wiring a second battery w/ relay

[KenC210]

Ok so i have picked up a yellow top, got it new for $50. so temporary till i get the xs power, and i am going to wire it in the cargo of my ford escape. I was looking at This relay >>> http://www.sonicelectronix.com/item_28365_The-Install-Bay-IB500.html and think it would fit my needs. My main battery is a diehard gold http://www.sears.com/shc/s/p_10153_12605_02850640000P I do have the big 3 upgraded. A h/o alt will be ordered soon just saving up for it. I am wondering is it a good or bad idea to use the relay? If not what options do i have for wiring the second battery up.

just wire the batts in parallel, no need for a isolator.

so pos to pos on the battery w/ fuse in between each battery. I have searched this before and some people say it is bad on the batteries, although the diehard is maybe just at 2 months and the yellow top is new. So i am just curious will it be bad on the batteries. Also i dont plan on running with the car off anyway.

wont be bad on the batteries, just pos to pos fused, and neg to neg, or you can ground in the back to the frame

thats how i have my batts wired had it like that for months with no problems i think most new batteries are compatible with each other as long as they are all 12v back in the day i think something was different inside or something that made them leak if used together

Thank you for the quick responses... also what should i fuse the batteries with? 300a or should i use lower? I have three amps i am running 2 zx1000.1 and zx650.4. Also i have a cap a 6 farad i am not using would i benefit from using it or should i just leave in the closet.

Fuse for the wire size so if its ofc 1/0 then 300 amp fuse. Forgot to say fuse the wire twice once after the front battery and the other before the back battery.
