1.The Difference Between Split PortAnd The Same Port:Split port means that the positive and negative poles of charging and discharging should be separated;The charging current and discharging current of the same port are the same,and the charging and discharging are in the same interface.
2.Enhanced Version And Balanced Version:Balanced refers to the use of resistors to discharge high voltage cells during charging,waiting for low voltage cells to charge up the voltage to achieve consistent voltage across all voltages and improve the performance of the entire battery
3.Before installing protection,the batteries must be properly matched (the voltage difference between each battery should not exceed 0.05v.The difference in internal resistance is not greater than 5m,and the difference in capacity is 30mAh lower).The better the battery consistency,the longer the distance traveled,and the more stable the protection performance achieved.
4.Batteries should be connected in parallel before being connected in series,and ensure correct welding(18650 batteries should be spot welded with nickel plates,and other batteries should be soldered with solder).Do not screw them down,as it may burn out the IC of the protective plate.
5.Confirm Whether The Battery Model Is A Lithium Battery Or An Iron Lithium Battery:the protection parameters for the two are different.Lithium batteries include:(ternary lithium, lithium cobalt oxide,manganese oxide),all of which have a reference voltageof 3.7V, collectively referredto as lithium batteries.Therefore,when selecting a protective plate,it is necessary to choose alithium battery protective plate.The reference voltage of lithium iron phosphate battery is 3.2V,so the lithium iron phosphate protection board must be used when selecting the protection board.

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.
