## Overview

The BEP 720-MDO is a remote-operated 500 Amp battery switch designed for marine applications, supporting 12/24V systems with an advanced optical sensor for remote control. It reduces cable length and weight by mounting close to the battery, saving installation time and costs. With LED status indicators, manual override, and compatibility with multiple voltages, it’s engineered for reliable, flexible, and efficient power management on modern boats.

## Description

The MD range of battery switches allow you to install the battery switch very close to the battery, to remotely manage the increased electrical loads found on today's boats. This reduces cable lengths and sizes, providing significant savings in expense and weight of copper battery cable. They are ideal for remote isolation of bow and stern thrusters. The 720-MDO has been enhanced to offer easy standard installation, or advanced options capable of switching different voltage circuits from the main supply (for example: a 48 volt bow thruster with a 24 volt house supply). The optical sensor uses the same easy connection for standard installation and gives you the ability to control different voltage circuits such as 36 or 48 volts. It can be used to switch positive or negative lines and the main contacts can be isolated from the control circuit allowing operation via another battery source. This optical sensor also has low stand-by current draw (<5mA).

Review: Worked as described - Mounted, wired #8 Eire from derp cycle fuse to power posts (only using about 30 amps), connected remote wire activator and tested. Has been in service short time so will report if issue shows up.
Review: missing Parts, open box, - These are all open torn taped up boxes and mine is missing the specialized screws that mount the switch to the base, by the time I went to install it and found out the screws were missing it was past the return date, so i cannot resolve

## Features

- Remote operation
- Battery switch can be mounted alongside battery, reducing cable lengths and cable sizes. (Large cost and weight saving in copper cables)
- Reduced installation labor due to shorter battery cable runs
- Manual override option to meet CE/ABYC requirements
- LED status identification for remote control switch. Same capacities/specifications and mounting options as standard BEP battery switches
