The smartest switch for two batteries

A great solution to an age-old boating problem. This complete battery switch system automatically selects which of your batteries charge while you are underway - and which get tapped when you play!

Smart charging on the run - automatically.

The heart of this ready-to-install battery switch kit is a clever relay that automatically combines your starting and trolling/house batteries - so both are being charged - whenever sufficient voltage is available.

Conserve your cranking power - automatically.

Then, as you use power, whether running trolling motors, stereo, anchor lights, or other accessories, the same relay that conected your batteries for charging now unlinks them so you are only draining one - leaving the other with the starting power you'll need later. This switch is similar to a Perko Battery Switch with many more battery switch features.

Manual battery switch means fewer dead batteries

Eliminate those "mysterious" drains in your boat wiring that can cause dead batteries while you're not using your boat. The included battery switch allows you to easily shut off your boat's power when you're away.
