Currently got big build on Rex resprayed purple full mazdaspeed. Going for turbo build, suspension, big brakes tyres. So need space in engine bay.
Looking to put battery in boot. Seeing if anyone disagrees with kit before buy and install. As I’m unsure if the battery tray should be plastic or box type as where would the fault current go. Or am I overthinking. And has the kit got an adequate protective device for full car. My cars is at shop been sprayed just installing minor bits before putting bumpers back on.
I’ve got no experience in welding & fabrication so mine wouldn’t be the best or safe so to say. Off the shelf is best for me. Dimensions size up correctly for the fleabay box for a snug fit. Maybe need bigger threads to secure it down.

I’m able to make them to order if you or anyone else are interested.
They would be of the same design as mine in the photo but can adjust dimensions accordingly to suit your battery size.
It’ll be made of aluminium, it will require etch primer then a top coat. I’m sure you could do that with a rattle can. It would push the price up as I’d have to purchase them.
Was testing my luck Neil Yeah I’m interested but need one soon as possible. I’ll give you a bell in morning. Could be worth a group buy. Box Cables terminations. Coloured conduit. Ect.... Full location kit box same size as exisiting OEM battery tray
Word of warning on running thick cable learned from doing audio installs, in the listing on eBay they just state 300amps 40mm which doesn't say a lot.
Find out what the actual gauge of the internal conductor is and not the dimensions including the sheathing, also if it's pure copper or copper coated aluminium.
4awg copper should do it or 2awg CCA.
Note that the original battery box has a cooling air duct and batteries that are oversized, restricting the airflow, have been known to overheat and bulge the sides - which is the first stage towards meltdown.
You need to provide an airflow within the boot for relocation.
Conventional batteries also give-off hydrogen when they charge, which is another reason to vent the boot space.
I'm not sure Dave. I doubt a battery in the boot would need cooling. I think it's cooled in the engine bay primarily due to engine bay temps, not internal heating.
These users thanked the author PeteH for the post:
Similarly I've not seen anything in the way of dedicated active battery cooling on batteries stored in boots from factory.
Pipes coming off of them from the battery vents to outside the car however, yes.
Putting one in a rotary engine bay right above the rad however, then yes, duct that sucka.

Unlike motorcycle batteries, few car batteries have vent pipes fitted to take the gases away.
Some just have holes in the cell caps while others pretend to be "sealed-for-life", while having hidden vents.

How about remove the existing vent panels in boot as battery id prefer to be hidden. Remove the insulation on the corner of which the battery will be installed & vent is. Putting a heat repelling material under the mount to prevent/migitate excess heat from the exhaust system. Haven’t done this before. Don’t mind overkill for piece of mind. I can’t place it close to rear seats because of the mazdaspeed strut brace. My BMW battery location (in the boot) hasn’t got any ventilation and is enclosed from what I’ve seen. And with adequate protection device close to the battery that should pickup on current overload.
