Butt connect 2 battery cables

[TMat]

This a pretty simple question, but I cant find anything to do it with.

I am extending my battery cable which is 1/0 gauge, how do I connect them butt-to-butt. I cant seem to find a crimp connector that big. Can you solder them together?



Any help would be appreciated.

solder is always preferred

With such a big cable I probably would just use a solid single wire but if you have to connect them I would probably put two connectors that have a hole in them and put a screw in them to hold them together.

how long is the cable? are you trunk mounting your battery?

Definitely the best way with cables that big. Heavy crimp-on terminal ends like the ends that bolt to starters or starter relays. Usually require a special crimper with an anvil you pound with a BFH
Also look for a special terminal connector (usually a bolt inside a plastic cover)
Most battery shops should be able to help.

Check at a hardware or welding supply store for male and female end's for welding cable's. The cable will go into a sleeve and be locked in place with set screw's and the end's will twist lock into each other. I have used these on drag car's and they work real well.

If you are set on splicing the I would use a split bolt. Sold in any electrical supply house(maybe home depot or lowes). Used all the time for connecting big machinery. Personally I would run a new wire. Jmo.

the proper cable shouldn't be that expensive... How long do u need it to be?
