Hello All,
This is a BATTERY CONNECTOR, so that you can use 7.4V(2s) battery to power your Alpha, we will release detailed info and tutorial later.
When we printed the user manual, we still haven't determined whether we can add the interface, so there is a missing information.
How is that tutorial coming along? I would be really interested about more info of that battery connector, is 7.4V 2S Li-Po battery really enough to power the Alpha? Is the connector 10pin JST XH 2.0mm type or something else? What is the pin layout in it? Because of the 10 pins, I assume there is balance charging included?

Most helpful info would be the exact type of the connector, pin layout and maybe diagram of battery wiring to the Alpha :)
It looks like a 10p connector. So I think it's definitely a balance charging connector!

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?
