Battery Isolators

Maximize electrical system reliability with battery isolators from Waytek. These essential components are designed to prevent battery drain when multiple battery banks are in use, ensuring dependable performance in vehicles, marine vessels, heavy equipment, and other multi-battery systems. 

Battery isolators function like electrical “check valves,” allowing current to flow from the alternator to the batteries—never in reverse. This ensures your primary battery stays fully charged while auxiliary batteries power accessories like lighting, winches, or communication systems. Waytek offers a wide range of solid-state and smart battery isolators that meet or exceed OEM specs for automotive, marine, commercial, and off-road applications. 

From diode-style isolators to intelligent voltage-sensing models, our selection includes the trusted brands Eaton Sure Power and Cole Hersee by Littelfuse. Whether you're retrofitting a recreational vehicle or engineering a new piece of heavy machinery, Waytek has the battery isolation solution to match.
