I must say though - I have seen some silly numbers out of mine and others - such that I don't trust the mA in / out anyway.
I go by the voltage and individual cell results.
There are calibration routines out there written by 'hackers' even to new FW that can be flashed to them.
I also have to admit I have never understood the real need for the PC application that monitors / controls B6 and its sisters via USB ...
