And then looking at the specifications for the SP140 battery cells: https://cdn.shopify.com/s/files/1/0697/3395/files/samsung-40t-datasheet.pdf?6001754416888422053
- What is the expected lifespan of a battery when determining the SP140 ‘cost per 100 hours’ of $54?
- At what level of capacity loss do you consider the battery to be ‘spent’ and in need of replacement?
According to the datasheet, up to 40% capacity may be lost after 250 cycles. Assuming the pilot only discharges the battery 75% each flight, this gives around 300 hours of flight time prior to the battery capacity being reduced wherein the flight time is only 30-35 minutes.
The only thing I can think of that might affect this is the discharge rate - the datasheet uses a 35A discharge rate and I presume with the high quantity of cells that this will be much lower, which may improve lifespan?
Open to everyone’s thoughts on this
