With a 97 percent accuracy rate between two cycles, the Balmar SG200 battery monitor checks the box for precision. Unlike humans, this self-­calibrating unit doesn’t lose accuracy with age, and its internal intelligence allows it to learn and display critical parameters, such as state of charge, state of health, current flow, time remaining, history, faults and alerts. An optional Bluetooth smartphone app is available for on-the-go observation.
