A call for battery Uber?
I am visiting country X and I want five batteries for a quadcopter Y for the duration of my stay.
Pick them up charged (or not as required) on arrival and return on departure with use/depreciation costs to be paid.
Or have new batteries purchased on arrival and percentage refund as they are returned to the vendor on departure. Obviously would be easier if Lipo's could be fitted with a deep discharge indicator.
There could even be a battery charity that passes used batteries on to those less able to purchase.
