Pro Mariner Battery Isolator 1 Alternator 70 Amp

The Pro Mariner 70 Amp battery isolator (also called a multi-battery isolator or battery charging isolator) lets a single alternator charge more than one battery bank at the same time. It keeps the banks electrically separate, so a discharged house battery can't drain the starter battery. This protects your engine-starting power on boats, RVs and other 12-volt systems.

Key Features:

• Solid-state design that allows current to flow in one direction only, from the alternator to the batteries
• Charges multiple batteries from one alternator without connecting the batteries to each other
• Stops fully charged batteries from discharging into undercharged ones
• Gold-plated terminals for better conductivity and improved charging efficiency
• Waterproof construction with an IP68 rating for harsh marine environments
• Compliant with ABYC E-11, CE, RoHS and Prop 65
• Made for negative ground alternator systems. It is not recommended for self-energizing alternators.

Pro Mariner has more than 30 years of experience designing marine charging systems and galvanic isolation products. This 70 Amp isolator comes in versions for different numbers of batteries, so you can match it to your battery bank setup.
