Battery Tray for Lightweight Racing Battery.

Hello,
I have decided to stick my lightweight racing battery down where the air filter resonance chamber used to sit behind the driver side fog lamp. I think this would be a good place to keep it out the way, the weight is nice and low and it saves a good few kilo's of battery wire running to the boot.
I will be making one for myself and was wondering if anybody else wants one also? I will post designs here of the tray so you can see exactly what it is like before purchase. Please let me know if your interested. I can't imagine the price for the tray is going to be any more than £30.
Regards,
Adam

My only thought on that idea is what if you need a jump? Is it going to have to be bumper off?...
Though I suppose you don't have to jump it directly on the battery

If you need to jump it the best bet would be to clip one end of the jump cables to the starter motor power connector and another on an end of an earth strap or part of the engine directly next to the starter motor.

Yeah that was the thought after my first thought.
Carry on

Don't think puddles will be a problem, the battery's are sealed so it should be ok submerged, tho how often do you go through puddles that your fog n indicator lights are under water?
I should have something to show later this evening!

Very interesting idea. Neat/Tidy, good use of space/weight distribution and would be original!
As well as the jumping/water problems, I wouldn't think it would fare too well in a frontal or side collision either. Likely to get burst/punctured ?

Ok guys, here we go, I have finished my design, let me know your thoughts:
It will be made from 2mm laser cut aluminium, folded, welded and matt textured powdercoated. The tabs are held on with M3 hank bushes and stainless steel countersunk m3 screws. I have designed the central part of the tray to be universal, the tabs are removable so I can make different types to accomodate different mounting holes on an existing vehicle without having to redesign the whole unit. I can also offer a universal type with full width/height tabs where people can drill the holes themselves.
The battery is held in place with a strap (see last picture).

Looks good bud. Just an idea... Is there any provision for a 3rd fixing (to the car) hole? It's been a while since I removed the resonator in the 4th, so can't remember the number of fixing bolts, but even though your light-weight battery is going to be light for a battery it's still a fair amount of weight hanging on just two bolts, especially for cars that regularly drive on rough roads and speed bumps etc.
