Remote Battery Switches
A Remote Battery Switch (RBS) is a 500A relay and remote
control switch connected by small gauge single wire. High
amperage switching is achieved with the relay mounted next to the
batteries and controlled either manually by a switch on the remote
battery switch or by the remote switch mounted in an accessible
location. Read the TECH Tip, “Solenoid and Remote Battery Switch
RBS Explained” on page 23.
The installed cost of a remote battery compared to manual battery
switch may not be that different. The cost savings from eliminating
long runs of expensive large gauge battery cables and replacing
them with light gauge control wires can often offset the cost of a
remote battery switch.

Maretron System
Blue Sea Systems’ popular family of ML High Amperage Remote
Battery Switches (ML-RBS) now integrate with the Maretron’s NMEA
2000 Network. This integration allows control and status monitoring
of a vessel’s battery and other high amperage DC switching from
anywhere on the boat where a Maretron display is present. Visit www.
bluesea.com for more information.
Basic System
This basic system allows the Blue Seas Systems Remote Battery
Switch (7700 or 7702) to be monitored and controlled over an NMEA
2000 network using Maretron’s 3.5” color display. The state of the
battery (On or Off) is indicated on the display and the battery switch
can be turned On or Off from the display.
Intermediate System
This intermediate system allows the Blue Seas Systems Remote
Battery Switch (7700 or 7702) to be monitored and controlled over
an NMEA 2000 network using Maretron’s 3.5” color display. The state
of the battery (On or Off) is indicated on the display and the battery
switch can be turned On or Off from the display. In addition, the
Ethernet gateway and WiFi/Router allow a Smartphone or tablet device
running N2KView® Mobile to monitor and control the battery switch.
Comprehensive System
This comprehensive system allows the Blue Seas Systems Remote
Battery Switch (7700 or 7702) to be monitored and controlled over
an NMEA 2000 network using Maretron’s 8” touchscreen display
(TSM800C). The state of the battery (On or Off) is indicated on the
display and the battery switch can be turned On or Off from the
display. In addition, the Ethernet gateway and WiFi/Router allow a
Smartphone or tablet device running N2KView® Mobile to monitor
and control the battery switch.
