Another way would be to take the double insulated approach, but to use
SY flex to take the mains in and earth the braid.

As long as you're not planning to take the SY flex into the battery
charger, which would defeat the double-insulated properties of the
charger and be more dangerous!

No, I was thinking of the SY flex being the flying lead used to plug the
charger into the house supply - that being the bit that is vulnerable to
chafing. The charger and its immediate wiring can be secured and protected.

I'm not sure I entirely agree that feeding an earth shielded flex into a
Class II appliance makes it dangerous though. What failure scenarios could
that cause that would result in a dangerous condition?
