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?
