110Ah deep discharge battery sold through some disability industry
outlets: £149.95. Exact same battery sold for golf buggy: £60

Flightsafe device: £30. This is a three pin XLR plug with pins 1 and 2
shorted, in red plastic. This inhibits the scooter operation. Cost of
manufacture will be about £1.
cost of manufacture is not the only cost that they have to recover

If a product only sells in low numbers (and a "flight safe" device
aimed at a disability product sounds like a very low potential market)
the costs of development can be a significant part of the individual
sale price
Development? A 0.5" length of wire soldered to two pins?

And it would have to have been developed as part of the original scooter.
Presumably this is a replacement for a lost one.

Yes, these things are often in place when the scooter is delivered to the
customer, if it is delivered in one piece. It's a surprisingly common
item. Disabled people do travel the world you know.

but they are still a very small percentage of the whole

Only once in about 300 flights have I ever shared the plane with a person
who required assistance in getting to/from their seat (which I suspect is a
reasonable proxy for "travelling with their own wheelchair")
