dual battery setup?

**Txtruckerpaul** · 12-21-2013, 02:21 PM

howdy all,
I'm looking to add a dual battery setup on my 240z talari. I have the big red selector switch so far, but nothing else. Do I need to use a battery isolator on this? I havent installed anything yet and I want to do this right. I feel safer running two batteries in case one dies while I'm in the middle of the lake, plus I have a 7.4 engine that I'm sure has a heck of a current draw when starting up. Has anyone upgraded to dual batteries that can give me some pointers on doing this the right way?

Thanks,
Paul

Lots of threads on this paul if you do a search.
You don't have to use a isolator but it sure is handy and advisable.

Here is a kit from Blue Seas.

I have a new on in the box if you are interested in that particular model.

Absolutely worth the money to put in the isolation setup. Much better system than the old 1/2/combine/off switch. Just turn it to on and it takes care of charging both batteries while either running or on a plug in charger. A few years ago, I installed that setup on my shabah and this spring I will be replacing the switch on my Jubilee with the same setup.
