These are very interesting photos...
Above all, you can see that the colleague from China knows the pinout of the "mysterious" connector for connecting a LiPo battery.
... and we know it now.

Can you provide some information about this things? I'm interesting in pinout and type of connector.
Or maybe you have schematics of battery protection board?

Hello!!!!

I have some questions. First at all:

1. Do not I need pin 4 and 5 (SM-Bat_CLK and SM-Bat_SDA)?

2. Can I use this battery without problems?

https://www.aliexpress.com/item/7-4V-Re ... 50457e3507

3. If i use this battery, can I load it over the USB-C-connector on the Alpha? So is a charge controller on the board?

I have some fear because of that test passage in the docs: "And wrong power connection will definitely break for LattePanda Alpha!!!"

Best Regards
