LTC2943 : Facing some issues

Hello,

we would like to use board LTC2943 IC for battery status(percentage, voltage, current) while charging & discharging.
so, we did some experiment with LTC2934 board. 
We are facing some issue:
  1. During the charging cycle, Set charge current 2.5A but we are getting around 3A.
  2. During the charging cycle, we are not getting current on V_CHARG/LD pin so we have measured current flowing from the negative terminal of the battery.
  3. During the Discharging cycle , we are not getting same current on GUI and Multimeter.
  4. During the Discharging/Charging cycle,we are not getting same percentage on same voltage.
 
Please find the attached named as "LTC2943 Eval Board Testing" presentation for the result of battery charging/discharging with LTC2943.
Also attached datasheet of battery.
 
 
Thanks and Regards,
Yamini Patel
