From what I can gather, using your normal ICE 4awg is not recommended for using with a relocated car battery. Most state "not suitable for using with starters and other car accessories"

So, what WOULD be the best cable then? If I were to raid a set of jump leads, would one of those cables be big enough? Any tips on where to get the kind of grade cabling I need would be excellent.

hi there if you go to a welding supply company the ground cables they use will cope with battery volt and amps no problem cut by them to length:thumbup:

I thought you were trying to cut down on the weight Jason....that battery cable is HEAVY ...don't forget increase the size the further it goes towards the back of the car if you do though.....starter motor can draw up to 200amps

I know its ultimately defying my weight loss program.

But I think the weight redistribution overall will help a lot.

zero gauge cable should be enough i would have thought as it has quite a large cross sectional area and where its made of very fine strands this increases its current carrying and its heat disapation

looking on t'internet zero gauge is good for 245A for chassis wiring and 150A for general power transmission. for the brief couple of seconds i'd say zero gauge is big enough but if you want to be totally sure go for either 00AWG or 000AWG

most caravan/motorhome suppliers have this sort of cable in stock, if you are looking for a decent battery tray for the rear wheel recess, the one from a lupo gti fits into a fabia very nicely, it even screws down using that plastic wheel retainer jobby too

i would say that the biggest problem you will encounter is finding a crimping tool big enough to crimp the battery termanials, i have one here if you need to borrow it

the crimping tools are easy to find but expensive to buy, they can be hired from a decent/large sized hire company that deals with electrical contractors

again I'm not sure in the benefit of a few lbs here and there but try an odyssey battery instead of running a cable the length of the car, the battery is less than half the size and weighs in at 14.5 lbs compared to 35lbs that a standard battery is,

If you really want that weight distribution, stick an extra tenner in the tank.

sounds like a much easier and cheaper option there J

to give you an idea of the size of it, theres a picture on RobDon's website beside a phone

Not sure i like the idea of using a motorcycle battery to crank over a TDI. :confused: A 20lb weight saving is enticing though.

the physical size of a battery means nothing J, its all down to its AH rating.

a cheap but physically big battery won't have the same capacity as a very expensive battery half its size.

If you read into it it's not 'just' a motorcycling battery, its a race battery, and the figures it puts out are more than capable of cranking over a TD'I and all its ancillaries, Trust me
