I have one question also. Do you have the Nicad data to enter into a
typical shunt based monitor to calibrate it? Without loading the 5 or 6
parameters a quality battery monitor needs, it really is not going to be
that accurate. It is so nice to have the data from a BMS and no shunt
required. Very accurate Soc:)
