About this item

  • MEET THE GEN5X3 — 37% smaller and 43% more powerful than the GENM3. It’s our most compact and advanced onboard charger yet—engineered for peak performance in the harshest marine environments.
  • MULTIPLE BANKS — A three-bank onboard battery charger rated at 15 amps total - 5 amps per bank. Independently charge 12V batteries in marine, boat, starter, and deep-cycle systems.
  • CHARGING MODES — Selectable modes for each bank: 12V, 12V AGM, 12V Lithium, and 12V Repair Mode. Independently charge and maintain all types of lead-acid and lithium-ion batteries with precision.
  • ENJOY PRECISION CHARGING — An integrated thermal sensor adjusts charging based on ambient temperature, preventing overcharging in heat and undercharging in cold for optimal battery performance.
  • CHARGE DEAD BATTERIES — Charge batteries from as low as 1 volt, or use Force Mode to manually begin charging batteries down to zero volts to recover deeply discharged or neglected batteries.
  • REDEFINED MOUNTING — A simplified mounting system allows for fast, secure installation in any orientation - even upside down - with an integrated anti-vibration backing to isolate shock and noise.
  • DESIGNED FOR WATER — A fully-sealed onboard charger rated IP68 for waterproof protection. Survives brutal life cycle testing, including thousands of hours underwater in the harshest marine conditions.
  • WHAT’S IN THE BOX — GEN5X3 15A 3-bank onboard charger with 72-inch DC cables and 3/8-inch eyelets, 72-inch AC cable (Type-B), and two mounting screws. Backed by a 3-year warranty and engineered in the USA.
