Ordering an extra AB1000 Battery

Has anyone managed to order and additional Battery for the Solar Flow? I can‘t find the Battery in the Zendure Shop.

Maybe at the Amazon Prime Day🤷‍♂️

Im not found solarflow at amazon 🤔

[unknown]Ich bin aber am überlegen mir ein fünfen Akku zu kaufen aber der Preis schreckt mich noch ab es zu tun.

You can find it at "idealo.de - solarflow Batterie " selled by "druckknopf24.com" 789 €.

At the Zendure website they advertise prime day on 7. July
