Important Notes

• Use only with LiFePO₄ (LFP) cells

• All wiring, especially balance leads, must follow the correct sequence

• Ensure charger and load are within the 60A continuous current limit

• Cooling or airflow may be required in high current environments

• Bluetooth and other smart features depend on the specific DALY model
