Has anyone added a leisure battery behind the vehicle battery under the bonnet of a 2.5 TDi?
Today I discovered how difficult it is. It didn't help that the battery tray I bought a long time ago wasn't built with the most accurate precision.
I attempted the method where the leisure batt goes to the back with the vehicle batt sitting in front (offset left), but even to this, it fouls the back of the headlamp connector - basically it's too big. It's a Yuasa YBX 3110, so it's a bit of a beast. The leisure battery is an Enduroline EXV 110 - even bigger, although it sits fine at the back with wiggle room either side.
Then there's the issue of what I think is the ECU and vehicle battery fuse box. If I had a vehicle batt that wasn't as big, say 260x170, then it wouldn't be a problem, but that's not really an option (or is it?). That would mean I'd drop down to about 70Ah.
I've seen other conversions where both batteries sit side by side instead of front and back and wondered if this was an option. I'd also be interested to see where and how the ECU and fuse box have been relocated and where such a battery tray can be sourced. I think I've seen dimensions somewhere to make your own, but time is a bit of an issue.
