Quark UBEC for my Neu 1515 1.5y/s brushless system ; 5A or 6A? which way should I go?

Hi, Brian.
Thank you for you kind reply. And you are right. I meant Voltage.
The motor you saw on the video footage is another brushless motor that I have.
I have two feigao brushless motors, but I think I killed both of them, one 3 weeks ago, and the other today. The motor you see on the footage is Feigao 540C 8XL 2 pole motor. The motor feels like it doesn't have any magnetic field. Can I simply change the rotor or spindle(I am not quite sure what to call it) to fix the motor? Or it's simply dead? I am really sad about what happened to the two motors... I am afraid that my Neu will go like that again...
