Battery Connections

[Filmshooter]

I’m going to run a 2/0 cable from my house batteries to the battery on our toad. It’s a double cable, so, obviously, 1 goes to hot, but do I run the other to the negative on the batteries or just to frame ground on both ends. Both ends will be fuse-protected. Thanks for any input.

I'm curious why you are doing that.

Agree. Why?

10-12 AWG is big enough for a charge line.

To keep the toad battery charged so the electric brake system works.

12 gauge should be way big enough. If you use 2 conductor 2/0 you won't need a tow bar.

And you'll be able to pull tree stumps for cash with them when you travel.
