Increasingly complex onboard electrical systems designed to support the latest navigational, weather, communication and entertainment devices require a strong and steady supply of DC current.
The new Vision 4 Battery Monitor from Scandvik Marine has a digital filter to block out false readings that can be caused by engine startup, fuse faults, unballasting and other anomalies, according to the company. It is designed to provide precise indications of voltage and charge status on up to four battery banks. A non-volatile memory retains configuration data if power is lost or interrupted. During a charge, the battery monitor factors in output that diminishes according to a battery’s charge. During discharge, it considers restored capacity that diminishes according to the draw, the company said. It has a cycle counter (charge/discharge) that helps with determining battery life. The Vision 4 also automatically detects float mode, so readings aren’t affected by each successive charge/discharge cycle. The unit retails for about $530.
