Battery Isolators

Battery Isolators for Large Trucks, Airplanes, Boats, and Utility Vehicles at Del City

Vehicles like large trucks, airplanes, boats, and utility vehicles typically rely on two or more batteries that function independently to power 12V or 24V systems. To ensure these batteries are properly charged and operate independently, battery isolators or battery combiners are essential. The primary function of a battery isolator is to prevent the failure of a single battery from incapacitating the entire electrical system. It separates multiple batteries, ensuring that if one battery fails, the others remain operational, providing a crucial backup power source.

Battery isolators also help prevent a vehicle's electrical system from drawing power from multiple batteries simultaneously, which could quickly drain all batteries and cause system failure. This is especially important in high-demand applications like marine, aviation, and utility vehicles, where reliable power is critical.

At Del City, we offer top-quality battery isolators from trusted brands like ProMariner (available in 40 AMP and 90 AMP models) and Mastervolt (available in 70 AMP and 130 AMP models) to meet your onboard electrical needs. These isolators provide dependable, independent charging solutions to keep your vehicles' electrical systems running smoothly and efficiently.
