Inside a recalled power bank.
Added 2019-11-25 12:39:12 +0000 UTCThis was sent for our entertainment by a chap called Peter. I finally got round to opening it and analysing the circuitry inside to see if I could work out why it was recalled.
The design looks fairly solid, but they have jammed quite a lot into a small space.

"What's the worst that could happen", said Clive. "Boom!!", said the Lithium cell..

2019-11-27 04:26:15 +0000 UTCDo you mean the X-Ray device? I think that's what it's called... ;-)

2019-11-25 17:47:38 +0000 UTCSeems to me that in the name of thorough investigation you should give the bottom corner of the batteries a whack with the Hammer of Science, to check your theory.
2019-11-25 15:27:09 +0000 UTCIt could be just something as simple as bad workmanship. You said a couple of components were soldered on by hand. Perhaps they had had some failures due to that.

2019-11-25 15:09:37 +0000 UTCYour statement is correct. Thank you.

2019-11-25 13:40:55 +0000 UTCCould it be as simple as the unpeeled adhesive? That pad may be a part of keeping the battery from getting shocks.
