Yes I’m waiting until it’s ready for the average user before I recommend it to anyone.

Sounds like you’re just running the back end, and it’s using the public front end linked to your local back end by default.

If you want to use port 12470 it says that is https so you’d need to type that in instead of http in your browser.

If you wanted to run the whole thing locally, it mentions disabling CORS, and then you’d probably need to set up the web front end: https://github.com/Stremio/stremio-web

If you want that style of UI use Zen browser, it’s based on Firefox and doesn’t require an account to use it.

Arc is just another crappy browser based on Chrome. The account requirement was and is a huge red flag.

The healthiest is to enable the option to only charge to 80% (or near there, depending on the phone you have).

Otherwise slower charging is better, if the wireless charging doesn’t make the phone hotter than say 30C or so I wouldn’t worry about using it. 45C is the limit for charging Li-ion safely, but it’s better to be cooler.

FolderSync is a good alternative, more battery friendly too!

I would go with a managed Nextcloud provider, it’s such a pain to manage self hosting Nextcloud specifically.

Be extra vigilant with your backups though, free stuff always has a higher chance of weird stuff happening, once they just removed my VPS after my trial ended and told me to re-create it.

Current 18650/21700 Li-ion cells are a lot safer than they were 10+ years ago, less chance of thermal runaway and fires now.

Cell quality is important. You want to be using known good quality cells like those from Panasonic, Samsung, LG, etc…

How you manage temperature, charge and discharge is also really important, dendrite growth can cause cell failure in time. Charge temperature is extremely important. So you want to make sure you’re using a smart programmable BMS where you can set up all the protections properly. Ideally one with as many temperature probes as you can find, 4 is good, 8 is better and some will have that many.

Otherwise making sure nothing can short out internally is important too, but it sounds like you’re putting some thought into that. Most critical IMO from what I’ve seen on pre-made battery packs is making sure your series banks are well insulated from each other and have no chance of vibration causing the cells to wear through their heatshrink and touch each other.
