🔍 Field Insights from Users

\nRack-mounted high-voltage LiFePO₄ systems like the HV‑204 typically employ a two‑tier BMS architecture: individual cell-level balancing within modules and a master BMS coordinating communication and load management across the rack via CAN-bus. Reddit users note that this ensures stable performance without manual balancing. \n \n
