3S 12V 25A with Balance Li-ion Lithium Battery 18650 Charger Battery Protection Board 11.1V 12.6VThe described power range is suitable for the following products: Massager battery pack, LED lamp backup power supply, 12V electronics, solar street lamp battery pack, monitoring backup power supply, and other products. Note: For discharge products above 3A current, the battery discharge ratio should be above 3C. Power calculation formula: 1C power battery, 2000 capacity is equal to 2AH*1=2A operating current. 3C rate battery, 2000 capacity is equal to 2AH*3=6A operating current.

In the use of the battery will heat is the battery ratio is not applicable, this situation must not be used for a long time, the battery will soon be damaged.

Note 1: Wire 0V (B-), 3.7V (B1), 7.4V (B2), 11.1V (B+) strictly according to the diagram, do not intentionally short circuit! Note 2: After the cable is connected, it needs to be charged first before there will be output. Note 3: When connecting three groups of batteries in series, ensure that the voltage of each group of batteries is the same. If the voltage is different, please charge each group of batteries separately and use them in series. In the discharge test, the group of batteries whose voltage drops fast is the differential battery. For some customers with poor electronic foundation, please explain: do not mix good batteries with poor batteries! The closer the capacity/internal resistance of the 3 batteries, the better! (The use effect of 2 good batteries +1 poor battery = the use effect of 3 poor batteries).

The properties of the lithium battery protection board: Model: HX-3S-FL25A-A overcharge voltage range: 4.25-4.35v±0.05v Size: 56*45*4.0mm overdischarge voltage range: 2.3-3.0v±0.05v Working current: 0-25A Working temperature: -40-- +50℃ Instantaneous current: 35-40A Storage condition: -40-- +80℃ Static current: less than 30uA Effective life: more than 30000 hours Internal resistance: less than 100mΩ short circuit protection: can be protected, delay self-recovery.

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
