R66 says nothing about the wires or connectors attached to the battery. It says you can't change or modify the battery (among other things).

I don't see an issue with modifying the connector to mate with another connector. This isn't reducing it's protection from a short or its current carrying capacity of the connector itself. It's like saying a car isn't safe in a crash because you took the dice off the mirror. They aren't integral to the function of the device.
