Image of : Balmar SmartLink Battery Monitor Kit - SG200 Balmar SmartLink Battery Monitor Kit - SG200 Item # 861645


The Balmar SmartLink Battery Monitor Kit (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, Balmar designed a device architecture with the option of multiple displays or multiple SmartShunts to be daisy chained 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!
