house batteries and generator

My RV will not be used for several months. I want to take the house batteries out and put them on a trickle charger in my house. But I also normally drive the RV every 2 weeks or put a trickle charger on the engine battery, and run the generator for an hour once a month to keep the engine battery and generator running.

Can you run the generator without the house batteries ? Are they necessary to start the generator?

    Hmmm ... if it were me, I'd move to a place where people don't steal cars. ;)


    A hidden battery disconnect switch would be a lot easier than pulling both battery banks.

    Here's your answer...save a whole lot of hassle if you are going to drive it and run the generator anyway. Just make sure to disconnect the batteries when you are done and they should easily hold up for 2 weeks.
  • ^This.
    Or slap a solar charger on the whole thing and fire it up next spring. You’re in SC. Not hard on batteries in the winter.

  • Depends on how your rig is wired. Easy to test - remove the battery and try and start the Generator. If you park your rig near a electric outlet you should just plug it in - most modern converters will maintain your battery without harming it - add in an inexpensive Trik L Charger and your converter will keep your chassis battery charged as well.
  • Usually the house battery but some rv's use the chassis.

    Seems kind of easy to find out. Without being plugged into shore power, why not remove the cables from the house battery and try to start the generator ?

    You might have options:
    Do you have shore power 24/hrs where you park it ? Leave it plugged in if you have a multi stage converter . Some systems like mine use the converter to charge the house and chassis batteries. My solar panel also charges both banks as well . Use a multi meter to test your system to see if they both charge.
