I have always been guided by my fellow members at that site over the last 4 years.
I have been building a CT for the last 5 months.
I haven't got into the 12Volt thing as yet but did manage to visit "Springers" for an opinion on my requirements this Sat just gone.
I have room for a 2nd bat under the bonnet, but I don't need it for anything in the vehicle, my query was about a 2nd bat system whereby the bat was easily removed from the vehicle to the CT or campsite or
was placed on the CT for transit or I wanted 2xbat in vehicle and a 3rd bat in the CT - sort of built-in redundancy..
They have a ready made steel box (viewable on their web site) that costs about half what it has cost me for my 2x daughters over the last 20 odd years.
But they also have a sysytem that will do it for me, all up installed with a 120amphr AGM batt was just nudging $1k.
