Sound Good?

 

sounds good to me.

go for it!

 

i had marine battery for two years. no problems at all, after i realized that i have deep cycle marine battery i changed it, and no difference...

 

I personally think optima's are way overrated. I always go diehard.

 

i wanted braille but it was too much

 

Doesn't braille only make the small carbon ones? (I'd look it up but the majority of the net's blocked at work)

Those are basically enough to power up the car & that's it. Try runnin a system on it & it's done after like 3 mins, haha.

 

So I have a few more questions.

I have the big 3 (ground, chassis and alternator), and my question is: Lets say I get a Odyssey 680(is that good enough) with the optima, and then. I just connect the original stock positive wiring to the odyssey, and then just put the big 3 alternator on the optima, shouldn't they both charge and I wouldn't need a isolator or whatever?

 

Bump for an answer!

 

^^^ from what I've always seen in the last decade, you still need an isolator so your extra battery doesn't get drained...

 

Already answered...here and in several other recent threads.
