Not really, just make sure to attach the positive cable to battery one, then parallel battery two, then three, then attach the negative cable to battery three.

You'll likely catch a lot of grief about putting batteries on the ground unprotected, but that's outdated info. Modern cases prevent the grounding out issue batteries used to have. But, you can always get a board to put under the batteries if it's a concern.

Thanks, was thinking about build a rack that would mount them, just while on location, above the present batteries.

Regarding two six volts, I looked at some 6 volts that were 230 am/hrs. does that mean two fo them will provide 230 amps at 12 volts?

thanks in advance

Exactly right, when you connect two 6V batteries in series you double the voltage, but not the amp hours.

But when you parallel two 12V batteries you stay at 12V but double the amp hours.

I like my 6V batteries, I've got four in a series/parallel arrangement. 12V at 460ah.

I wonder what would the cost difference would be between four six volt T-145 and six T-105. I know the difference in amps, I would get more amps

Will the stock WFCO converter handle 6 volts (in series) exactly like a 12 volt. Is that resting voltage for the 2 6 volts about 12.7 volts like the 12'?
thanks in advance.

2 6 volt batteries is series is exactly the same number of cells as a 12 volt battery. No difference except more capacity per cell.

So I've determined that I can fit the Century battery box and 2 - 6 volt batteries in it on the tong of my TT in the usual position. Trojan seems to offer 4 different terminals. Which one do you guys recommend?

The easiest way is to get the same terminals that your current batterys have.

Great thread. Learning alot. IMO regarding 6v vs 12v, you can get approx. 35% more amp/hrs in the same footprint with 6v batteries. Since my batteries are on the trailer tongue, space is paramount. If i'm missing something, tell me.

I have the same setup.....are you sure you don't want 2 T145 30% more capacity for just a few more dollars.
