    I GOT P3000 WITH BLOCK 14 LOWEST
    I GOT P0A80 WITH 14 LOWEST
    I HAVE TESTED THIS BATTERY WITH HOBBY CHARGERS DRAING THEM TO 6.2VOLT AND CHARGE THEM
    I HAVE LOAD TEST EVERY CELL WITH A 50AMP LOAD TESTER .. ALL OF THEM HOLD ABOVE 7.2 VOLTS FOR 5 SEC
    IS IT THE BATTERY
    THE ECM
    WHEN I SEE LIVE DATA all cell/blocks ar with in .30 volt of each other

    I live south of you in Olympia... One of the two modules in block 14 has a cell that is starting to fail, but hasn't failed completely... Usually its moduel #28...

    Figuring out which of the two modules, replacing it, then reconditioning whole pack is next step.

    Charging up all modules to max charge and then measuring voltage after a few days (self-discharge test) may help you find which module it is.

    Alternatively, if you're just driving around town and can quickly clear the codes in a way that doesn't complicate your day too much, you can wait till the bad cell gets worse and is easier to identify...
