BEP Marine

<h3>About BEP Marine</h3><p><strong>BEP Marine</strong> has been a cornerstone of the marine electrical industry since its founding in 1995 in Auckland, New Zealand. Rooted in New Zealand's world-class yachting culture — a scene shaped in no small part by successive America's Cup campaigns — BEP Marine built its reputation on engineering electrical products that could survive the most demanding conditions on the water and beyond. Today, the brand is part of the Navico Group under Brunswick Corporation, and its products are specified as original equipment by leading boat, emergency vehicle, and RV manufacturers worldwide.</p><h3>Engineering for the Harshest Environments</h3><p>What separates BEP Marine from generic electrical suppliers is a relentless focus on real-world performance. Every product in the BEP lineup is designed to meet exacting performance specifications, capable of withstanding prolonged exposure to salt air, moisture, vibration, and extreme temperatures — both at sea and on land. BEP backs this confidence with a &quot;Trusted Quality&quot; 5-year warranty across their product range, a testament to how thoroughly their components are tested before they reach your vessel.</p><p>BEP's engineering culture also prioritizes ease of integration. Whether you're wiring a simple single-battery sailboat or a complex multi-bank power system on a large cruiser, BEP products are designed to slot into both straightforward and comprehensive electrical architectures without hassle. Their innovative product lines — including the CZone digital switching system and the Pro Installer series — represent the cutting edge of onboard power management, allowing boaters to monitor and control circuits from touchscreen interfaces and minimizing valuable space in crowded electrical panels.</p><h3>Core Product Categories</h3><p>BEP Marine's catalog spans the full spectrum of marine power management. At the heart of their offering are <a href="/11486-bep-marine-battery-switch-12204">battery switches</a>, where BEP has pioneered design innovations for decades — from compact On/Off isolation switches to high-capacity selector switches rated at 400A continuous and 600A intermittent. Their award-winning EZ-Mount line (recipient of the prestigious METS DAME award) features an industry-standard footprint that clusters with other Pro Installer components, saving precious onboard space.</p><p>For remote power control and automated charging management, BEP's <a href="/11486-bep-marine-solenoids-202547">solenoids</a> allow boaters to switch high-amperage loads using low-current control circuits — essential for bow thrusters, windlasses, and other high-draw accessories. The Digital Voltage Sensing Relay (DVSR) automates second battery bank charging with exceptional efficiency.</p><p>Rounding out the core lineup, BEP's <a href="/11486-bep-marine-battery-disconnect-switches-200143">battery disconnect switches</a> deliver reliable isolation capability for single or dual battery banks, ensuring your vessel's electrical system can be safely de-energized for maintenance, storage, or emergency situations. Motorized disconnect variants allow remote operation, making them ideal for installations where the battery is difficult to access directly.</p><h3>Who Uses BEP Marine?</h3><p>BEP Marine serves both OEM boat builders and the marine aftermarket, with a product range trusted by recreational boaters, commercial operators, and emergency vehicle fleets across North America, Europe, Asia Pacific, and Oceania. If your application demands reliable, durable, and intelligently designed electrical components, BEP Marine delivers solutions built to go the distance.</p>

Product Details

The BEP Marine 720-MDVSO Dual Operation Voltage Sensitive Switch (VSS) automatically manages dual battery banks by sensing voltage levels and providing optimal charging efficiency. This intelligent battery management system automatically combines or isolates independent battery banks based on the presence of a charging source such as an engine alternator or battery charger, while also offering a remotely activated emergency parallel connection feature.

Key Features:

  • Dual battery sensing technology automatically manages two independent battery banks
  • Remote emergency parallel function via momentary dash button provides 10-minute battery combination for emergency starting
  • Manual override option for complete control
  • Compatible with both 12V and 24V systems (both banks must be same voltage)
  • Heavy-duty 500A continuous rating handles high-current applications
  • Low power consumption of less than 6mA
  • Lowered cut-in voltage (13.3V/26.6V) optimized for low output alternators and high temperature environments
  • Ignition protected for marine safety compliance

Marine-Grade Construction:

Engineered specifically for the harsh marine environment with tinned copper conductors for corrosion resistance, stainless steel hardware, and high-temperature fiber-reinforced plastic housing. The unit features On/Off switching operation and can be installed via recess or surface mounting.

Technical Specifications:

  • Voltage: 12/24V DC
  • Current Rating: 500A continuous
  • Cut-in Voltage: 13.3V (12V) / 26.6V (24V)
  • Power Consumption: Less than 6mA
  • Dimensions: 4" L x 4" W x 4.3" H
  • Mounting: Recess or surface mount

Package Includes:

  • Dual Operation VSS Switch
  • Installation manual

Great easy experience

A very satisfactory experience. The price I paid was the lowest I found on the internet for this product. Ordering was easy, and without hassle. My order was shipped promptly and arrived sooner than I expected. Order date to receipt was only 6 days

good

I need this for tomorrow. Thanks!

Easy to find my product and it came fast thanks for your service

Cheap

it was good

shipping is ridiculous but still cheaper than going to oreillys

Everything is good except for one price that I saw on your page. It is for the Stillen Big Brake kit 30-7050. I got very excited cause it said 183.00 and came to find out it is an error. Would be nice if you guys would follow up on this. Thanks anyways.

It's been very easy so far. Thanks!

Very competitive pricing (within best 2-3 prices I could find anywhere online) on a foam kayak carrier kit. Shipping was a little high relative to competition, but base price was good enough that with this stellar reputation on RR, ordering from them seemed the right way to go. Ordered 2/17, received it on 2/20 - so *excellent* performance on the delivery side. Satisfied with my decision to shop here. Will eagerly consider them again in the future.
