  USB SMBus Interface

Sorry, Vantage is Lenovo software, but it has a function to improve battery gauge accuracy. It made more sense when mentioned in the Thinkpad forum, but I figured I'd crosspost my request here too. That being said they of course did the major dick move of only ever adjusting measured capacity down, even if the cells were literally at 4.1V when the battery said it had run out. Therefore, I first used the smbusb utility to edit the dynamic battery data and blank out the battery full charge capacity (which actually sets it to the absolutely ridiculous 65535Wh). After that when running the gauge reset in Vantage the battery was more than happy to report a more realistic 102.78Wh of actual capacity, despite still reporting a design capacity of only 93.6Wh which thankfully didn't raise any issue. Unfortunately while trying to experiment with the BMS firmware further to try and adjust the voltage thresholds to better fit the new cells, I corrupted something. The BMS still reports and sort of works but whenever I try to make further edits to the firmware I am greeted with errors.
