Hi, could someone let me know the size of the positive battery cable please and also where I could get it from.

Many thanks

You could go for this https://www.autosparks.co.uk/electri...cable-red-25mm . They do a 300A version as well..

From memory, my starter was taking ~185A when I last measured it a few years ago (short-term overdriving the cable unlikely to be a problem with 170A cable.

This is what I used on the TR - https://www.ebay.co.uk/itm/223245453227
From the text on the listing they also do a higher rated cable at 240A.

Hi, When I moved the Battery into the boot under the spare wheel I used secondary welding cable. Not had any problems in 5 years.

Welding cable is very good in having a sheath over the primary insulation which provides very good resistance to abrasion - it's also very flexible and available in a range of sizes. Only downside is that it needs frequent supports when used in a fixed installation to manage the drooping caused by its flexibility.

For a long run, go for bigger cross section of conductor to keep the volts drop (=power loss) down.
