Balmar SG210 Battery Monitor Kit with Display

Description

The Balmar SG210 Battery Monitor Kit provides a color-display monitoring platform that learns battery behavior and presents the critical information needed to understand charge condition, battery performance, and remaining energy. It is designed as an intelligent, self-calibrating system rather than a simple voltmeter, helping boat owners make better decisions about charging and onboard power use.

The SG210 supports common battery chemistries and system voltages, allowing it to be used across a wide range of marine battery-bank configurations. Its self-calibrating architecture is designed to improve measurement accuracy without requiring the user to continually correct accumulated amp-hour counting errors manually.

A large, bright color display makes system information easier to read at a glance, while the expandable architecture allows the monitoring system to grow with the vessel’s electrical system. The package includes the display, shunt, and gateway, providing the major components needed to measure current and communicate battery information to the user interface.

For cruising boats, RVs, and other battery-dependent systems where knowing battery condition is more important than simply seeing voltage, the SG210 provides a more complete view of the energy system. It is particularly useful for owners managing larger house banks, multiple charging sources, or batteries where state of charge cannot be judged reliably from voltage alone.
