Balmar Bluetooth Gateway f/SG200

The Balmar Bluetooth Gateway f/SG200 is a wireless connectivity module designed for boaters and marine system operators who demand real-time monitoring and control from their smartphone or tablet. This optional 39-inch gateway bridges your Balmar SG200 battery monitor to your mobile device, eliminating the need for hardwired display panels in the cabin or helm station. Whether you're managing a cruising sailboat, center console, or coastal trawler, wireless access to critical charging data transforms how you monitor your electrical system while underway or at anchor.

This compact gateway (measuring 4 x 10 inches and weighing just 0.15 lbs) uses Bluetooth wireless technology to transmit battery state-of-charge, voltage, current, and system diagnostics directly to your mobile app. The extended 39-inch cable allows flexible installation behind panels, under dashboards, or within engine compartments, while maintaining a strong wireless signal throughout your vessel. The modular design integrates seamlessly with existing Balmar SG200 monitor systems without requiring replacement of core charging or monitoring hardware, making it an ideal retrofit for older installations seeking modern smartphone integration.

Cruising sailors, liveaboards, and power boaters benefit most from this gateway when operating in remote anchorages where battery health oversight is critical to comfort and safety. The wireless app interface works across multiple crew members' phones, allowing anyone on deck or below to check voltage trends, charging status, and load consumption without visiting the electrical panel. Installation pairs directly with your existing SG200 unit; contact Balmar directly for technical support or warranty claims, as this product does not accept returns through standard retail channels.
