Balmar 44-SG-12/24 Smartgauge Battery Monitor

Smartgauge™ technology is a huge departure from traditional battery monitors. Balmar has done away with the need for an external shunt. The Smartgauge programs easily and can be easily read and understood - even by your most inexperienced crew member.

Installed with just three 18 AWG wires in the average two-bank battery system, the Balmar Smartgauge monitors battery voltage and state of charge directly rather than through the system wiring, so its data is more accurate and more easily updated.

A specially-developed proprietary algorithm and computer modelling protocol are designed into the system to allow the Smartgauge to "learn" the details of your battery banks. The information it delivers remains highly accurate even as your batteries age. You only tell the Smartgage what type of battery you're using. Its software does the rest.

Balmar's Smartgauge Battery Management System provides at-a-glance information, so you can enjoy accurate and reliable updates on the condition of your batteries.

Based on years of experienced engineering and rigorous, independent testing, the Smartgauge delivers dependable data even as your batteries experience extended use and cycling.

Easy to install and just as easy to program, the Smartgauge takes much of the mystery out of battery monitoring; just select the program that matches your battery type, and the Smartgauge automatically configures monitoring to your electrical system.

Because of its proprietary computer modelling and battery testing techniques, the Smartgauge remains accurate without re-synchronization. The bright LED display and simple controls provide an intuitive and understandable user interface.

Smartgauge has low-voltage and low-charge state alarm outputs that can activate audible or visual alerts (buzzers or lamps).

The Smartgauge™ can be used in 12V or 24V DC charging systems.

  • Proven accuracy in independent testing to within 3% over six months of use!
  • Displays battery Voltage and State Of Charge for your House and Auxiliary bank
  • Extremely easy to install and use. Installs in less than 30 minutes
  • Alarms For High And Low Battery Voltage and Low Charge State
  • Bright, easy-to-read LED display
  • Requires no Shunt or complex cabling - just two or three wires required for installation
  • Automatically adjusts for 12 Volt or 24 Volt systems.
  • Works with Standard Flooded, Deep Cycle Flooded, Sealed Maintenance Free, Gel Cell, AGM and Lead Acid Hybrid batteries.
NOTE: Smartgauge does not monitor Lithium Ion batteries.
