I have a 12s4p battery with Samsung 30Q cells, and one of these battery displays. Currently I have two issues:
The battery percentage is only correct when there is no draw from the battery, i.e. when I’m standing still. Whenever I pull the throttle, voltage drops and the reading is incorrect.
The first 10% go away immediately after just going a couple of 100 meters. After that battery readings seems to be about right. But then the last 15-20% last forever. How can I make this strange curve more into a straight line, as it should be?
