EB200: info the manual omits?

After having the Bluetti EB200 for about 2 weeks and trying to learn about this technology, I've got questions not answered by the user manual. Searching online often yields inconclusive or even contradictory results. For example:
Which is it?

Quandary #2:

1. Battery SoC should be somewhere between ~50-80% for storage
2. The unit should be stored with battery SoC @ 100% if blackout preparedness is the goal

Again, which is it?

A new unit should be fully charged before the first use.

This calibrates the display for the charge level. Not for all power stations necessary, but never wrong.

Perfect for storage is 40 - 50% in a cool place. More perfect is, use the battery. Power stations dislike sitting and waiting.

For a long life span discharge never below 20% and charge in perfect case not above 80%. A slow charging process is better, max load should be 2000 watts.

Thanks for the reply. I was beginning to think this was the wrong place to find answers to questions.

I did charge to 100% before I used it, so maybe I accidentally did something right.

With regard to sitting and waiting, I bought the Bluetti for blackout protection and I don't have much day to day use for it. I suppose I could let it run some fans or power tools from time to time. The latter would be more practical if I had a cart to make moving it around (up and down steps) easier. I did buy a little rolling platform for it, but a hand truck would be my preference... just haven't found one that's both good and cheap.

As for slow charging, my sole means of charging is the power brick (500W@8A) that came with the EB200. I may look into panels at some point but that isn't a priority for now.
