Question about Bosch eBike PowerPack 500 BBS275

No, it is only conditionally. It costs about 700 francs +/-50. I think it's good, as long as the money doesn't just flow back to Bosch, but also into future battery projects without Lizium. Imagine if this battery or any battery at all with Lizium were cheaper, then our earth would be exploited by even more fools (including me). See the water problem for Lizium mining in areas that are drying up more and more. Whether it's fair that only the "rich" can afford such toys is another question.
I don't think that this battery will become cheaper in the longer term. (Storage of old fashions & scarcer Lizium worldwide.) I'm always glad to see people who think a bit more differentiated and don't argue like that: I want, I need now...
