Thread: Mounting a second battery under the tray?

Sealed AGMs can usually be mounted on the side.
The one in your pic looks very exposed to rocks.

Hi Tim,
I have mounted an AGM battery lying on its side in the (empty) SLS tray of my Disco 2a.
The situation is a bit similar to what your photo shows, except that I made sure that the battery terminals are at the top.
I made my own protective shield for the battery out of light galvanized iron sheet.

I am a bit puzzled by your photo, 'ços it appears that nothing is connected to the two battery terminals, although there are cables attached to something beneath the battery. How does that work?
It almost looks like a direct short circuit!

Cheers,
AndrewMilne



there is the obvious risk of damage but in the correct cage it would be fairly well protected, what are your thoughts? an i missing another obvious option?


I was thinking of mounting a tray such as this onto the chassis somewhere behind the gearbox area,



thanks,[/QUOTE]

Hi,
I have mounted one on /in front of the right rear crossmember behind the fuel filler neck and fitted an Al shield--it is just a normal deep cycle battery--may depend on how high your tray is above the crossmember.

Thanks for the response guys,

I shamelessly stole the image from google, after trying to find photos of a series or defender with an undertray battery,

i think that vehicle is a chevvy?

as for the terminals? maybe it has 2 sets?

if i end up doing somthing similar i would be looking to protect it alot more

do you have any photos of yours mounted above the x-member? @alan48

Sealed batteries can potentially be laid over but all the strength and bracing is designed for upright mounting. It would be far safer and stronger mounted upright

So Ive done it...

its mounted behind the back wheel on the passenger side,

Ive bolted 40mm unistrut and two L brackets to the rear crossmember, then bolted a metal battery tray on top of that,



then to protect the battery, I had a spare set of mud flaps which i have cut down and fixed to the tray brace above and to the unistrut under the battery, this should protect it from stones / water splashes / mud etc...





its pretty well hidden when looked at from afar:

Great work. Very neat indeed.
