The GENPRO10X4 is the ultimate 4-bank onboard marine battery charger, delivering 40 amps of total power��10 amps per bank��for charging and maintaining up to four 12-volt batteries rated up to 230 amp-hours each. Built for professionals, this charger supports all battery chemistries, including lead-acid and lithium-ion, and is ideal for complex marine, RV, and multi-bank setups. Each bank operates independently with selectable charging modes��12V, 12V AGM, 12V Lithium, and 12V Repair Mode��and features advanced thermal compensation to maintain optimal charging in any climate. Able to charge batteries down to 1-volt, or activate Force Mode to recover zero-volt batteries, the GENPRO10X4 ensures complete control and unmatched reliability. Housed in a fully sealed, IP68-rated enclosure built to withstand full submersion, shock, and vibration, this charger installs easily in any orientation thanks to its anti-vibration mounting design. Certified to UL1236, ISO 8846, and compliant with 33 CFR 183.410, the GENPRO10X4 is the most powerful and dependable multi-bank charger in its class. Included in the box is the GENPRO10X4 40-Amp 4-Bank charger with 72-inch DC cables featuring 3/8-inch (M10) eyelets, a 72-inch Type-B AC cable, eight self-tapping mounting screws, a user guide, and a 3-year warranty. MEET THE GENPRO10X4�� Similar to our GEN4, only better. It’s 41% smaller and delivers 33% more power. It’s one of the best performing onboard marine battery chargers we have ever made. MULTIPLE BANKS �� A four-bank onboard battery charger rated a 40-amps 10-amps per bank for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. CHARGING MODES �� Independently charge and control each battery bank with selectable charging modes including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode for all types of lead-acid and lithium-ion batteries. ENJOY PRECISION CHARGING �� An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates. CHARGE DEAD BATTERIES �� Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts. REDEFINED MOUNTING �� A simplified mounting system allows for quick and easy installations in any direction even up-side-down with an integrated anti-vibration backing to isolate shock, vibration, and noise. DESIGNED FOR WATER �� A fully-sealed and waterproof onboard battery charger with an ingress protection rating of IP68, but has survived brutal life cycle testing, including thousands of hours underwater. WHATS IN THE BOX �� GENPRO10X4 40-amp 4-bank waterproof onboard marine battery chargers (120-240VAC) with a 72-Inch (182cm) DC cables with 3/8-inch (M10) eyelets and a 72-inch (182cm) Type-B AC cable, (2) self-tapping mounting screws, user guide, and 3-year warranty.
