Introducing the ultimate solution for your solar-powered systems: a high-performance lithium battery charger designed to optimize energy efficiency and prolong battery life. This innovative charger operates within a power supply voltage range of DC 4.4-6V, delivering a precise charging output of DC 4.2V. With a maximum charging current of 1A, you have the flexibility to adjust the current by simply modifying the R1 resistor, making it adaptable to your specific needs.
Engineered for smart functionality, this charger automatically adjusts the charging current based on the input power supply's output capacity, ensuring optimal performance. Its precharge adjustment feature is perfect for reviving deeply discharged batteries, minimizing heat generation during the initial charging phase. The constant current/constant voltage operation, coupled with thermal regulation, guarantees a rapid charging rate while preventing overheating, making it a safe choice for your devices.
When the input power voltage is removed, the charger seamlessly transitions into a low power sleep mode, conserving energy. With C/10 termination and automatic recharge capabilities, you can rest assured that your batteries are always ready for use. Additionally, built-in battery overvoltage protection safeguards your batteries from potential damage.
Compact and lightweight, this solar module measures just 18x10.16x2.7mm and weighs only 0.9g (with pin) or 0.6g (without pin), making it an ideal choice for portable applications. The dual LED indicators provide real-time status updates, with a 'CR' LED for charging and an 'OK' LED signaling a fully charged or constant voltage state.
Whether you're harnessing solar energy or utilizing a 5V DC power supply, this lithium battery charger is the perfect companion for your lithium-ion or lithium polymer batteries. Elevate your solar energy experience with this essential charging module today!
