Class B Full lithium No Generator?

[10thtp]

We’re getting a new Coachmen Beyond 22c li3 full lithium power no generator next week to 10 days. We would like to take an extended trip as soon as we get it. Would like to hear from any you who have a coach with the lithium power no generator. How well is it working. What are the pros & cons? Is there anything I should be aware of. I have owned several class A’s DP & gas, going to 22’ B to get away from the handling of a big rig & toad. Just physically can’t do it anymore. Wife & I want to make another crisscross of US before hanging up tha keys. All related input appreciated.

How long you can go without plugging in is a question we really can't answer. How many Amp hours of battery do you have? Are you planning on boondocking or at campgrounds? How many amp hours will you use? Inverter(s)? lots of info needed to give you an idea.

In a pinch just run the chassis motor. You’ll be fine. Have a great trip.

Thank you for your reply’s, your input is much appreciated. If anyone using this system for a few months and have learned a trick or two or mistakes not to make, please share them. At my age with many years experience using motor homes l have found, experience often comes with many mistakes made. Please help me avoid as many as possible.

Thank you for your reply. Right now all I have are ideas from stats. I would like to get some facts from experience.

Sorry, a second look at my response to your post looks a little sharp, please overlook it. Not my intention. I appreciate all input. Thank you.

I certainly didn't see it that way! A lot of your answer is how big of battery(ies) you have and what you plan on running and for how long. I have two 100AH batteries and have gone all night with a 1000w inverter running a residential fridge and a 350w inverter running my CPAP. That's also from going down the road all day with nothing running, not even fridge.

630 AH lithium batteries, 3000w inverter/charger. With full charged batteries Hope to run 120v CPAP + 12v compressor refer + 12v air conditioner (as needed). Would like to use State, Natiinal, and Corp parks as much as possible. Statistics says it’s possible for approximately 8hr depending on how much the A/C is under full load. I’m just wondering if anyone has field experience with this system.

 

[Gronk]

I don't have any experience with lithium so I would just be just guessing, but lot of those parks have electric and water.

Is there solar on the roof?

Is there solar on the roof?

Yes 220W

 

[SaltyVetAdventures]

Yes 220W

With 630ah and 220w solar...you should be fine with everything except the A/C. Not sure on how that will work out.

630ah x 12v = 7560 watt hours. Look at all of your appliances and add up the watts. CPAP with a heated hose and humidifier can use a bit of power. 12v refer won't use much at all once it is cooled down to operating temp. 12v A/C can use about 900 watts per hour! So what you want to do is totally possible but the AC will be the big factor.

Hi Terry,
I'm reading this a year later and considering a purchase of similarly equipped Class B. How have you been faring with that system?

 

[Scotttkd2]

Ditto on the AC usage, what I have read on other forums is the salespitch for using AC on batteries is far from the real world reality. You would need many times the amp hours to be able to run the AC for any decent length of time without killing all of your capacity to run everything else. Just my 2 cents as they say.

The original poster did not say how many 630 ah battery(s) he had. Still not good info to make a decision based on that post. I saw systems with multiple 670ah batteries. Would not work with only a couple hundred watt panels. Looks like burning fossil fuel is the best way to keep them charged.
