Separate batteries

Safe to set off… One safety aspect on board is to always be able to start your engine. You must always be able to take shelter from storms or to move out of the way of a ferry.

Separating a battery with a separator relay is a good way to ensure that the starter battery does not discharge. To minimise the risk of failure of the coupling above, there is no mechanics between the starter battery and the starter motor.

However, as the size of the battery bank approaches 400 Ah, there comes a point where the batteries must be so discharged that they become damaged before they start to have difficulty starting an engine. At that point, it becomes more important to adequately monitor the battery bank than to isolate a battery.
