1.5v Button battery.What are the wiring methods for iron lithium-ion battery protection board?

　　Analysis of the connection method of the lithium-ion battery protection board: To first understand the connection method of the iron lithium-ion battery protection board in more detail, then it is necessary to understand some basic working principles of the components and protection boards on the lithium-ion battery protection board. This will help Now that you understand the working principle of the lithium-ion battery circuit board, you can better use the iron lithium-ion battery circuit board to connect the battery pack.

　　① Before connecting the cable, make sure that the cable is not inserted into the protective plate;

　　② Weld the b-line (thick blue line) of the protective plate to the total negative electrode of the lithium iron battery;

　　③The wiring starts from the thin black wire connected to b-, the second wire is connected to the positive terminal of the first string of batteries, and then the positive terminal of each string of batteries is connected in turn, until the last string b+;

　　Low temperature lithium iron phosphate battery 3.2V 20A -20℃ charging, -40℃ 3C discharge capacity ≥70%

　　Charging temperature: -20~45℃ -Discharge temperature: -40~+55℃ -40℃ Support maximum discharge rate: 3C -40℃ 3C discharge capacity retention rate ≥70%

　　④After the cable is connected, do not insert the plug straight into the protective plate. Measure the voltage between every two adjacent metal terminals on the back of the plug. If it is a ternary polymer battery, the voltage should be between 2.8~4.2V, and the iron lithium-ion battery should be between 2.8 and 4.2V. Between 2.5~3.65V, lithium titanate battery should be between 1.6~2.8V;

　　⑤ After confirming that the wiring sequence and voltage of the cables are correct, insert them into the protection board socket.

　　Generally speaking: P+ and P- are connected to the output. b+ is connected to the positive pole of the battery, and b- is connected to the negative pole. If multiple cells are connected in series, the negative electrode of b1 and the positive electrode of b2 are connected together, and so on, the negative electrode of the last battery is connected to bn-. Solder the wires first and connect the lithium iron battery last, don't make the wrong connections. If there is no output after completion, remember to use a charger to activate the charging interface led by P+ and P-.
