The NOCO GEN5X2 is a waterproof, fully-sealed onboard battery charger rated at 10 amps total—5 amps per bank—designed for 12-volt lead-acid and lithium-ion batteries, including flooded, AGM, gel, and LiFePO₄ chemistries.
It’s smaller by 37% and delivers more power by 43% than the previous-generation GENM2, making it our most compact and advanced charger yet.
Each bank operates independently, allowing you to charge and maintain two batteries simultaneously with precision, even if they differ in type or condition.
Selectable charging modes—12V, AGM, Lithium, and Repair Mode—offer tailored charging for battery health and longevity, while an integrated thermal sensor automatically adjusts charging in hot and cold climates to prevent undercharging or overcharging.
For severely discharged batteries, Force Mode lets you manually begin charging from zero volts, a critical advantage for recovering deeply neglected batteries that other chargers can’t detect.
Engineered for the harshest marine environments, the GEN5X2 features an IP68 rating and has endured brutal life cycle testing, including thousands of hours underwater.
Installation is fast and secure in any orientation—even upside down—thanks to a redesigned mounting system with an integrated anti-vibration backing that isolates shock and noise.
The GEN5X2 comes with 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide.
It’s backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for safety, ignition protection, and marine compliance.
