Battery pack that big will be better served by a larger connector for power (500Wh battery can sink more than basically any USB-C source can supply),
But the big reason is it's just a big object, and using a little tiny wire and plug on a big object that can fall over is just asking for damage. There's a reason 120V plugs are the size they are, and it's not ampacity. Big connectors for big objects. Small connectors for small objects.
That being said a dual role sink -source controller on a motorized bicycle battery pack would be super convenient for charging phones on the go etc

- 0_____0 3y agoI think you're correctly observing that there's a hole in the available smart charging specifications around the power levels needed for motorized bikes. USB-PD is perfect for most small devices, electric cars and larger have their own protocols, but 0.5-1 kWh batteries are left in the cold. (xkcd 927:1-3)
