bq20z75 v160 shows improper SOC

Hello,

I have created a Golden File for a 4S Li-Ion pack using Molicel ICR18650M with Chem ID 208.  When I program the Golden file in to a fresh pack which is known to be about 35% SOC, the bqEval SOC shows 60%.  Any ideas as to why the SOC is so far off even after performing the learning cycles.  I can provide log data if needed.

Thanks for your help,

Kevin
