Abstract: A multi-bank marine battery charger having at least one 12 Vdc charging bank and at least one multi-voltage 24/36 Vdc charging bank, and a method of operating such multi-voltage charging bank, are provided. The method enables the multi-voltage charging bank to, one or more, turn on a fully depleted battery, determine the voltage class of the connected battery, fully charge, and detect completion of the charging of a single 24 or 36 Vdc battery.

Abstract: Methods of situationally controlling marine devices connected via a one boat network on a watercraft are presented. The marine devices are selected from fishfinders or other OBN devices, trolling motors, heading sensors, main propulsion engine, i-Pilot Link, shallow water anchors, AIS/MARPA, smart chargers or power monitors, downriggers, trim tabs, drift paddles, lighting, sonar and imaging transducers, chart plotters, foot pedals, handheld remote controls, and mobile marine apps. The method includes the steps of identifying at least one situational condition of at least one first marine device, identifying at least one second marine device, and triggering a situational control action for the at least one second marine device when the at least one situational condition for the at least one first marine device is met. The methods include situationally controlling a speed of a trolling motor and anchoring of the watercraft, as well as providing advanced power management thereon.
