    Where did you get the battery? If it came from Apple, take it back to the Apple store for diagnosis?

    I changed the battery and logic board nearly a year ago now, and it was from a third party store, I would buy a new battery but don’t know if maybe there something else to the problem

    Most likely a bad or flaky battery.
    Buying replacement batteries can be a guessing game:
    Will you get a good one? Or....?

    Is it normal that full charge capacity is greater then design capacity?

    Yes, I've seen this happen with a third party MacBook Air battery I purchased from Amazon.

    The battery looks fine but it could still be a battery problem.
