Balmar has combined recent technology advances to introduce a next generation battery monitor. The SG200 is quite simply the most accurate battery monitor available today.
Balmar has combined the best features of its 1st generation Smartgauge™ with many advantages of a shunt-based amp-hour counting system. Further, we’ve designed a device architecture which facilitates multiple gauges or multiple shunts to be added to the network-allowing the boater to monitor multiple energy storage banks simultaneously from multiple locations.
In addition, the SG200 Color Display is easy to read, configurable and fits any standard 2 1/16″ gauge socket. Now you can determine your battery(s) condition from anywhere on the vessel or vehicle with multiple displays, or simply add the optional Bluetooth® Smartphone App to keep information in your pocket!
