Availability of Wio Terminal Battery

Hi,

Wio’s Terminal Chassis Battery (https://www.seeedstudio.com/Wio-Terminal-Chassis-Battery-650mAh-p-4756.html) is out of stock and there’s some info here and there about newest version of it.
Is there an expected date for this new extension or availability of ‘current’ one?

Thanks in advance,

It’s available again my backorder has shipped.
