Default power bank cases.

if anybody is thinking about getting a shell to put some salvaged cells in,

these ones:
https://www.ebay.co.uk/itm/122705245676

can only supply 800mA
that's not a problem for most uses, but you dont want to charge a phone with it.

based on HotChip HT4928s

i dont like sticking them in parallel.
it only takes one to internally short slowly and it will kill the set.

that's how most of my laptop packs died.

And then sticking them in series requires a charge controller...
