Bosch don’t really talk about this (prob because they don’t want to admit there’s a battery rattle on many bosch bikes).
If you want to try and dampen / reduce Bosch rattling then try one of these. Cheap and worth a punt. I just fit one to my Rail and I hope it reduces or removes lateral battery movement that can lead to noise.
