BEP 701S Mini Battery Switch 1-2-BOTH-OFF 300 Amps Max

The BEP 701S Mini Battery Switch 1-2-BOTH-OFF 300 Amps Max is purpose-built for boaters and anglers who demand reliable dual-battery management in a compact footprint. Whether you're running electronics, trolling motors, and auxiliary systems on a multi-day offshore trip or managing house and engine batteries on a center console, this selector switch gives you precise control over which battery bank powers critical systems. Designed by BEP Marine—a leader in marine electrical solutions—the 701S delivers the switching functionality of full-size alternatives without consuming valuable console or helm real estate.

The 701S features a 1-2-BOTH-OFF configuration, allowing you to isolate battery 1, battery 2, connect both banks in parallel, or cut power entirely—critical for preventing parasitic draw when the boat sits idle and for switching loads during operation. Rated for 300 amps maximum continuous draw, it handles the demands of modern marine electrical loads: GPS plotters, radar, high-output alternators, and electric trolling motor circuits all operate safely within its specification. The unit's compact housing maintains the same external dimensions as the standard 701 model, and removable side plates and back cover simplify installation in tight helm configurations common on center consoles, bay boats, and sportfishing vessels.

Anglers and cruising boaters benefit most from the 701S when upgrading aging electrical systems or installing secondary battery banks for extended fishing trips, overnight anchoring, or auxiliary power independence. The switch integrates seamlessly with standard marine wiring practices and pairs well with isolator modules for true isolated-battery architecture—the configuration BEP Marine recommends for serious salt-water and extended-use vessels. At just 2 lbs, installation is straightforward for both professional marine electricians and experienced DIY boat owners comfortable with 12V DC systems.
