I think the usage case for this device LFP is not needed. I carry it to use in the field where there is not power. Light weight is probably the most important. i wouldn't buy this unit to just sit at home and cycle.
Would this run a battery charger to charge deep cycle boat battery? I don't have access to power where I store it, and lugging two batteries back and forth from home is not fun.

These units have a very high failure rate or maybe I'm just EXTREMELY unlucky.
I have purchased 4 sets in total (wanting to only own 2 actually). Out of the 4, I've had 2 of the "extra batteries" fail, and 1 head unit fail. I just purchased a 5th set and I'm praying the extra battery works this time so I can maintain 2 fully working sets. I did try to deal with their warranty department and oh man what a hassle it was, they would ask for silly things like pictures of the unit not working. So I would send a picture (it won't turn on), and I would get a response I just need to plug it in and press power. I got frustrated and just returned to Costco. In one case the extra battery was DoA, in all other cases things worked for a couple months and failed afterwards.
It's worth mentioning that I also purchased an EcoFlow Delta and that failed as well after about 2 months. I just purchased a replacement for it and will return the bad one to Costco later this week.
Honestly, if you are not planning to actively use these devices (so you know when they fail) and are thinking to just store them for an emergency, look elsewhere. I just don't believe you can rely on EcoFlow quality control. The price point is right for my usage, and that's why I have purchased replacement units but if this keeps up I may need to abort the brand all together.
This is one of the few I've seen posted with some real capacity. It's presumably two 50ah batteries rated at 14.4V for 1440Wh total. Amazon is showing 100ah lithium ion batteries at about $400, and deep cycle AGMs for $200. For RVs, a handy person would probably be much better off piecing together a kit with the $200 AGM and more industrial quality components.
What do you do when the battery goes bad? Is there a DIY solution?
Anyone know the battery configuration internally? I would like to extract the cells and use it for other purpose.
It doesn't seem like that idea could possibly be financially viable versus just buying a deep cycle AGM battery, but perhaps you need the lighter weight of lithium ion for your project.

There are definitely some other things to consider before going lead acid, which AGM are. Firstly, you aren't supposed to run lead-acid below 50% so double the capacity when comparing it to lithium, and the weight of agms is already a lot. Now double it, that could mean hundreds of pounds difference which would matter on an RV. Lead-acid also needs to be maintained, as in it needs to be charged regularly. Where lithium can sit on the shelf for months when not in use. And now, over the course of many cycles, lithium is actually cheaper than lead. And when I say lithium I am referring to liFeP04, you wouldn't build a battery system with lithium-ion these days. Watch some Will Prowse videos and he will teach you everything. I first watched his videos because I didn't know what the difference between an amp and a volt was. A couple of years later I bought an RV and built a DIY solar system by my self and enjoyed the whole process as it was fascinating.

Their Delta Max uses NCM (Nickel Manganese Cobalt) chemistry.
You have to step up to the Pro series to get LiFePo4 from them.

Kinda contradicting is it? This IS labeled as "Pro" lol.....
Had this for over a year since buying it from Costco last time. Still amazing as ever.

Delta Pro is LFP. No LFP in River.
