i see on my 2016 egolf the tray can hold a larger capacity 12 v battery , any advantage to doing this
 
I don't think so. As soon as your turn the motor power on, there's a 200A DC-DC converter to charge the +12V battery and power the accessories. There's no starter motor on our cars, so no cranking demand. No glow plugs like my TDI either.
