Balmar 12V-48V Battery Monitor Kit with NMEA 2000, Bluetooth Gateway and Color Display

Comprehensive 12V to 48V Battery Bank Telemetry and Network Integration

Precision Monitoring for Marine, Off-Grid, and Mobile Power Systems

Accurate battery management is the cornerstone of any dependable marine or off-grid electrical system. This second-generation monitoring kit from Balmar delivers real-time, precision telemetry for 12V, 24V, 36V, and 48V DC architectures. Designed for seamless integration into modern vessels and advanced recreational vehicles, this all-in-one package combines local visual readouts, wireless smartphone connectivity, and full NMEA 2000 CANbus network compatibility.

Unlike basic voltage-based gauges that struggle to interpret flat discharge curves, a shunt-based monitoring system actively tracks current flow in and out of your battery bank. This reduces the risk of unexpected power loss, helps prevent premature battery degradation from deep discharging, and eliminates the guesswork often associated with standard factory gauges.

Seamless NMEA 2000 CANbus and Wireless Connectivity

Modern marine and mobile setups demand unified data across multiple helm stations and control panels. With the included NMEA 2000 M12 (DeviceNet) adapter cable, the SmartShunt communicates directly with compatible Multifunction Displays (MFDs) and chartplotters. This allows captains and system operators to view critical battery parameters right alongside navigation and engine data without needing to run separate proprietary display networks across the entire vessel.

For diagnostics and monitoring away from the main helm or control panel, the supplied Bluetooth Gateway enables wireless access via the free Balmar App (available on iOS and Android devices). Whether you are inspecting the battery compartment or relaxing in the cabin, you can check system status directly from your mobile device.

Key Features and Kit Inclusions

• Multi-Voltage Compatibility: Supports 12V to 48V DC battery banks.
• Dedicated Colour Display: Provides high-contrast, at-a-glance system status at your main electrical panel or helm.
• NMEA 2000 SmartShunt: Delivers accurate current and voltage sensing with direct CANbus data translation.
• NMEA 2000 M12 (DeviceNet) Adapter Cable: Connects the SmartShunt to an existing NMEA 2000 backbone.
• Bluetooth Gateway: Enables wireless monitoring via the free Balmar app, available from the Apple Store and Google Play.
• 10m SmartLink Communications Cable: Offers ample length for flexible routing through bulkheads, conduits, and complex vehicle layouts.

Engineered to Reduce Installation Complexity

Sourcing individual adapters, shunts, and communication gateways separately often leads to compatibility issues and installation delays. By supplying the colour display, NMEA 2000 SmartShunt, DeviceNet adapter, Bluetooth module, and a generous 10m SmartLink cable in one cohesive package, Balmar simplifies the upgrade process. Supplying the core components together saves installation time for marine electricians and DIY system builders alike.

Upgrade Your Power Visibility
