What is this Giant part ?

Hello Brains Trust. Could someone shed some light on this adapter cable plug, square end with odd single pin below the normal 5 pin charger pins. Appears to have twist locking judging by the arrow and icons printed around the circular edge.

Not seen anything like this before, but then again, we are a little in the dark 'downunder' !

Nice find thanks for that. Giant using a 250w Range Extender battery with another incompatible proprietary plug for the kids bike that doesn't fit any other model.

Then you can't use the kids battery as a Range Extender on the grown ups bike.... why doesn't that surprise me ?
