EMTB 52V battery on the frame or in the back-pack?

I have been riding my Radon Swoop 170, fitted with the Bafang BBSHD 1700W motor with the 15aH 52V battery in my backpack. I have reinforced it with the motorcycle back protector. While I enjoyed the bike being lighter at the moment, I did not feel very safe... For the tension of the cable, I have used “cable management system“ from my Virtual Reality setup in the room (ängesystem-Virtual-Playstation-Microsoft/dp/B0777H24ZG/ref=sr_1_3?keywords=vr kabelmanagement
