Batteries & Charging System

Nike IV has three separate banks of batteries - all new.

Engine Batteries  
Which consist of one bank with two maintenance free batteries SeaVolt with total capacity of  220 Ah. This batteries are dedicated only for running main engine and its instruments and accessories like separate fuel pump and fuel level measurement. They are charged by main engine Hitachi 80A alternator, but could be charged as well by diesel generator just by turning a selector switch on. In a case of emergency, the power of this batteries could be enhanced by connection with running batteries (bank A, bank B, or both) just using a selector battery switch. The boat comes with spare new Hitachi 80A alternator.

Working Batteries

The Batteries could be charged by Kubota Diesel Generator, by main engine alternator or at the shore by Hearth Inverter/Charger. Each bank could be charged separately or together.

The negative terminals are connected together. The positive terminals are secured by fuses and are connected to Batteries selector switches. There is one extra connection ready for use with wind-water-additional alternator-or-solar charging system.

Battery Switches 
Number of selector switches allows different combination for charging as well as for using them. Any bank could be used for running electronics and at the same time the other bank could run SSB Radio, Autopilot, Refrigerator and vice versa. Voltmeters and Ammeters give you full control over theirs status.
