Here is a pic that may help.
That is a great picture however some people may not be able to understand it. If you don't mind I am going to try and do a description to go along with it. This description is for 6 volt batteries if that is what you have. 6 volt batteries will have three caps on them.
1. You are going to hook two sets of 6 volt batteries to make the equivalent of two 12 volt batteries we will call these set 1 and set 2
2. We will call the batteries in set 1 Battery A and Battery B, We will call the batteries in set 2 Battery C and Battery D
3. Connect the Negative (-) post of Battery A to the Positive (+) post of Battery B.
4. Connect the Negative (-) post of Battery C to the Positive (+) post of battery D
5. Connect the Positive (+) post of Battery C to the Positive (+) post of
6. Connect the Negative (-) post of battery D to the Negative (-) post of Battery B
At this point you will have one and only one connection to all of the battery posts of the 4 6volt batteries. You will not have any posts without a connection. To test the cables are good take a DC voltmeter and put the positive lead on the positive post of battery A put the negative lead of the meter on the negative post of battery B if the batteries are charged this should read very close to 12 volts dc.
Take the meter and put the positive lead of the meter on the positive post of Battery C and the negative meter lead on the negative post of Battery D this should again read very close to 12 volts DC
7. Take the Positive lead for the coach batteries ( the cable that connects the batteries to the coach ) and connect this to the Positive post on Battery A. This post should now have two connections on it.
8. Take the Negative lead for the coach batteries ( the cable that connects the batteries to the coach) and connect this to the Negative post of Battery B This should now have two connections on it.
This should now be hooked up as a series parallel circuit to allow you to run four 6 volt batteries as the equivalent to two 12 volt batteries.
If you have connections for a charger you can connect them with the red charger (plus lead) to the Plus side of battery a which will give three connections on this post.
You can hook up the black (negative lead) of the charger to the negative post of Battery B which will give three connections on this post
