Last night I got the automatic calibration working pretty well. There is still some tweaking needed, but in my testing I saw .0058Ah/minute drift. Looking at the 40Ah example again this puts the BMS at .87% off after 1 hour of use. This is pretty darn good and should be more than adequate for the BMS. Still, I want to repeat the test, try a few different things, and do a longer test to verify info.
