6v vs 12v

I have 2 12v deep cycle batteries instead of 2 6v deep cycle batteries. Can I connect in tandem and use in my travel trailer? Thnks
  • Yes. Your trailer uses 12v not 6. In order to use 6v batteries, one must connect them together in series to make one large 12v battery.

    Connect your two 12v batteries together in parallel to keep them at 12v and you will be good to go. Keep in mind that both batteries should be of equal age/condition or one will discharge the other.
