Balmar SG200 Battery Monitor

Know the exact state of your boat batteries, at all times

You want to know your battery’s state of charge, state of health, current flow and history? Of course you do—and the Balmar SG200 provides this data with a glance at the standard-size 2-inch gauge. Or for that matter, with a glance at your phone. Thanks to Bluetooth, an optional smartphone gateway, and a free app, you can see all the info right on your smartphone screen. This is a “smart” monitor that learns, autocalibrates and typically provides 97 percent accuracy for multiple battery types in 12- to 48-volt banks.
