8.2.1 Battery use and distribution
General points
The boat is equipped with a direct current electrical system.
The boat's electrical system comprises service batteries and the engine battery or batteries. The service batteries serve as the power supply for all the boat's electrical
components. The "engine" battery is used only for powering the electric starter of the propulsion engine.
The boat may also be equipped with:
- a generator powered by its own battery.
the batteries are charged either by a load distributor or:
- by the alternator linked to the engine when the engine is running,
- by the battery charger (where installed).
It is essential that a professional engineer connects the batteries when the boat is first launched.
Always check the condition of the batteries and charge system before putting to sea.
The battery banks are isolated from one another by a charge divider (see below).
