The high amperage combiner is a good choice that
allows the use of heavy cable.

It's better than the standard Hella dual battery
relay system.

I would like to point out that the 1315 costs
twice as much as the 4-way boat switch or Hella
relay kit, if your budget is a consideration.

As Mike has pointed out, the 1315 really is a
neat item to have if you can afford it.

So add affordablity to my list of pros for the
boat switch .
I get a lot of my needed stuff at junkyards- that
would be a cool to find a 1315 in a wrecked
conversion van or RV.
