NOCO GEN5X2 2 Bank Marine Battery Charger and Maintainer 10A

NOCO GEN5X2 2 Bank Battery Charger & Maintainer

The NOCO Genius GEN5X2 is a compact, waterproof onboard battery charger designed for 2-bank 12V battery systems across marine, RV, and powersports applications. This smart battery charger and maintainer delivers up to 10 Amps (5A per bank) with individually selectable profiles for Lead-Acid (Wet, AGM, Gel, EFB, MF) and Lithium (including LiFePO4 with BMS). With IP68 sealing and a simplified mounting system, it’s ideal as an onboard boat battery charger for bilge and engine compartments. Informative charging LEDs ensure user-friendly operation, while advanced diagnostics and temperature compensation enhance safety. Backed by NOCO Genius engineering, the GEN5X2 provides reliable, automatic battery charging and maintenance for season-long confidence.

GEN5X2 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

Charging Algorithm & Chemistry

The GEN5X2 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.

Why Choose the GEN5X2?

As NOCO’s next-generation onboard marine charger, the GEN5X2 packs advanced technology and more features into a smaller, lighter footprint single-bank systems. Its IP68 waterproof build and low-profile mounting make it a dependable marine charger for harsh environments. Multi-chemistry support, wide AC input, and advanced diagnostics simplify everyday use and seasonal storage. With NOCO’s proven Genius platform and a 3-year limited warranty, the GEN5X2 is a practical, reliable choice for an onboard marine battery charger and maintainer.
