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 Wizard.

When we first go into the trailer the monitor says the batteries are at 13.4, which is fully charged. Within 4 or 5 hours the batteries are down to 12.5 and this is after using only the water pump, a few LED lights for a couple of hours and the fridge (on propane) - no furnace.

What can we expect using these batteries? When we had our 12V's we could go several days, even using the furnace and that was before we had the solar.

  • I assume you are in full sun. Measure the voltage on the solar controller input, then on the output.

    I assume 12 volt nominal panels but post the controller model if you have it.

    What other information will be helpful? We'd love to get this figured out.
