NOCO 4 Bank Marine Battery Charger

Product Description

NOCO 4-Bank On-Board Marine Battery Charger

The NOCO GENPRO10X4 is a 12V smart multi-stage lithium and lead-acid battery charger and maintainer engineered for on-board mounting in marine, RV, golf cart and other multi-battery systems. It delivers up to 40A total (10A per bank) with chemistry-specific charge profiles for Flooded, AGM, Gel, MF, EFB, Calcium, and Lithium (LiFePO4). With IP68 waterproof construction and independently selectable modes, it’s ideal for boats with trolling motors, house bank, starting battery and other multi-bank setups. Designed with NOCO engineering, it prioritizes safety, reliability, and long battery life.

GENPRO10X4 Features:

• Multi-Bank 10A × 4 Output – Independently charges four 12V batteries with up to 10 amps per bank for fast recovery
• Individually Selectable Modes – Specific profiles for Flooded, AGM, Gel, MF, EFB, Calcium, and LiFePO4 
• Waterproof IP68 On-Board Design – Fully sealed for permanent installation in marine and other wet environments
• Automatic Maintainer Mode – Safe for long-term connection with zero overcharge – connect it and forget it
• Integrated Thermal Sensor – Adjusts charging to ambient conditions to prevent under- and over-charging
• Advanced Diagnostics LEDs – Quick status and fault indication for standby, reverse polarity, high voltage, and bad battery
• Built-In Protections – Short-circuit, open-circuit, overheat, overcharge, spark-proof, and reverse-polarity protection
• Includes Ring-Terminal Leads & 72-Inch Cables – Simplifies permanent installs with flexible routing
• Force Mode – Starts charging deeply discharged batteries below 1 volt

Automatic Battery Charger and Maintainer

This NOCO 4 bank battery charger uses a smart, multi-stage profile that rapidly charges, then optimizes and maintains each battery without overcharging. Selectable modes tailor voltage and behavior for 12V Flooded/AGM/Gel/MF/EFB/Calcium and 12V lithium (LiFePO4) batteries—lithium mode is intended for packs equipped with a Battery Management System (BMS). An integrated thermal sensor compensates charge in cold and hot conditions to avoid under-charging in low temperatures and over-charging in high temperatures, and Force Mode can initiate charging on batteries below normal detection voltage (down to ~0V).

Why Choose the GENPRO10X4?

As the next-generation successor to NOCO’s GEN4, the GENPRO10X4 is 10% smaller yet delivers 33% more power per bank while adding lithium and repair modes for broader compatibility. Independent bank control makes it a perfect fit for boats with trolling motors plus a start battery, RV house/start banks, and other multi-battery setups. Its IP68 sealed construction and robust protection suite are built for life on the water. With wide-range AC input, 72-inch leads, and ring-terminal convenience, installation and daily use are straightforward. A 3-year limited warranty and NOCO’s track record in on-board chargers make it a dependable choice for marine and RV power management.
