[0.2] Purpose & Operating Principle

The BCS-12-01 enables safe charging of external АКБ LiFePO₄ / NMC batteries from a vehicle's 12V onboard power grid with zero risk of depleting the primary vehicle battery. The system initiates charging exclusively while the alternator is running, delivering a stabilized charging current.
