Product Details

The Balmar SG235 is an award-winning, second-generation battery monitor kit designed for marine and RV applications requiring NMEA 2000 CANbus network integration. This complete monitoring solution connects to your existing N2K network to provide comprehensive, real-time battery data including voltage, state-of-charge (SoC), state-of-health (SoH), time remaining, and current flow.

What's Included:

  • NMEA 2000 certified SmartShunt (SG2-0130) with intelligent shunt-based monitoring
  • NMEA 2000 M12 (DeviceNet) adapter cable for network connectivity
  • Bluetooth gateway (SG2-0300) for wireless smartphone monitoring

Key Features:

  • Intelligent self-calibrating accuracy for precise battery monitoring
  • Learns and displays all critical battery parameters automatically
  • Supports all common battery chemistries including lithium LiFePO4, AGM, flooded, and gel batteries
  • Compatible with 12V to 48V DC systems
  • Free Balmar smartphone app available for iOS and Android devices
  • Feeds battery data directly to NMEA 2000 multifunction displays at the helm
  • Expandable architecture allows multiple SmartShunts for monitoring multiple battery banks

This kit does not include a color display—monitoring is performed via the free Balmar app through Bluetooth connectivity or through existing NMEA 2000 compatible chart plotters and displays. The CAN port (P2) on the SG2-0130 SmartShunt is dedicated for CANbus (NMEA 2000) connections only.
