ProMariner Battery Isolators

ProMariner battery isolators are used to ensure that electricity is flowing in one direction only. They are installed between the alternator of the boat and the battery. They are a vital tool for boaters who are using multiple alternators for maximum amperage output. Jet and speed boats are the primary models that require multiple alternators. The amount of combustion and spark generated by speed boats must include battery isolators that keep electrical power flowing in one direction. The ProMariner guarantees the isolator can handle such a strong electrical current. For boaters who are running three alternators, 3 bank isolators are also available.
