    On my Gen 2 car the battery pack lasted about 16 years. If the past owner had cleaned the HV batt fan or moved the sensors to trigger the fan system earlier, maybe it would have lasted a bit longer. I'm hoping that post rebuild/balance and relocation of the 3 heat sensors to the center of the pack I get 3-5 years more at least.

    I don’t see moving the sensors all to the middle does anything. In other words, 3 sensors reading a higher temp vs just one reading that temp, makes no diff; one is enough.

    cleaning the fan periodically is good though.
