Regarding people questioning durability:

BYD batteries are designed to last for 3000 to 5000 charge cycles
If a car has 400 km range on a charge and can handle 3000 cycles, that’s 1.2 million kilometers.
While we don’t know for sure, there has been nothing to indicate BYD should have compromised on that.

A car that has 400 km range which is normal today, would than have a battery lifespan of 1.2 - 2.0 million km.
Corrected for degradation 1.08 - 1.80 million km!!!
EOL is usually considered to be 75-80% capacity. So you could probably use it for years beyond that.
