I recommend these batteries from aftermarket. They have a USB C port where they can be charged. I connected the upper battery to the USB C 90° cable and led it outside the speaker and plugged it into the power bank. When the lower battery runs out, I change their places. So the speaker can be used longer in a place where there is no electricity.
