## Description

The NOCO GENPRO10X4 is a high-performance, fully-sealed onboard battery charger rated at 40 amps total—10 amps per bank—built to simultaneously charge and maintain up to four 12-volt batteries. Compatible with all types of lead-acid and lithium-ion batteries—including flooded, AGM, gel, and LiFePO₄—the GENPRO10X4 delivers 19% more power in a housing that’s 27% smaller than the previous-generation GEN4. Each of the four banks functions independently, giving you the flexibility to charge different battery types, chemistries, or states of charge at the same time. With selectable charging modes for 12V, AGM, Lithium, and Repair, the GENPRO10X4 ensures optimal battery care and performance across a wide range of applications. An integrated thermal sensor dynamically adjusts the charging profile based on temperature to prevent undercharging in the cold or overcharging in hot climates. For heavily discharged batteries, Force Mode provides manual charging capability down to zero volts—critical for reviving batteries other chargers can’t detect. Built to withstand the toughest marine conditions, the GENPRO10X4 is IP68-rated for waterproofing and has passed rigorous life cycle testing, including thousands of hours of submersion. Its compact footprint and advanced mounting system make installation fast and secure in any position—even upside down—while an integrated anti-vibration backing minimizes shock and noise. Included in the box are 72-inch DC cables with 3/8-inch eyelets, a 72-inch Type-B AC cable, two mounting screws, and a user guide. The GENPRO10X4 is backed by a 3-year warranty, engineered in the USA, and certified to UL1236, ISO 8846, and 33 CFR 183.410 for marine ignition protection and safety compliance.

## Questions & Answers

**Q: Can this unit be mounted outside to maintain batteries on utility vehicles ?**
A: While it is "waterproof".... It isn't element proof. Aka the sun would likely destroy the plastic after a while. Including the cables etc... This is designed for charging boat batteries. Or well that's what I bought it for. Maybe someone else knows more about it.

**Q: Can this unit be mounted outside for use maintaining utility vehicle batteries ?**
A: Yes.

**Q: Can this unit be mounted upside down. Where the wires would be coming out the top?**
A: Yes. According to documentation the unit can be mounted in any position.

**Q: With a 4 battery parallel array can the 8 charging cables remain connected while the batteries are supplying the load?**
A: The privies is to always leave the charger on the batteries.  Works great.  We use ours for lithium batteries.  Ours are in a series, I don’t think parallel would be any different.  One thing to note, it does way 40lbs.
