++The BMS Main 3 / BMS Main 2R device supports work with two independent (galvanically unrelated) cell series. To monitor the status of two series, two current sensors are used. A series of cells must be equivalent: they must have the same number of cells and the same capacity.
  Since the series of cells can operate at different loads, they must be balanced. For this, the BMS Main 3 provides two signals to power switches: “Balancing series 1” and “Balancing series 2”, as well as a combined algorithm that considers both the voltage of each series and the charge that these series gave load. The “Balancing series 1” and “Balancing series 2” signals are used to connect high-power balancing resistors in parallel with cell series 1 and 2.
