It is for my RR.

I don't have a wall behind the seat, but I'd really like the box to prevent the battery from being hit by anything in the trunk. I'm going to skip the NHRA requirement and leave the trunk switch out.

I'm honestly not sold on the Red Top. I researched last night, and I'm convinced to buy a premium parts house AGM battery over the Red Top.

I've been running Die Hard(I believe it is) in my
race car and in my Rampage.. the one in the race car
has been in there for YEARS.. never even had a charger
on it... we did some testing on the Optima batteries
at Chrysler(the battery lab did) to see if we would
go with them in production... they werent that great
and didnt go with them... also being that I run a
alt on all my junk I use the standard auto battery
and not the marine ones.. they have a different way
of being used(without a alt)
