Free shipping over $49
60-day hassle-free returns
The MG Master LV 24-48V is the management and safety controller for MG lithium banks running at 24V or 48V. It collects and monitors every essential battery parameter and intervenes the moment any value exceeds safe limits, and its internal main safety contactor will disconnect all chargers and loads if the system ever needs to be protected. It manages up to 96 MG battery modules, communicates over CAN-Bus, and includes Bluetooth Smart for setup and monitoring — the layer that keeps a low-voltage MG system safe and coordinated.
