Circuit express battery pack

I purchased battery packs to go with my circuit express kits and they do not fit! What battery pack will fit the express or is there an adapter that I can use to make the battery packs I have work?

Not sure which ones you purchased, but these should work. I have both Microbits and Circuit Express boards and the battery packs that came with my Microbits work with the Circuit Express boards.

I noticed that Adafruit battery packs are currently all out of stock.

Hope this helps.
