    Did you completely disconnect the 12v battery when you changed the main battery cell? If not, do so for about 5 minutes then reconnect. If the fault returns there *IS* a problem, but more diagnostics will be required to sort it.

    Use the paid version of the app so you can look at HV batttery block data live.

    Then you can see what is really going on.

    For example look at this screen shot of live data. At the time it only had a P0A80 code.
    Looking at the live data you can easy see that block 9 is bad. Much lower voltage than the rest.
