Hi,
This is my first post (after lurking on here for quite a while), so my question probably sounds a bit noobish.
Today I received two batteries from an ebay seller, AWT 18650s with a black wrapper and 3,400mA capacity. They have got clear shrink wrap above the printed wrapper, which I removed. However, as I peeled of the wrapper from one of the batteries (I've not checked the other one yet), I was shocked to find out that the PCB was loose, and only attached to the battery by the thin metal strip that runs along its side.
At first I thought I had made a mistake, and that the clear wrapper is a part of the battery that needs to stay intact. But that seems unlikely, as it would be the first ever item that I've owned with a clear wrapper that is meant to stay on the product.
Is it common to find batteries with a PCB that isn't glued or otherwise solidly fixed to the battery itself? Or have I made a mistake, and made the battery unsafe? It seems to work fine, but being new to Li-Ion cells I thought I'd rather ask the experts.
The only other 18650s that I own are Olight ones that came with my SR52, which have a printed wrapper that covers both the battery and the circuit board.
