I am planning on fitting an auxiliary battery but all my online searches to date have failed to find even a single image of such an installation. Plenty of "Discovery Series 2" but no original Series II; "a" or otherwise.

Someone must have done this job?

I also plan on fitting a second fuel tank. This will go under the passenger seat so installation of the battery in that position is excluded.

Any thoughts, advice, pictures . . . . . music :D?

Stick it in the tub in a ventilated battery box, not many other options around if you have a second fuel tank.

My S III had a battery box for 2nd battery mounted between the bumper and the grill when I got it, I haven't had a need for a second battery on that one so took the box off. The curved infill that usually sits in that position has been replaced with a flat piece of aluminium.

Cheers, Mick.

Mick. Any trouble with air flow onto radiator? Do you have any photos of the box or the installation?

Do I need to ventilate to a point outside the cab and tub, i.e. truly outside?

In short, no.

On a S11A exmil I had once :(, we had a second battery in the tub and did a lot of k's with it there with no issues at all.

Like I said, I never used the vehicle with the battery in that position, so I couldn't say for sure about it restricting air flow. It was off to one side against the chassis, so away from the main part of the grille on a series III, although a series IIa could be a different story. Sorry, I don't have photos of the installation.

Cheers, Mick.
