The NOCO GENPRO10X3 is an ultra-rugged 3-bank onboard marine battery charger delivering 30 amps of total power—10 amps per bank—for independently charging and maintaining three 12-volt batteries up to 230 amp-hours each. Compatible with all lead-acid and lithium-ion battery types, including flooded, gel, AGM, and deep-cycle, the GENPRO10X3 ensures fast, safe, and efficient charging across multiple battery banks. Each bank is fully independent and features selectable modes—12V, 12V AGM, 12V Lithium, and 12V Repair Mode—along with smart thermal compensation to adjust charging based on ambient temperature. Designed to bring deeply discharged batteries back to life, it charges down to 1-volt or initiates zero-volt recovery with Force Mode. Built to withstand the toughest conditions, the charger is IP68-rated waterproof and tested against extreme vibration and submersion. Its anti-vibration mounting system simplifies installation in any orientation, including upside down. Certified to UL1236, ISO 8846, and compliant with 33 CFR 183.410, the GENPRO10X3 is engineered for professional-grade marine, RV, and commercial onboard use. Included in the box is the GENPRO10X3 30-Amp 3-Bank charger with 72-inch DC cables featuring 3/8-inch (M10) eyelets, a 72-inch Type-B AC cable, six self-tapping mounting screws, a user guide, and a 3-year warranty.
