This combo pack of a manual battery switch and an Automatic Charging Relay makes for hassle-free boating by ensuring that your engine starting battery is always charged and ready to use.

These two switches work together to automatically combine and charge your engine and house battery banks when charging current is available from your engine, and then automatically separate the batteries when the engine is off — so you can run your 12 volt toys and appliances without worrying about depleting your starting battery by accident.

All you have to do is turn the battery switch "On" when you get on your boat, and "Off" when you leave — leaving you free to focus on enjoying your time on the water. Simple.

• Simplifies battery bank switching and automates charging
Dual Circuit Plus™ Battery Switch (#5511e) isolates engine and house circuits, and but allows combining the batteries for emergency starting

• Supports high output alternators up to 120 amps, isolates electronics during engine cranking, low voltage protection prevents linking a charged battery with a drained one
• Shares the charge between two batteries more efficiently than a battery isolator
• Ignition protected - safe for installation aboard gasoline powered boats
