1awg connector

[TimS]

Well, I am going to install a dual batt set up in a month or so. I have a cobalt pop-up with a battery on the trailer tonque like any other trailer. I just want to isolate it from the truck battery. I am trying to find a water tight female/male connector for the hook-up from the truck to the trailer. The wire size will be maybe 1awg or close to it.
Thanks

Why such huge cable?

It was just an example. I still need to figure out the proper size. I am finding some sources and examples of some good connectors so I am ready when I shop for the items.

Unless you have a huge auxiliary battery and a huge alternator, you can use much smaller cable and save yourself some money and weight! I have a 66Ah Die Hard Platinum in my truck bed with a current monitor, and the maximum sustained current I have seen go to the battery (at 30% SOC) is less than 30 A. If you are in a similar situation, you could probably us 6 or 8 AWG wire.

You're welcome. The powerpoles are quite good connectors. Marine grade connectors are also good but you might have trouble finding them in the sizes you want.

Here is a link to some data on how to calculate your wire size:
