  === Module balancing ===
  The BMS Main X device supports active balancing of battery modules both in the process of charging and in the process of discharging the battery.
++\\When the battery is charging, balancing is performed by disconnecting the most charged battery modules from the common bus. Before disconnecting the modules, the BMS Main X sends a request to the upper-level system (charger) to reduce the charge current to zero, and after the current becomes zero, disconnects the most charged battery modules.

  When the battery is discharging, balancing is performed by disconnecting the most discharged battery modules from the common bus. Battery modules are disconnected only if the battery discharge current has dropped to the threshold value set in the device settings.
