Overview:
The 2-in-1 Lithium Battery Charging Module combines a lithium battery charger with a DC-DC step-down converter, designed for single or multi-cell lithium-ion, LiFePO4, or lithium titanate batteries. With adjustable output and multiple protection features, it is highly versatile and reliable for various charging and power management applications.
Features:
• Adjustable Output Voltage: DC 1.2V to 23V (configurable for 4.2V, 4.3V, 4.35V, 8.4V, 12.6V, 16.8V, 21V).
• Maximum Current: 1A (adjustable by modifying the Rcs resistor).
• Battery Protection: Over voltage protection with automatic adjustment for deeply discharged batteries.
• LED Indicators:
• "CR" LED: Indicates charging status.
• "OK" LED: Signals fully charged or constant voltage mode. After light turns on, please continue charging for 10-20 minutes.
• Environmental Tolerance: Operates in temperatures ranging from -40°C to 85°C.
• Versatility: Functions as a voltage source when no battery is connected.
