Pro Mariner 11072 Battery Isolator 1 Alternator 2 Battery 70 Amp

The Pro Mariner 11072 is a professional-grade battery isolator designed to manage charging between a single alternator and two separate battery banks. This 70-amp isolator ensures that both batteries receive optimal charging current while preventing voltage drop between batteries when one is being used.

Key Features:

• 70-amp continuous duty rating for reliable performance in demanding marine and RV applications
• Gold-plated terminals provide superior conductivity and corrosion resistance in harsh environments
• High-efficiency design minimizes voltage drop and heat generation during operation
• Allows simultaneous charging of two battery banks from a single alternator source
• Prevents battery drain by isolating batteries when engine is off
• Solid-state construction with no moving parts for maintenance-free operation
• Suitable for 12-volt DC systems in boats, RVs, commercial vehicles, and emergency vehicles

This battery isolator is ideal for applications where you need to maintain separate house and starting batteries, ensuring your starting battery remains charged while allowing deep discharge of auxiliary batteries. The rugged construction and marine-grade components make it perfect for saltwater and freshwater marine installations, as well as recreational vehicle electrical systems.
