Hi,

How to update correct chemid, if my current battery spec is not known. How to confirm that I updated correct chemid.I'm having ev2400 version 0.18. Bqstudio version 1.10.101.chemupdate chemistry 960.

Thanks in advance, 

Kavya. 

  • Hello Kavya,

    Try updating the firmware on the EV2400. The firmware is available on the EV2400 product page.

    Error code 771 does not look like a valid error code. Can you check again?
