Blue Sea Systems 360 Panel Add-A-Battery Battery Management Panel, 12V, M-ACR, M-Series Battery Switch

Overview

The Blue Sea Systems 1494 is a 360 Panel Add-A-Battery setup for 12V boats that use separate start and house battery banks. It combines an M-ACR 7601 automatic charging relay with an M-Series 6011 battery switch on one panel, giving you a compact way to manage battery isolation, charging behavior, and emergency cross-connect from a single mounting point.

This panel is built for installations where space matters but clean battery management still matters just as much. With overall dimensions of 7.75 x 4.88 x 3.25 inches, it fits well in helm consoles, electrical lockers, and other tight mounting areas where a larger battery management panel may be harder to place.

On board, it suits boats running one battery for engine starting and one for house loads such as electronics, lights, pumps, and accessories. It is a practical fit for refits and new installs where you want a simple 12V battery setup that keeps cranking loads separate from the house side while still allowing manual combine capability when needed.

Key features

• 12V battery management panel for start and house battery bank setups
• Built around an M-ACR 7601 automatic charging relay and an M-Series 6011 battery switch
• Keeps the start circuit isolated from the house circuit during normal use
• Allows emergency cross-connect between battery banks when extra starting support is needed
• Helps protect onboard electronics from voltage sags and spikes during engine cranking
• Compact 7.75 x 4.88 x 3.25 inch footprint for installations with limited panel space

Installation and setup

This panel makes sense when you want switching and charging control grouped in one place instead of mounting separate parts around the boat. Before ordering, check the face cutout area as well as the 3.25 inch depth behind the mounting surface, and leave enough room for cable routing and bend radius at the rear terminals.

Because it is a 12V panel, it fits best in boats built around a two-bank 12V battery system. It works well in smaller cruisers, fishing boats, center consoles, and similar layouts where the owner wants a clear split between engine starting power and house loads without moving to a larger distribution panel.

Compatibility and fit

This unit is for boaters who want straightforward control of a start battery and a house battery in one compact panel. It is especially useful where sensitive electronics share the boat with engine starting loads and you want a cleaner way to manage that separation at the panel instead of relying on loose individual components.

If your boat runs a different system voltage or a battery layout beyond a basic start and house arrangement, confirm the rest of the system matches this panel before installation. The main fit points to verify are 12V system use, available mounting depth, and space for the battery cable terminations behind the panel.
