Battery move PC925 in a Z27ag

Finally after 4 years my big ass stock battery died...It’s a huge mfarker...Size of a 4wd battery I reckon.
It weighs in at 16kg and the one I replaced it with is an Odyssey PC925 weighing in at 11.4kg.
I picked this battery for no apparent reason. It is a rip off in Australia at 370AU.
But I picked it to try an experiment. I wanted to stick it under my seat.

And get some more room in my engine bay without losing room in the boot with a battery box.
I had some timber which my car amp was attached to. I pulled the amp out because I have no more sub @_@

Originally I was going to cut a tight square in the wood to slide the battery into it.





But to my surprise it sits perfectly on top of the wood and still has about 15mm gap between the terminal and the chair...
Best luck I had in awhile.

From memory the timber is simple 16mm MDF which I cut to size. It sits between the 4 chair mounting posts.

A tied down strap was my safety to guarantee no movements at all.



I used L brackets to hold the board in place to two of the opposing chair mounting points.
I have a ground cable which I drilled into the chassis I also ran a 2nd cable to the chassis ground point.

Apart from that I used some Super Cheap battery terminals and re used my amp cable to run to the cars positive terminal.

I am yet to put a kill switch in for the battery and tidy up the engine bay terminals.
