I agree with you: oXigen can be overwhelming.
That is why there is a wonderful manual describing it in details.
If you have not read it I really encourage you to download it and have a good read:

With the new SCP3 controller, the lipo battery is already included in the case.
I understand that you love you wireless Carrera controllers, but once you try a SCP you will see what it means to have a proper controller.
I am pretty sure that afterwards you will regard your carrera controller as a on/off switch.
