About this item

  • Meet the GEN5X3 - Similar to our GENM3, only better. It's 37% smaller and delivers 43% more power. It's one of the best performing onboard marine battery chargers we have ever made.
  • Multiple banks - A three-bank onboard battery charger rated a 15-amps - 5-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.
  • What's in the box - GEN5X3 15-amp 3-bank waterproof onboard marine battery chargers (120-240VAC) with a 72-Inch DC cables with 3/8-inch eyelets and a 72-inch Type-B AC cable, (2) self-tapping mounting screws, user guide, and 3-year warranty.

    Extremely high quality charger/maintainer!

    Extremely high quality charger/maintainer!
    I am using the Noco Gen 5x3 to charge and maintain two 12.8v lithium iron phosphate trolling motor batteries along with a standard 12v deep cycle cranking battery on-board my bass boat.Right out of the box I was in love with this unit... this thing is VERY well made. The button layout is straight forward and the indicator lights are very bright.Install was a cinch too. The unit has mounting slots on each side to secure it to any surface and the wiring is very straightforward with a 110v power cord and three sets of positive/negative battery connection leads.This is truely a "set it and forget it" unit. After initially setting your battery type, the charger remembers your preferences and begins charging automatically every time it's plugged in. (Side note: if you need a faster charger... the Gen 10 models double the output power... for my needs, the Gen 5 is fine).Do yourself a favor, spend a little more and get one of these Noco chargers. You wont be sorry.
