Holstein13, wow, I didn't realize that you had 16 batteries...... are they wet-cell or AGM's?

I know that we can also run the A/C on battery power but I just hate to put that much stress on a battery. Going down the road with the engine running and alternators 'alternating'.... I've run two airs to keep the house comfortable.

MM.

the 16 house batteries are AGM's. The two 1,200 cranking amp chassis batteries are sealed but I'm not sure if they are gel or not. How many house and chassis batteries did you get?

BTW, do you mean that you don't want to stress the batteries while boondocked or while traveling with the alternators "alternating?"

If it's boondocking, I can see that and worry about the same thing, but if it's while driving, I'd think it puts very little stress on the battery considering that most if not all the power would come from your alternator.

Hi Holstein13,

I don't want to stress the batteries boondocking while trying to use A/C. Going down the road is fine as the batteries are getting a charge.

Our 'all electric' set up is as follows: (from build sheet)

* 4- 3500 watt -24 volt OutBack Sine Wave Inverters
* 3- Lithium Ion 24 volt Mastervolt Batteries interfaced to the Mastervolt Network for complete monitoring of battery history. Battery life expected to be 10 years.
* 1 maintenance-free generator starting battery with auto boost from house batteries
* Exclusive Liberty Coach engineered Battery Watchdog automatic generator starting system
* Automatic shore power loss generator start control

The Lithium Ion batteries can be rebuilt rather than replaced which will be a big savings at that time. I will not keep this coach for 10 yrs. so it may not apply to me.

(on edit)... remembering that you are quite familiar with Lithium Ion batteries.
