Battery location
 

Has anyone used the space at the rear either side of the tank to position the battery? Or would it be a ballache to get it out? Just thinking of dumping a bit more of the weight towards the back.

I might be wrong & I openly admit I know very little about auto electrics ( in fact I prefer to keep it that way as I hate the tangled mess of wiring :eek: :D ).

I,m sure I,ve read somewhere that as much as possible to try & keep the battery as close as is practical to the starter motor , I have no idea why but probably some technical reason etc ....but like I say...I might be wrong:confused: :)

Mazda stuck the battery in the boot in the MX5 to even out the weight distribution.
I'd like to think they know a thing or two about auto electrics :)

It'd be best to have it as close as possible to the starter motor to avoid losing a load of volts accross the wire, but if you've got a decent chunky cable it shouldn't matter too much.

That'd be to do with PD and voltage drop over distance and thickness of cable. a long starter motor postive cable would get hot and not spin the starter as fast.

Sven ;o)

Not worried about voltage drop as that can be got around but wondered if with all the panels in place it would be physically possible to get a battery in and out of that space.

i think it would be possible with a small battery, however i would not think it a wise plan since it would be right next to the fuel tank.... fuel vapor from the vent + spark = whizz whizz bang or in the case of a rear end accident could be trouble. i now both of these are unlikely but i dont think mr IVA man would like it on those grounds after all you have to keep the fuel lines and the cables separate in the trans tunnel, would kind of defeat the object if you put the battery next to the tank.

:o As I said I know nothing about auto electrics :o

And thinking about it ....my daily driver( Bmw 5 series) has its battery under the rear seat which I suppose was something to do with weight distribution, cos its HUGE :D

Its for this very reason i think it needs to go in the back. I need a 700amp battery and dont really want to mount it so high on the car. Also battery and under bonnet heat are not best mates.

Bob

what on earth do you need such a big battery for? the battery is only used to start the engine... once the engine is running the alternator provides the power

But they did not have the feul tank sharing the same space as Tilly pointed out.
