Need electrical help...soon!

We leave Saturday for 2 weeks of dry camping with our brand new travel trailer. After researching, I bought two 6 volt golf cart batteries and hooked them up in parallel. Separately, each battery showed 6.2 volts, but as I have them hooked up they still show the same output. All my connections are solid.

Needless to say, I must have botched something up! I've got one day to figure this out, so any help offered is much appreciated...

    Welcome to the forum.

    From what little I can see, you're connecting the 2 12v terminals together which is incorrect. That's how you wire up two 12v batteries.

    Your method (parallel) will only give you 6 volts as you noticed. Here's a link to make it clear:

    6 volt batteries need to be connected in series to provide 12 volts (12.7v). Connected in parallel just gives you 6.35v and 440 AH.

    A single cable is connected from the "NEG" post of first battery to the "POS" post of the second battery to form one "12 volt" battery and 220 AH.

    Get rid of your link to the picture. It is oversized and messing up reading of your post.

    for the love of god reduce the size of the photo,

    that said you need to wire in series to get 12v
