I am curious about ebike battery weights and specifically internal batteries and I'd like to know if there could be weight saved in this area and if some brands are making lighter batteries with similar WH capacity?

This curiosity stemmed from recently purchasing a Canyon Strive On and Canyon saving 300g using their own battery mounts rather than the generic Bosch ones. Canyon also make a custom 720wh & 900wh battery for the Shimano motor in the Spectral (that my friend has) and it has a plastic housing rather than the metal/alloy housing I am used to with Bosch that I thought would be lighter but numbers online suggest it is heavier than the Bosch 750wh.

Shimano batteries are also metal/alloy and have a similar weight, my Specialized Kenevo had a plastic battery housing but I cannot find weight numbers online.

Below are some quoted weights I found online:

Bosch
500wh 3kg
625wh 3.6kg
750wh 4.3kg

Shimano
504wh 2.9/3.15kg
630wh 3.7kg

Canyon
720wh 4.85kg
900wh 5.86kg

If anyone has the weight of an internal battery please post below. I'd like to know if anyone is ahead in terms of battery weight.
