Lithium Batteries or AGM / 200 or 400 watt solar?

We currently have a 2019 Unity FX and are going to order a new CB.  We do a lot of boondocking and currently have 200 watt solar and AGM batts.  Want to know if anyone has experience with the new lithiums and if they feel they are superior to AGM and worth the investment.  Also - does the extra 200 watt increase battery trickle significantly.  Many thanks for your thoughts.

If you are happy with what you have now, stay with it. For trickle charging batteries all you need is one 100w panel.  If you want to charge low batteries faster, 400watts is always better.  And Lithium is always better for Boondocking.
For extended Boondocking you never have enough batteries or solar!
Some people have installed over 600 watts of solar and over 600amps of Lithium batteries.  Now there are Lithionics batteries out there that have 315 amps but fits in the same space as two 100a batteries, with many extras.  Do some investigating.
What ever you do don’t order factory upgrades, way too expensive for what you get.  After markets will give you better equipment and probably same you money.

Can you please expand on this a little more. I was in the final stages on going with the LI³ 315ah battery and the options. Are you saying just get the battery and not the other options they have built into it? Where and how much did you pay for your battery please?

I don’t have  Lithionics batteries, but some people say they are comparable in price,  per amp,  to Battle Borns,  if you consider the extras you get withi Lithionics.  And you ask for the special price for Leisure Travel owners.
LTV gets almost $6000 for 400 watts of solar and 200 amps of Battle .born batteries, under another name.

I purchased myself 6-100 amp solar panels, and controller for under $1,000. I also bought a 3,000w inverter $1,200. A LI ³ 315 amp hour with LTV discount for $3,900. Other misc items about $800 for a total of about $6,700. Compared to what you get from LTV. I get about a 1/3 more for less than they charge. Rather than wish I had more we just did it. I get our LTV next month and can't wait to start this project. If you go to the Sprinter Forum you will find a ton of help. It does not seem very complicated if you just do a little home work.  That new 315ah LI³ battery is a game changer for me. Soon I will expand that to 600ah hence why I am adding 600 watts of solar and not 400. Sort of the "Boobdocking" package i think they will offer soon I am guessing.

Other misc items about $800
That's a good chunk of change for "misc items". Care to expand? Are you changing B2B? I suspect you might want to upgrade the cable AWG. And of course some more/upgraded fuses.

Misc items cabling, shunts, caulk, tools, connectors and other small items. The total cost was give or take +- $500 of what LTV charges but you get 6 panels bot 4, 315ah not 200ah, 3,000w inverter not 2,000w and you can if you want resell the 2,000w inverter that comes with it for about $800 to bring cost down further. You don't really need to upgrade any cables as you are adding all new. I also purchased 1 extra 100w panel for $113 jist incase one breaks so I don't have to worry about getting the exact same panel.

If you look at the Sprinter Forum you will see step by step instructions along with a complete parts list with links to all items used by others down to the stainless steel screws. Just add all to your cart and see what options you want. It really could not get any easier.

We bought the 2021 Wonder LTV RL with the optional Lithium Batteries & very pleased.  We had AGM batteries in our LTV Unity TB, 2013 & with my wife & I using CPap Machines, we always seem to have a problem overnight with running very low or below the minimum % of battery in the morning. 
Now with the 2 100 Amp Lithium batteries, plus we installed the Victron Shunt, we have ample power during the night.  The nice thing about the Victron Shunt, you can pull up your app on the phone after you have the Cpaps running & it gives you a reading of how many hours/days you can go with the draw at the time.
Very good investment for us, & glad we did the Lithium's.

We switched from AGM's to 200AH of Lithium. Power is no longer an issue period. I don't even need to plug in. We have all kinds of things running and there is ample power. LTV charges a lot for them, but I would probably just bite the bullet. My 2020 Unity has 200w of solar. It seems fine much to my surprise, but again, would I get the 400w. Yeah, Do you need it, yeah/no. Hey congrats on getting a new one. I hope to see you at the LTV gatherings. Those are a blast.
Thank you wonderful Leisure Travel Van brothers and sisters!
