Ecoflow Alternator Charger 800W

40A plus is a big strain on a 12v system.

And for 50 60 70 80 100 amp circuits , very careful design needs to be implemented ia correct gauge cable grounding fuses and fuse holders.

Second this. I have a mental threshold of 30A - below that things are "everyday" and well within scope of good tidy DIY work, decent cable and easy crimp junctions. Above that you really need to think about routing, length, voltage drop and need more specialist heavy duty crimps and tools - if those are one of jobs maybe get the cable made up, find someone here who has the tools as any DIY savings get erased by the cost of the proper tools (and not using the proper tools generates a potential hot spot where you really don't want one)

As to daisy chaining not much to add to the good advice already given. Just make sure it fits your expected use as if you want to empty the power pack and recharge daily then weak point is going to be the items that charge your LB and you're going to be cycling everything much more. Make sure you have robust wiring and fuses on the existing DC-DC and everything is given as much space and opportunity to cool off; it's going to be operating at peak current for a lot longer than it did to date and that may reveal limitations that were fine but become an issue.
