Pro Mariner Battery Isolator 2 Alternator 70 Amp

The Pro Mariner 2 Alternator 70 Amp battery isolator (also called a multi-battery isolator or dual alternator battery isolator) charges more than one battery bank from two alternators. The batteries never have to be connected to each other. It suits marine, RV and automotive electrical systems. It also helps keep the starter battery from being fully discharged by accessory loads.

Key Features:

• 70 amp maximum current rating
• Takes input from two alternators and charges multiple separate batteries at once
• Solid-state, diode-based design that lets current flow in one direction only. This stops a fully charged battery from discharging into a weaker one.
• Gold-plated terminals for better conductivity and efficiency
• Waterproof, corrosion-resistant construction for harsh environments
• No ground wire required
• Insulator boots on each terminal help prevent short circuits
• Improved heat sink design
• Complies with ROHS, CE, Prop 65 and ABYC E-11

Installation Notes: This isolator is designed for negative ground alternator systems. It is not recommended for self-energizing alternators. Mount it in a well-ventilated location as close to the alternator as possible. Do not mount it on the engine or near an exhaust manifold.

This line is available in configurations for different numbers of batteries. It gives boat owners, RV owners and vehicle owners a simple, dependable way to run dual-alternator, multi-battery charging.
