Pro Mariner 11132 Battery Isolator 1 Alternator 2 Battery 130 Amp

The Pro Mariner 11132 is a heavy-duty battery isolator designed to manage charging between two separate battery banks from a single 130-amp alternator. This isolator ensures that your starting battery remains charged while simultaneously maintaining your auxiliary battery bank, preventing the common problem of a dead starting battery after using house loads.

Key Features:

• 130 amp continuous duty rating for high-output alternator systems
• Gold-plated terminals for superior conductivity and corrosion resistance
• Diode-based isolation prevents battery drain between banks
• Automatic charging distribution to both battery banks
• Enhanced thermal efficiency design for reliable operation
• Prevents discharge from one battery to another when engine is off
• Ideal for marine, RV, and commercial vehicle dual battery systems

This battery isolator uses solid-state diode technology to automatically direct charging current from your alternator to both battery banks while keeping them electrically isolated. The heavy-duty construction with gold-plated terminals ensures long-lasting performance in harsh marine and automotive environments. Perfect for boats, RVs, work trucks, and emergency vehicles requiring reliable dual battery management.
