It displays the voltage of the chair battery when you push the button, even when the cover is closed. Generic brackets to fit these are available. Same size as cigarette lighter sockets.
They also fit nicely in any 3/4" nominal electrical box knockout. Nice conduit sized carbide annular cutters are available at the big box stores electrical tool aisle. I think you have metric equivalents across the pond. You can use plastic boxes, or pull junctions as cheap enclosures. If you disassemble a cigarette lighter plug per Burgerman's instructions, you might pot it inside a section of conduit with hot glue.
I found 14AWG 3 conductor outdoor rubber cord on a roll from the big box store fits nicely in the generic XLR connectors from Radio Shack.

just use some dish soap on the cable first to get the strain relief grommet to slide on easy.
If I were to do it again, I would integrate a light with it using something like this

Or to supply a little battery power to the chair without inhibit to move the seat/footrests in case the onboard battery dies completely.
