We use the bq78PL114S12 for a few years now.
During last production, we noticed something strange with the LEDs. The first time we check the SOC status, only one led turns on. When we push the button a second time, all leds turns on (which is correct, because the batteries are fully charged). This happens only the first time for most produced batteries.
Is something wrong? Do you have an idea how this problem can be caused?
