Fast and Efficient Charging: </strong>The 3A polymer lithium battery quick charging board allows for speedy and efficient charging of your devices. Say goodbye to long waiting times and enjoy fast power replenishment.<br /> <strong>2. Intelligent Charging Control:</strong> Equipped with the IP2312 main control chip, quick charging board offers a complete CC/CV charging mode. It automatically adjusts the charging current and voltage according to the battery's needs, ensuring safe and optimal charging performance.<br /> <strong>3. Multi-Protection:</strong> Rest assured that your devices are protected while charging. Polymer ternary lithium battery charger module has built-in safeguards against overcharging, overcurrent, and short circuits, providing comprehensive protection for both the battery and your device.<br /> <strong>4. Convenient Charging Status Indicator:</strong> For power supply module board, with the red working indicator light and blue full indicator light, you can easily monitor the charging process. The red light indicates when the board is operational, while the blue light signals when the battery is fully charged.<br /> <strong>5. Versatile Compatibility: </strong>Charging management board is designed for 3A charging, but it can be adjusted by changing the resistor to achieve different charging currents (2A or 1A). It is compatible with various devices, making it a versatile charging solution for your electronic devices.<br /> <div> <br /> </div> <br /><br/><br/><strong>Specification:</strong><br /> Origin: Mainland China<br /> Type: Module<br /> Condition: New<br /> Product name: Quick Fast Charging Board (note: not suitable for 3.2V lithium iron phosphate batteries)<br /> Model: AILAV1-0503V3<br /> Main control chip: IP2312<br /> Input voltage: 4.55.5V<br /> Charging cut-off voltage: 4.2V/4.35V (there are two optional output voltage versions)<br /> Charging current: 3A (current can be changed by adjusting the resistance)<br /> Indicator light: yes, red: work indicator light, blue: full indicator light<br /> Conversion efficiency: 3A 93%, 2A 94%, 1A 95%<br /> IP2312 adopts a complete CC/CV charging mode:<br /> When the battery voltage is below 3V, enter the trickle charging mode and charge the battery with a charging current of 100mA.<br /> When the battery voltage is greater than 3V, enter the constant current charging mode to charge the battery with the set constant current charging current.<br /> When the battery voltage approaches 4.2V and the charging current is less than 300mA, enter the constant voltage charging mode.<br /> 4. After entering constant voltage mode, stop charging every 4 minutes and check if the battery voltage is higher than 4.15V:<br /> If it is higher than 4.15V, stop charging; Otherwise, continue charging and test after another 4 minutes.<br /> 5. After the battery is fully charged, if it is detected that the battery voltage is below 4.1V, it will start charging the battery again.<br /> Current regulation instructions:<br /> Default 3A, remove resistor 2A and replace with 135k resistor 1A<br /> <br /> <strong>Note:</strong><br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
