Earlier, the author proposed a method for constructing a system for reliable operation of a lithium-ion rechargeable battery to power a spacecraft. The method provides continuous monitoring of the voltage of each individual battery element both during both the discharge and the charge process. Here is continued the description of its circuit implementation, the important features of which have not been considered previously. It was established that the rating of the shunt resistor from the gate of the first switching transistor of the measuring cascade to ground is of fundamental importance from the point of view of suppressing the appearance of the effect of measuring switches auto-feeding in the measuring and protective circuits of the local power supply and, therefore, from the point of view of elimination of system disturbances in storage mode.
