2x6V Battery wiring question

[Shrek01gt]

Hello, I have a quick question I hope someone can help out with. I'm looking at doing 2 6V golf cart batteries in series for my travel trailer. My question is, if the wires coming from the RV converter are 6 or 4 gauge, is there any advantage to stepping up a gauge for the series connection between the two batteries? (From one positive to the other negative) I would assume you would want the same at the very least but just wanted to see if there was a better option. I was a little suprised how small the house wiring was, maybe because it's a short run or something. Thank you for taking the time to reply.

No not necessary but you can if you wish won't hurt anything.

I use lawn mower battery cables from Walmart. (Battery section). Large wires at a small price.

On of the best things I did was replacing the wire (used 1ga) from the battery to the fuse panel. The jumpers between the batteries are 1ga as well.

I used a 4 gauge connection. The rv parts place I went to was out of stock so they built me one for about $4.00 Canadian.

A larger jumper between batteries will not do anything noticeable, if anything at all.

If the current you draw off the batteries doesn't require you to use larger gauge wiring from the batteries to the converter, then you have nothing to be concerned about.

6 gauge is plenty big. Made mine from wire and ring connectors from Home Depot. That way you can make them the actual length you need. Be sure to crimp and then solder them.

Larger gauge wire will not cause any problem. The idea is to have as little voltage loss as possible. Use heavy cable now and you will not have to upgrade later. Too small of cable gauge will cause problems. Genuine Dealz will make up cables to your length with proper crimped ends. They also have a voltage drop table to check what you need.
