Expectations for 6 volt batteries
We replaced our two 12V group 24's with two 6 volt golf cart batteries - 220 amp hours. We also have 270 watts of solar, a Trimetric monitor and a Progressive Dynamic 9100 converter with a Charge Wiza...

Are both batteries rated at 220AH at 6v so that when combined you get 220AH at 12v to the RV, or are they each 110AH at 6 volts for a combined 110AH at 12v output?
With two 6v batteries a problem with a single cell is going to have a greater impact than with two 12v batteries when powering a 12v system. The 6v industrial deep cycle batteries like the ones from Trojan are not the same as standard duty deep cycle from other manufacturers in their construction and they will not perform as well. You get what you pay for (except as a taxpayer).
Yes, both batteries (Diehard golf cart batteries, not Interstate as previously stated) are rated at 220 AH and are new. They were tested at the shop with a hydrometer before we took them as they were replacing another set that wasn't performing.
When we switched to 6v we thought we would get longer time than the 12v. Right now, if we were using the furnace at all, we would be lucky to get through one night.
