Where to find Battery Chassis?

Hello, I can’t seem to find any shops that deliver to central Europe (Belgium) that still have the battery chassis for the Wio Terminal in stock. Every website I find is sold out.

Are there any places where I can still find this? Are more being produced?

Here they say ‘get one now’. After clicking ‘error 404’ appears. Hope seedstudio will fix this issue.

Thanks, but I’m specifically looking for the Battery chassis

The one from seeed is also sold out https://www.seeedstudio.com/Wio-Terminal-Chassis-Battery-650mAh-p-4756.html
