The SOC ist not exactly the same as in Shimano Apps for my new ORBEA Rise M-Team (MY2024) with EP 801 RS and battery Orbea EBT360. While the Shimano App says 50% there are only 46% shown on my Karoo. These 4% remain constant when battery is getting lower.
Just upgraded from 5.0 to 6.0 - same thing!
