Is it possible to set the maximum charging voltage to extend the battery lifetime? See detailed article: https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

This is done by the charger The motor controller has nothing to do with this. The default cell voltage on the xiaomi is 4.15V, I charge my cells to 4.10V The charger can be opened (YouTube) and the voltage can be adjusted slightly with a trim potentiometer. The bms firmware can also be modified to limit the charge voltage earlier but that's out of scope for this project
