Note: This protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery, electric fish electric pool, electric bicycle battery, scooter battery, 775(4A) or more motor, 1W fisheye LED lamp, for the above combination purchase customers please pay attention! .

The described power range is suitable for the following products: low-power inverters, massager battery packs, LED lamp backup power supplies, electronics, solar street lamp batteries, monitoring backup power supplies, and other products.

Note: For discharge products above 3A current, the battery discharge ratio should be above 3C. Rate calculation formula: 1C rate battery, 2000 capacity is equal to 2AH*1=2A upper limit operating current. 3C rate battery, 2000 capacity equal to 2AH*3=6A upper limit operating current. In the use of the battery will heat is the battery ratio is not applicable, this situation can 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 (B3), 14.8V (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 four groups of batteries in series, ensure that the voltage of each group is the same. If the voltage is different, 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. Note: Don't mix good batteries with bad ones! The closer the capacity/internal resistance of the 4 batteries, the better! (Use effect of 2 good batteries +2 bad batteries = use effect of 4 bad batteries).

The properties of the lithium battery protection board: Model: Long HX-4S-A01 Long size: 72*17*3.0mm Overcharge voltage range: 4.25-4.35v±0 Overdischarge voltage range: 2.3-3.0v±0.05v Upper working current: 6-8A Working temperature: -40-- +50℃ Upper limit instant current: 12A Storage condition: -40-- +80℃ Static current: less than 30uA Effective life: more than 50,000 hours Internal resistance: less than 100mΩ Short circuit protection: can be protected, need to charge recovery charging voltage: 16.8V-17V

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.
