I currently own a 2021 Galleria with Li3 compared with a newer brand

Yes, do own and enjoy our Greta 2021 Galleria with Li3, which currently has 630Ah.

• A. My Li3 Lithium Battery – 630 amp-hour lithium battery. Voltage regulator, Xantrex XC Pro 3,000W inverter/ charger.
• B. The E1, shows a 6.900 Watt alternator. E1 Package is a powerful Volta Power System. Featuring a high-capacity 12,000-watt-hour lithium battery pack, a 3,200-watt pure sine inverter, two 30-amp converters, and a secondary 51-volt alternator,

Which is a better system and how can I tell, currently I can park for 10 hours with A/C which is a 12V running the clock with no issues. My issues are few and both are Mercedes-Benz. The newer Van has a 144WB and my Greta has a 170WB. I have reviewed tapes and information on the E1 which is most limited.

Sadly this is all I have on both systems and "NO" idea what I should be looking for, as a stand-alone running times. A or B, your thoughts?

From what I'm reading and seeing in this forum I'm back to post some more details, I was concerned about posting in the first post.
A. Vehicle is MB Coachmen Galleria with Li3, but with a 170WB

B. Vehicle is MB Airstream Interstate 19 with E1 and a 144WB

This is a video clip of the "E1 system" shown on a 170WB model. But also comes on the 144WB campervan model which I'm interested in. I hope showing this video will help you help me. A different Lithium Battery power package system. Click Here I've looked around and looked. I would like your help in wrapping my head around this new system.

* Both show 8 to 10 hours of standby operation times with A/C running. Both on the outside seem similar in setup and operation. But over my head to go deeper in reporting facts as I understand them.
* The B, also adds a bit of comfort in knowing there is no propane onboard.

We Love our two inductions Cooktops and the much larger refrigerator. For medications and road snacks.

But I truly would like your feedback as to the two electrical systems. Li3 vs E1,
