Backfire G2S owners! I need your help.

EDIT: Solved! Gotten a bunch of feedback from you guys. Thank you!

Hello!

Thanks to the amazing help of this community I have finally decided to the get a Backfire G2S. I had a couple questions about it which I was hoping you guys can help me out with.

1. What is the difference between the 5.0 Ah battery and the 30Q 6.0 Ah battery?
2. Have you had any issues so far with the board? If yes, were you able to get it fixed quickly?
3. After much research it seems that the G2s had a wobble issue that got fixed, does it still happen to you or are you completely satisfied with your riding experience?
4. Does the board have regenerative braking?
5. How is Backfire support? I have heard great things about them so far!

Finally, if you have any experiences to share about the board I welcome those as well! I am looking forward to hearing from you guys and your opinions on the board. Thank you very much for you kind help so far!
