Power cable size

[Mahooody]

I want a 3rd battery in my tub of my d22 just wondering wat size cable other have used it will have to be big enough for winching to

A 25mm sq cross sectional area flexible copper conductor will suffice, or go up to 35 if your worried.

^ over those distances, at least.

Problem is current drawn through the wire heats it up, makes it dangerous. A cable that long has resistance in it and the ultra-high current makes it heat up really fast.

In all honesty, winch from your starter with your engine ticking over, and if something goes wrong, cart your aux battery around the front and kick your engine over with it (using jumper cables).

Big cables like that are going to need to be supported at numerous places along the way. The weight of the cable causes it to move around a lot, so a long length could be subjected to lots of mechanical stress.

For my money I wouldn't try winching from a battery in the tub. I want something nice and close to the starter for kicking the diesel over!

I be winching off all 3 batteries

That's a little bit pointless....

 

[Mahooody]

Why do you say that it's also for a fridge and so I can have my stereo pumpin all day and all night

 

[Cooper]

If you have three batteries. Use your main for your winch which will be constantly able to deliver the current needed for the winch when in use ( you wont be using it with the vehicle off).

Use the other for your fridge.

And incorporate a 3 position switch for your stereo if you want it to be "Crankin all night and dai mon!"

Do it logically not anally.

Sound easier for me to run one cable than put a switch in
