Cable to battery +
Hi All
Relocating the battery to the boot in my mk1, x-flow standard car
My question is what cable grade / type do i need for the positive cable
where is the best place to get this from?
Also what the type of battery ie how many amps etc
rather have it heavy duty.

I have 200 amp cable in mine but have heard dudes using welding cable.
Cheers
Matt

Be wary about manufacturers "supposed" current ratings. Eg, supersh!t auto 200A jumper lead that use 4mm2 cable. 4mm cable in reality is rated to about 35~40amps
The best stuff to get if you can get it is called H07. It's used for flexible mains cables in commercial/ industrial switchboards. If it's in the boot, 35mm2 should be the minimum. 50mm2 is ideal. Not cheap stuff though

Bigger the better... less voltage drop...

The cable style you have quoted is more commonly used for submersible pumps, I know because I use it.
I would just use welding cable, only thing is it commonly comes in black or orange. Any welding supplies or. Electrical wholesaler will stock it. 35mm will be heaps. I ran that on a v8. 35mm should cost about $6-8/m. Ashdown ingrams will stock the auto version which comes in red or black.
Upgrade the alternator feed too while you're at it also.
I think you mean the bigger the better, less voltage drop!

spigot The cable style you have quoted is more commonly used for submersible pumps, I know because I use it. The reason you say it's more commonly used for submersible pumps, is because you work with.... submersible pumps. The reason I said it's more commonly used in commercial/industrial switchboards is because commercial industrial switchboards are found in every single building complex around the world. Supermarkets, service stations, shopping centres, factories etc. How much of this cable would there be per metre compared to.... submersible pumps. Next time your at a woolworths supermarket, ask them to open up a light and power distrubution board and you'll see what I mean.

The h07rnf we get I wouldn't use in a board, but that's probably because 90% of what I pllay with is 1000v.

you would be best to run 70mm2 cable, i ran 95mm2 cable and get 0.8v voltage drop front to back,
we run this on most of our earthmoving equiptment we mod at work due to lower voltage drop
the bigger the cable the more it costs
cheers

it would be a help but you will still have a voltage drop with the battery in the boot
as ratta states" a reduction drive starter " along with that i would leave the battery in the front unless you dont have the room in your engine bay as it may be more of an issue along with extra work to make the battery in the boot LEGAL eg seal boot ,vent battery to the outside,brackets battery boxes ect ect ect
