Good power bank shells for 18650 cells?

[spleenharvester]

I did a cell salvage run on some Dyson batteries to build out a new fleet of Milwaukee batteries and the yield was a lot higher than expected, so I now have a lot of extra Sony VTC4s that are in reasonably good health. I'd like to build them into power banks, there's a glut of shells for 18650s on AliExpress but I don't know which are any good (read: won't explode). Can anyone recommend some (especially the ones that just fit a single cell)? Weld or weldless are fine, I have a spot welder

I suppose USB-PD and/or quick charge would be desirable too

Cheers

You can use hot glue or super glue but be aware of using super glue that once you glue them together and later on you want to separate them you will need to put new heat shrink tubing on them

If these battery cells are going to see a large current load I would highly recommend that you use battery holder/spacers this way it can displace some of heat but more importantly that if the battery cells get so hot that the heat shrink melts and battery cells short out together you are going to have a big problem and mess to clean up the battery cell holder do not cost much at all and are very easy to use
