BqEASY help with bq3060 BMS IC

hello

we are using the BMS IC bq3060 with the battery pack LiFePo4 6.4V ,9.6Ah. we have got this pack from third party vendor.

after receiving this we have done deep discharge upto the cutoff voltage 5V. and done with charge upto the maximum voltage 7.3V(here in both cases the continous current 1.5A).same time we have used bqEASY to log the data. after doing this for 2 cycles the SOC value(both RSOC,ASOC) is not corrected. and bqEASY showing Max Error 8% in 2 cycles. please suggest us a solution to correct this.

Thanks

Santosh
