Thank you for purchasing use hard switching power supply series
products. In order to make you better use this product, please read the
Instructions carefully before use, and properly kept.
一、Summarize
LW series power supply for high efficiency switching power supply, it
has the load capability is strong, continuous working failure rate is low,
and had a warm, overload, current limiting and various protective
functions. Can be regulated power supply using also can be used for
current, voltage regulator, steady flow can be automatic conversion. Is a
research, colleges and universities, the factory products such as the
preferred power. Specific model parameters are shown in table 1.

Questions and answers
what settings do I use to charge a 100ah 12 volt lithium battery
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.
