batteries, including compatible 12V, 24V, and 36V battery systems assembled from individual 12V batteries. Each charging bank features selectable modes for LiFePO4 lithium, AGM, and flooded lead-acid batteries. With IP67-rated waterproof construction, a lithium battery wake-up function, and integrated electrical protection, this charger is designed for permanent on-board marine installations. WHY THE AMPED OUTDOORS 3 BANK CHARGER WORKS Flexible Charging for 12V, 24V, and 36V Systems: Three independent 12V charging banks allow you to charge up to three individual 12V batteries. This includes compatible systems using one 12V battery, two 12V batteries connected in series for 24V, or three 12V batteries connected in series for 36V. Each battery is charged through its own 12V bank. Selectable Charging Modes and Lithium Wake-Up: Each bank supports LiFePO4 lithium, AGM, and flooded lead-acid batteries. The lithium wake-up function can help reactivate compatible batteries in low-voltage protection mode by pressing and holding the bank's mode button for 3 to 5 seconds. Marine-Ready Construction and Protection: The IP67-rated epoxy-filled construction is designed for marine environments. An aluminum heat-dissipation plate and waterproof cooling fan work alongside protection against short circuits, reverse polarity, overcharging, and overheating. The Amped Outdoors AO-0331M is particularly useful for fishing boats equipped with multiple 12V batteries, including compatible 24V and 36V trolling motor battery systems. Its three-bank design simplifies battery charging between fishing trips while allowing each battery to be charged individually.

It does not provide dedicated 24V or 36V outputs. For compatible battery systems made from two or three 12V batteries connected in series, each battery must be charged through its own 12V bank. 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. This charger is not designed to charge a single 24V or 36V battery directly. View Amped Outdoors Warranty Information
