On BTSDA, the formula to calculate charge/discharge DCIR is R= |(V1-V2)| / |(I1-I2)|  Charge DCIR: Using first second record V1 and I1 at current charge step, minus the last second record V2 and I2 at previous charge step. Take the absolute value for (V1-V2) and (I1-I2), we can get DCIR via absolute current value divide by absolute voltage value. Discharge DCIR:Using

About DCIR(direct current internal resistance), usually we care about the discharge internal resistance instead of charge.Accroding to IEC standard, we should use 2 discharge steps together then to get the DCIR values: 0.2C discharge for 10 seconds and 1C discharge for 1 second.Anyway, I just created a testing profile for you to try out on your own BTS4000, you can
