    2nd battery question

    I will be running a second battery and need to know the minimum size of the wire that can be run from battery to battey??? I was told by one shop only 1/0 and 0 gauge will do...another told me 4 gauge is fine. and alot cheaper since i have laying around...

    Re: 2nd battery question

    And actually you should be fusing the cable between them at both ends as close to each battery as possible. If there is a short in the wire (and you may not even do anything wrong to cause it, some ******* might rearend you, you never know.) you need to remove the current source from the short. You have a current source at each end of that wire so a single fuse isn't going to cut it.



    Artificial Intelligence is no match for Natural Stupidity.

    Never underestimate the power of stupid people in large numbers.

    Life's tough...it's even tougher when you're stupid.

    the wire from the first battery to the relay isolator is a whole 4 inches then the length between the 2nd battery and the fuse is 6 inches so i feel pretty safe but thanks...but i do need to fust the battery to amps now...
