Ensure that the ambient discharge temperature ranges from -15°C to +55°C. Can not charge 1. Check whether the battery is securely connected. 2. Check whether the positive and negative battery terminals are correctly connected. 3. Check the charging voltage matches the battery, the charging parameters are set correctly. 4. Check whether the charging current is greater than 100A and ensure that it is less than 100A. 5. Check whether the battery voltage is less than 9V. If it is less than 9V, use the charger with 0V charging function to charge. 6. Ensure the charging environment temperature ranges from 0°C to +45°C. 7. After the battery is protected by over-discharge, disconnect the load and wait for the battery to recover the voltage before charging, or use the charger with 0V charging function to charge. Battery heats up 1. Check whether the battery is securely connected. The connecting wire should be in contact with the battery terminal. Do not clamp screws to discharge. 2. Check whether the battery cable matches the working current. 6AWG or 4AWG cable is recommended. 3. Check whether the load power exceeds the battery discharge power of 1280 watts, ensure the load power is lower than the required battery power. 4. Ensure the working temperature is lower than 55 °C.
