The Seakeeper<\/span> 1 has voltage and state of charge (SoC) based battery monitoring logic to accommodate traditional battery chemistries and emerging lithium-ion technology. The default mode is a low voltage protection system using 11.1 VDC as the protection threshold for flooded and absorbed glass mat (AGM) batteries. SOC-based monitoring is enabled when an NMEA 2000 compatible battery monitoring system (BMS) is broadcasting SOC (PGN: 127506, DC Detailed Status) over the NMEA 2000 network and is required for Seakeeper<\/span> operation with Lithium batteries. The default voltage-based protection is not compatible with lithium batteries due to the discharge characteristics of this battery type.<\/p>\n\n\n

If powered by a lithium battery, the Seakeeper<\/span> and BMS must be connected to a shared NMEA 2000 network to prevent excessive battery bank discharge. An external BMS with a shunt can be used in place of an NMEA 2000 SOC signal. However, the Seakeeper<\/span> will not provide any battery monitoring functionality. The following guide will explain the functionality of the user interface and menus.\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n\n\n\n

  1. To access the battery monitoring configuration manager, press and hold the battery icon on the Home screen until the Battery Monitoring Configuration pop-up appears.<\/li>\n<\/ol>\n\n\n

    1. The Battery Monitoring Configuration will automatically initiate a pop-up window after detecting the SoC signal. You can open the configuration menu from this pop-up window by pressing the Continue button.<\/li>\n<\/ol>\n\n\n

        • Battery SOC<\/em><\/strong>\u2014This option allows the user interface to monitor the NMEA2000 network for the battery state of charge (required if lithium batteries are used to power the Seakeeper<\/span><\/span>). When selected, the Cut-off threshold slider will determine at what battery charge the Seakeeper<\/span><\/span> begins powering back to conserve battery power.<\/li>\n\n\n\n
        • No Selection<\/em><\/strong>\u2014This is the configuration manager’s default setting. Low voltage protection at 11.1 VDC is the manager’s default setting unless a different option is selected.<\/li>\n\n\n\n
        • Use voltage monitoring<\/em><\/strong>\u2014<\/em>This disables SoC logic and uses actual battery voltage to initiate lowering the power drawn by the Seakeeper<\/span><\/span> when the battery voltage drops to 11.1 VDC on Seakeeper<\/span><\/span> 1.<\/li>\n<\/ul>\n\n\n\n

          The Cut-off Threshold Slider<\/strong> controls the level of charge at which the Seakeeper<\/span> will begin lowering the power it draws. The default setting is 20% charge, and the slider allows the selection between a 10% and 30% charge state.<\/p>\n\n\n\n
