Marine Battery Isolator

The battery isolator is very similiar to the battery switch in that it can charge two batteries and yet isolate the two.The difference being that there is no manual switch to operate using the battery isolator, its all automatic. There is pros and cons to both setups, with the battery isolator you have only one battery for the engine and one auxiliary battery for normally cabin use. Both batteries are charged by the engine and when one battery is discharged it will not drain the other. An isolator is basically a diode, a one way path through a circuit. There are different setups as with the battery switch such as dual engine installations and isolators that will charge more than two batteries. The battery switch can be manually switched between batteries to charge or start off from one or both batteries, where the isolator cannot.
