The battery separator is used to separate the DC bus into several branches (isolators) and only allows current to flow in one direction in each branch. It supports simultaneous charging of more than one battery from an alternator or other power supply without connecting the batteries in parallel.
Onboard systems often consist of two or more batteries and operate independently when powering 12- or 24-volt power supplies. As mentioned before, batteries need to be charged independently so they have reliable battery isolators or battery combinations. Charge Mate to connect and / or disconnect two batteries. These batteries require independent charging with reliable battery insulators or battery combiners. Charge Mate to connect and / or disconnect two batteries.
