I have two 12v batteries and two 6v deep cycle batteries. The 6v batteries are ran together in series and then ran parallel with the other two batteries. My question is: Can I add a third 6v battery in series with the other two for a total of 18v and then if I run that parallel with the other two will it even out to 14v all around? Or will this damage the batteries?

No. Plain and simple. No. You'll FRY the 12 volt battery, AND your charging system can't charge an 18 volt battery, AND you'll fry your amps trying to run them off 18v. They're designed to run from 12-14 volts.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Thanks. I didn't think it would work but just thought I would ask.
