Hi,

Which firmware version are you using? We had detected a bug where if we set OCP to the highest bin, the OCP limit will be set to default value of first bin. That might be the reason you are seeing OCP getting hit at 1.3A. This issue will be fixed with next firmware version coming out in few days time.

Regards,
Arun
