Battery Isolator

[d18]

I was looking for a battery isolator, and came upon
this product. Does anyone have any insight on this?

Are they any good?

I have a mid 1980's 50 Merc...

While I am not familiar with that exact product, what they are calling a combiner is simply a "charge relay".

I run a Blue Seas ACR (automatic charging relay) that is basically the same thing.

They provide "isolation" when starting so you don't suck power from your "house" batteries (and vice versa), but allow the motor to charge both your battery banks.

For it to truely be a combiner you need to add a selection switch into the mix, that would allow you to "manually" access "all your power" should your starting battery ever die on you.
