Balmar SG200 Battery Monitor Kit, 10-Meter Cable

The Balmar SG200 Battery Monitor Kit is an expandable 12-48V system with a 10-meter cable, combining SmartGauge learning with shunt-based amp-hour counting.

Using both methods together is what makes the reading trustworthy, because each one fails differently on its own. Amp-hour counting drifts as a bank's real capacity falls with age. SmartGauge learning tracks the battery's actual behavior. Combining them corrects the drift without losing the precision of counting.

It supports lead-acid, lithium iron phosphate, standard AGM, TPPL AGM, carbon-foam AGM and gel. That range matters because each chemistry behaves differently as it discharges, and a monitor assuming lead-acid behavior will misread a lithium bank badly.

State of charge, state of health and time remaining go well beyond what voltage alone can indicate. Voltage on a bank under load tells you almost nothing about how much is left, and a voltmeter alone leads to unpleasant surprises. Explore more alternator parts and accessories.
