Advanced Battery Monitor System

Accurate & Dependable

Smartgauge™ is changing how sailors and power boaters think about battery monitors.

Balmar 7-Series Alternator

Balmar's new Smartgauge™ Battery Monitor provides highly accurate monitoring at a similar cost of standard ampere hour counting monitors. The easy-to-understand display, dependable State-of-Charge Percent (SoC%) reading and its ease-of-use mean that even the most technically challenged crew member can understand just how much power is left in the battery.

Ease of Use: Just select your battery type at setup and Smartgauge™ does the rest! Smartgauge™automatically adjusts for 12V or 24V operation.

Accuracy: Smartgauge™ is proven in independent testing by Enersys® to be accurate within 3% after 6 months of use. Smartgauge™ automatically adjusts for temperature conditions and the battery's health.
