The 40SI durable brushless model, in 240, 275, 300, and 320 Amps, provides the highest efficiency rating in the industry today. High efficiency translates to less engine horsepower requirements, resulting in substantial fuel savings. It comes with remote sense technology as standard.
Remote Sense provides highly accurate voltage readings and optimizes battery state-of-charge resulting in improved efficiency and overall battery life. It maintains 14 volts at the battery by increasing charging voltage at the alternator to compensate for voltage drops. Remote Sense Technology Improves Battery Charge Time by 50% and Can Decrease Battery Warranty Claims by 30%
