Calibration is a relatively easy process and will get things back to how they were. The main chip in the BMS is from Texas Instruments and has the part number BQ30Z55. Push on the battery release button or buttons to release the battery form the computer and remove the battery.
One I saw connected of the battery string to the out of the bms to restart it. Check the BMS. But the each cell voltage is fine. Then i thought the battery BMS is shorted or broken.
