I run two batteries on my boat hooked up in parallel. For those of you that are also doing that are you using two multipurpose batteries or a combination of deep cycle and starting?
I have my big motor connected to one battery by itself (but that battery is connected to the other). And then have all my other stuff (TM, electronics, bilge, etc.) on the other (but connected).
In this manner does it matter whether one battery is starting or deep cycle or not? Whatever set-up I am using is working but am contemplating getting fresh new batteries and getting some battery boxes to tidy everything up back there.
I noticed in wal marks the other day that you can get 2 ga battery cables for 11 bucks. Right now I am using some lighter gauge wire for connecting the two batteries. I think I will upgrade there as well.
