NOCO GENPRO10X4 4 Bank Marine Battery Charger and Maintainer 40A

Product Description

NOCO 4 Bank Battery Charger and Maintainer

The NOCO GENPRO10X4 is a waterproof onboard battery charger designed for 4-bank 12V battery systems with on-board mounting for marine, RV, golf carts and other multi-battery setups. This smart battery charger and maintainer delivers up to 40 Amps (10A per bank) with chemistry-specific charge profiles for Lead-Acid (Wet, AGM, Gel, EFB, MF) and Lithium (including LiFePO4 with BMS). With IP68 waterproof construction and independently selectable modes, it’s ideal for boats with trolling motors, house bank, and starting battery with same or mixed battery types. Informative charging LEDs ensure user-friendly operation, while advanced diagnostics and temperature compensation enhance safety. Designed with NOCO engineering, it prioritizes safety, reliability, and long battery life.

GENPRO10X4 Features:

• Smart Automatic Charging – Optimizes charge time and improves battery health with chemistry-specific control
• Individual Bank Control - Each bank can be charging a different battery type at the same time
• Automatic Battery Maintainer – Safe for 24/7 connection with zero overcharge
• Lithium Mode – 14.6V profile supports 12V LiFePO4 batteries with BMS for safe, fast charging
• Low-Voltage Recovery – Recovers deeply discharged batteries, even down to zero volts with Force Mode
• Integrated Thermal Sensor – Adjusts charging in heat or cold to prevent over- or undercharging
• IP68 Waterproof Construction – Withstands marine environments and other wet applications
• Low-Profile Design – Conveniently mount onboard for clean installs in tight spaces
• Protections – Spark-proof, reverse-polarity, over-voltage, over-heat, short/open-circuit with status indicators

Smart Battery Charger and Maintainer

The GENPRO10X4 uses a smart, multi-stage algorithm that brings the battery up efficiently (bulk), completes the charge without stress (absorption), and then maintains it safely for storage (maintenance/float behavior). Selectable modes for each bank tailor voltage and behavior for 12V Lead-Acid (Wet, AGM, Gel, EFB, MF) and 12V Lithium (LiFePO4) batteries with an internal BMS. An integrated thermal sensor compensates for ambient temperature and adjust target charging voltage accordingly. The charger can detect as low as ~1V, and with Force Mode, you can initiate a charge cycle from zero volts when appropriate. For long-term storage, its automatic maintainer function supports 24/7 connection.
