I'm using more than one Cellink NEO Extended battery with my PowerCell 8. Why is the app not letting me update the EXT battery capacity?Updated an hour ago
The modern versions of the Cellink NEO Extended 7+ support auto detection when connecting to the PowerCell 8. Battery capacity for the PowerCell 8 is 7,500mAh, and NEO Extended 7+ is 6,800mAh. Once you plug the link cable into the IN/OUT Auto port of the PowerCell 8, the system will update the total capacity (7,600 + 6,800 = 14,300 mAh) automatically. You can verify the capacity by using the smartphone app, Cellink NEO Plus, which shows the total capacity of 14.3 Ah.
Please note that the PowerCell 8 is on the bottom in this photo.
If you are connecting more than one unit of Extended 7+, the auto detection function is not working; hence, please refer to the following photo for the proper connection.

Upon the connection, please key in the added battery capacity manually to the app. For example, if you are adding two units of NEO Extended 7+, please add 2 x 6,800mAh = 13,600 mAh.
