Bosch batteries are made in Europe (Poland) but they can contain Chinese cells.

Bike batteries do not use LFP because bike consumers demand high mileage, small size and low weight.

The Bosch batteries are made very sturdy because bikes experience higher vibrations and water ingress compared to parts in cars.

Bosch batteries are built to be removable on a daily basis for external charging.

I still would say it is too expensive, but it is also not directly comparable.
