Battery Isolators for Multiple Batteries

Battery Isolators eliminate multi-battery drain when two or more battery banks are in a charging system. These act as a check valve between the batteries and the alternator, allowing current to only flow in one direction, from the alternator to the batteries. Quality and reliability are the cornerstone of our battery isolator selection, featuring leading manufacturers such as Cooper Bussmann Sure Power and Cole Hersee.

Need a battery isolator for automotive, equipment or marine applications? Waytek offers a variety of solid state models, all designed to meet or exceed OEM specifications. Want a battery isolator with "brains"? Waytek also carries a selection of smart battery isolators, which are smaller, lighter, more flexible and generate less heat than traditional models.
