Battery cable

Ok, I just replaced the thin 4 gage battery cable I had originally used to relocate my battery to the trunk with 1/0 cable however I'm about 3 feet short (forgot the extra few feet to the disconnect switch mounted on the rear bumper) and was wondering what is the best way to fasten the additional length of cable. Can I use butt connectors or will I lose amperage this way?

splice

Doc here,

You'd be hard pressed to find a "Butt" Splice for 1/0 cable....

What you can find is a bolt on clamp for 2 1/0 cables back at home depot that will go around 2 1/0 cables, then bolt tightly around them.

Next you will need about a 1 pound brick of pliable electrical putty.

After you tightly bolt the 2 together, add your putty in a big ball around the connector. (cover all exposed spots) Then with black tape, wrap the wire about 6 inches before the ball, then around the ball, and about 6 inches after. Reverse the tape direction and do it again (without cutting the tape) Do this 4 or five times.

That will do it. You will have a joint that won't heat or lose current If you do it right. If you get confused, go to the fuse box and meter for your house, follow the 2 inch conduit up and look where the power hooks up from the pole. this is what you want when your done.



Doc

An electrical supply house will have them also, but they will be crimp connectors that require a high dollar industrial crimper. You can do away with the crimp and flow some solder in the connection and cover the connection with several layers of heat shrink tubing.

I like Doc's idea. Look for a U-bolt or Kearny at Home Depot. Should set you back less than $10 and you can make it up solid yourself. Low cost, effective, and durable.

I'm thinking of just biting the bullet and buying the proper length cable. But if I connect the two I'll go with this idea definitely.
