Has anyone done it ??

I want to move the battery from under the bonnet to in the boot to make some room

Is there anything I need to know / do ? I was goona weld a battery tray into the boot, run a big ass power cable forward to the engine bay and have a couple of battery style posts in the engine bay with everything connected up as it was to the battery.

Is this how its done or am I being a nugget and missing something?
