Product Details

The Noco Genius GEN5X3 is a fully-sealed, waterproof on-board battery charger rated at 15 amps total—5 amps per bank—designed for 12-volt lead-acid and lithium-ion batteries. It's 37% smaller and delivers 43% more power than the previous-generation GENM3, making it ideal for marine, RV, and powersports applications including boats, pontoons, jet skis, and fishing vessels.

Advanced Charging Technology:

  • Each bank operates independently, allowing you to precisely charge and maintain three batteries simultaneously, even if they differ in type or condition
  • Selectable charging modes—including 12V, 12V AGM, 12V Lithium, and 12V Repair Mode—automatically detect sulfation and acid stratification
  • Integrated thermal sensor adjusts charging based on ambient temperature, preventing overcharging in heat and undercharging in cold
  • Charges batteries from as low as 1 volt, or use Force Mode to manually begin charging batteries down to zero volts

Rugged Marine-Grade Construction:

  • IP68 waterproof rating and has endured brutal life cycle testing, including thousands of hours underwater
  • Redesigned mounting system with integrated anti-vibration backing that isolates shock and noise, can be installed in any orientation—even upside down
  • Fully automatic operation with zero overcharge protection for 24/7 use
  • Supports flooded, gel, maintenance-free, AGM, and LiFePO₄ battery chemistries

What's Included:

  • 72-inch DC cables with 3/8-inch eyelets, 72-inch Type-B AC cable, two mounting screws, and user guide
  • 3-year warranty, engineered in the USA, certified to UL1236, ISO 8846, and 33 CFR 183.410

The GEN5X3 automatically detects battery sulfation and acid stratification to restore lost battery performance, providing stronger engine starts and extended battery life. Its compact design and professional-grade construction make it the ultimate solution for maintaining multiple batteries in harsh marine and powersports environments.
