The design of a battery for a phone is nowhere near the capability of C rate and discharge amperage needed to power multi hundred watt load electric motors. Totally different thing.

Those are some very portable goalposts.

UAVs have high C rates and high durability.

EVs or even aircraft don't need anywhere near 40C.
