The BK Precision BA8100 uses the Electrochemical Impedance Spectroscopy (EIS) technology out of the research lab and into the industrial market for diagnosing single battery cells or battery stacks up to 80 V.
Note: All specifications apply to the unit after a temperature stabilization time of 30 minutes over an ambient temperature range of 23 °C ± 5 °C.
