Onboard Marine Battery Charger, 30A 3-Bank (10A/Bank), 12V Waterproof, GENPRO10X3

The NOCO Genius GENPRO10X3 is a 12-volt, 30-amp three-bank professional waterproof onboard battery charger and maintainer, delivering 10 amps per bank to independently charge and maintain three 12-volt batteries at once. Fully sealed to an IP68 rating, it survives thousands of hours underwater and mounts in any orientation with an integrated anti-vibration backing. Each bank charges lead-acid and lithium-ion batteries - flooded, gel, AGM, maintenance-free, and LiFePO4 (with BMS) - using selectable 12V, 12V AGM, 12V Lithium, and 12V Repair modes. An integrated thermal sensor adjusts the charge to ambient temperature, and it charges batteries from as low as 1 volt, with Force Mode down to 0 volts. Its high 10-amp-per-bank output suits larger multi-battery boat systems. Certified to UL1236, ISO 8846, and 33 CFR 183.410.
