Samlex 160A Automatic Charge Isolator - 12V or 24V

The Samlex 160A Automatic Charge Isolator is an essential tool for effective dual-battery management, particularly for serious boaters and anglers who rely on consistent power. This isolator is designed for use with 12V or 24V systems, ensuring that your primary engine battery and auxiliary battery bank are managed efficiently. Whether you are operating a trolling motor, fish finder, GPS, or cabin electronics, this device helps maintain your starting power while allowing accessory systems to draw from a dedicated reserve.

Built to withstand both freshwater and saltwater environments, the Samlex isolator employs solenoid relay technology to automatically manage battery charging. It intelligently connects or disconnects the auxiliary battery based on the charging voltage from your alternator. When the engine is running and the primary battery reaches the appropriate charge voltage, the isolator closes the relay to allow simultaneous charging of both batteries. An internal disconnect feature prevents the auxiliary battery from draining back into the starter circuit when the engine is off, safeguarding your engine's cranking capacity.

This compact isolator, measuring just 4 x 3 x 6 inches and weighing only 1.1 pounds, is easy to install in engine compartments or battery boxes. It is particularly beneficial for fishing boats, cruisers, and work vessels where reliable battery management is crucial. With its fully automatic operation requiring no user input, the Samlex 160A is the go-to choice for anyone needing dependable power management on the water.
