OptiMate 2 DUO x 2 Bank Bronze series: 5-step 12V / 12.8V 2A sealed battery maintainer

The OptiMate 2 DUO × 2 BANK is a smart dual-bank charger and maintainer that independently takes care of two 12 V batteries simultaneously. Perfect for dual-battery setups in motorcycles, ATVs, off-grid vehicles, or boats, it supports both lead-acid (flooded, AGM, GEL, EFB) and LiFePO₄ (12.8/13.2 V) chemistries.

Each bank delivers a constant 2 A charge with an intelligent 5-step automatic program that adapts to battery type and condition. It handles recovery from low-voltage (starting at 4 V), then progresses through bulk, absorption, optimize, and safe maintenance modes—transitioning seamlessly as needed and reverting to charge if a drain is detected.

Designed for durability, the charger is fully weatherproof (IP54) and rated for use in extreme conditions down to –40 °C. It draws under 0.5 W standby power and includes spark suppression, reverse-polarity protection, and auto-shutoff in the event of a short or disconnection. Setup is simple with two 2 m DC output leads featuring SAE connectors and included battery clips and waterproof quick-connector leads.
