Flagstaff Microlite battery question

If all we ran on the on board battery for our Microlite 21FBRS was a small house fan, do you think the battery would last for 9 hours? We have propane for refridgerater.

There is no 110v power available when not hooked to shore power. You can use a little fan like this which will run a long time on battery power. Peak PKC0JH 12 Volt 6" Clip-on Fan: Automotive

I have a dual battery setup on my Micro lite 25DS and can run my heater all night long plus lights and water pump.

We are able to have 110 run this way. Of course we would not use the tv as it would really drain the battery. But as you can see, it does work. Just not sure how long with a small fan. I have read not to totally drain the battery as you will shorten the life. I am looking for about 4 hours of usage. possible?

Can't tell you much about actual run time but if you can use a 12 volt fan instead of a 110 volt one run off an inverter it will give you more run time. There is an amount of waste in an inverter that you will not get with a direct 12 volt fan.

There will be more than just the fan running off of the battery i.e., water pump, carbon monoxide & propane detectors, water heater electronic ignition, and lights. Be sure to turn off your TV amp. Don't discharge your battery more than half way. If you do you will reduce the life of it. Always be sure the water is topped off.
