I just upgraded the firmware to version 3.14 and that did not solve the problem.
You can press STOP for 3 seconds to monitor the voltage of each cell to see if there is any difference between the displayed voltage and your measured voltage? If different, please check if the battery balance port, the wire from balance board to the charger, and the balance board are damaged?
