How It Works

The BM-1 LI Battery Monitor provides a clear and intuitive display of your marine battery’s vital statistics, including voltage, charge/discharge current, state of charge, and remaining time to charge or discharge. It alerts you when the battery charge drops below a safe level, allowing you to shed loads or initiate charging to protect your investment.

Featuring a resettable Amp Hour counter, the monitor helps you assess the efficiency of your charging system and track power consumption patterns, ensuring optimal battery management. Additionally, a second input allows you to monitor the engine's starter battery voltage separately.

The BM-1 LI employs advanced algorithms, integrating amp-hours over charge and discharge cycles and utilizing an adaptive internal mathematical battery model. This dual-algorithm approach ensures continuous performance updates, eliminating the need for manual synchronization and maintaining accuracy across varying load currents through the inclusion of Peukert's equation.

Despite its sophisticated features, the BM-1 LI maintains a low power draw of just 1.5 milliamps, making it an energy-efficient addition to your marine setup. Its easy installation process and comprehensive monitoring capabilities make it an excellent value for boaters seeking reliable battery management.
