    After replacement, the first time power on:

    I found the FCC is 0, so I did power cycle:

    so why first time power on, the information is incorrect?

    Hello Harry,

    So you swapped battery packs between boards, on initial power up the FCC and RemCap both report 0, then you power cycle the gauge and the FCC and RemCap are updated?

    There are some configurations you can change using the NR bit (non-removeable pack) that could affect when you remove/insert a battery.

    Can you share your .gg file so we can take a look at the parameters you have set?

    Sincerely,

    Wyatt Keller

    Yes, you are right. And will it trigger SUV PF fault if I remove battery pack?
