Important Notes

• Not for LiFePO₄ (use only with 4.2V Li-ion chemistry)

• Ensure proper wiring of balance leads and power terminals

• Choose the correct communication protocol (UART/RS485/CAN) based on system

• Cooling recommended for extended high-current operation

• Check compatibility with DALY BMS software/app if using smart features
