NOCO GENIUS 2X4 6V/12V 4 Bank 8A Battery Charger & Maintainer

Product Description

NOCO Genius 2X4 Multi-Bank Battery Charger & Maintainer

The NOCO GENIUS2X4 is a compact 4-bank smart battery charger designed to charge, maintain, and optimize multiple batteries at once in 6V & 12V systems. Delivering 2 amps per bank with individually selectable profiles for Lead-Acid (Flooded, AGM, Gel, EFB, MF) and Lithium (including LiFePO4 with BMS)—perfect for motorcycles, ATVs, marine batteries, lawn equipment, and other small battery systems. Informative charging LEDs ensure user-friendly operation, while advanced diagnostics and temperature compensation enhance charging optimization. Built with NOCO’s advanced charging technology, the GENIUS2X4 automatically detects battery condition and adjusts the charging process to deliver a safe, efficient charge every time.

Features & Benefits

• Smart Automatic Charging – Optimizes charge time and improves battery health with chemistry-specific control.
• Independent Charging – Charges and maintains 4 batteries simultaneously with dedicated outputs for each bank.
• Individual Bank Control - Each bank can be charging a different battery type at the same time.
• Automatic Maintenance Mode – Maintains batteries during long storage periods without risk of overcharging.
• Multi-Chemistry Compatibility – Supports 6V and 12V batteries including flooded, AGM, and gel, plus compatible lithium batteries.
• Temperature Compensation – Automatically adjusts charging based on ambient temperature to prevent over or under-charging.
• Low-Voltage Recovery – Recovers deeply discharged batteries, even down to zero volts with Force Mode.

Smarter Battery Charging

The Genius 2X4 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 connectivity.
