  === Cell balancing ===
--Balancing makes the voltage of all cells equal to the minimum cell voltage.
++Balancing makes the voltage of all cells be equal to the minimum cell voltage.
  The following balancing rules are supported:
--* when the battery is charging (current I > 0) and time after until the battery is relaxed;
++* only when the battery is charging (current I > 0) and some time until the battery is relaxed;
  * when the battery is charging (current I > 0) or when the battery is in a state of relaxation;
  * always (regardless of battery state).
--A balancing resistor is connected to the cell if the following conditions are simultaneously met:
++A balancing resistor is connected to the cell if:
--* the voltage on the cell is higher than the balancing start voltage;
--* the difference between the voltage on the cell and the minimum voltage among the battery cells is greater than the balancing start threshold;
++* the voltage on the cell is higher than the starting voltage of the balancing;
++* the difference between the cell voltage and the minimum voltage among the cells of the battery is greater than the balancing deviation.
--A balancing resistor is disconnected from the cell if any of the following conditions are met:
--
--* the voltage on the cell is less than the balancing stop voltage;
--* the difference between the voltage on the cell and the minimum voltage among the battery cells is less than the balancing stop threshold.

--If the “High logic temperature” occurs, then the balancing of the cells connected to the overheated BMS Logic device will not be performed.
++If the BMS Mini overheats, then the balancing of the cells connected to this device will not be performed.

--The BMS Mini device can enable the cell balancing by the external “Balancing request” signal. Balancing process will be started to cells which the voltage is higher than the balancing start voltage and the difference between the cell voltage and the minimum voltage among all the cells is greater than the balancing stop threshold.
