Battery Monitor
Bat Mon KIT12-48V Gatewa/Smart
Balmar has combined recent technology advances to introduce a next generation battery monitor. Combining 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.
