To charge a 100Ah 12V lithium battery using a Longwei Electric LW Series power supply:
1. Set Output Voltage: Adjust the voltage regulator knob to 14.6V (typical full charge voltage for a 12V lithium battery). 2. Set Current Limit: Set the current (steady flow knob) to a safe charging current, typically 10A or less (0.1C), depending on the battery’s specifications. 3. Polarity: Connect the positive output to the battery's positive terminal and the negative output to the negative terminal. 4. Monitor Charging: Ensure the power supply operates in constant current (CC) mode first, then switches to constant voltage (CV) as the battery charges. 5. Environment: Keep at least 10 cm space around the unit, temperature below 40 °C, humidity under 80%, and avoid dust, acid gas, sunlight, rain, and vibration.
Select a power supply model capable of outputting at least 14.6V and 10A, such as LW-K3010D.
