达锂锂电池保护板4串12V接线教程（4串锂电池保护板工作原理）

Take a 4 series and 12 parallel 18650 battery pack as an example
以4串12并18650电池组为例
Be careful not to insert the protective board when soldering the cable
注意焊接排线的时候不要插上保护板

一、 Mark the order of sampling lines
一、标记采集线的顺序

4 strings of 5PIN cable
4串5PIN排线
Note: The default sampling cable for 4-string protection board configuration is 5PIN.
注：4串的保护板配置的采样排线默认为5PIN。
1. Mark the black cable as B0.
1、将黑色排线标记为B0。
2. The first red cable next to the black cable is marked as B1
2、紧挨着黑色排线的第1根红色排线标记为B1
... (and so on, marked sequentially)
……（以此类推，顺次标记）
5. Until the last red cable, marked as B4.
5、直到最后一根红色排线，标记为B4。
二、Mark the order of battery welding points
二、标记电池焊接点的顺序

Find the position of the corresponding welding point of the cable, first mark the position of the corresponding point on the battery
找到排线对应焊接点的位置，先将电池上对应点的位置标记出来

total positive：总正极 total negative：总负极
1. The total negative pole of the battery pack is marked as B0
1、电池组的总负极标记为B0
2. The connection between the positive pole of the first string of batteries and the negative pole of the second string of batteries is marked as B1
2、第1串电池正极与第2串电池负极的连接处标记为B1
3. The connection between the positive pole of the second string of batteries and the negative pole of the third string of batteries is marked as B2

3、第2串电池正极与第3串电池负极的连接处标记为B2
4. The connection between the positive pole of the 3th battery string and the negative pole of the 4th battery string is marked as B3.
4、第3串电池正极与第4串电池负极的连接处标记为B3。
5. The positive electrode of the 4th battery string is marked as B4.
5、第4串电池的正极标记为B4。
Note: Because the battery pack has a total of 4 strings, B4 is also the total positive pole of the battery pack. If B4 is not the total positive stage of the battery pack, it proves that the order of marking is wrong, and it must be checked and marked again.
注：因为电池组总共4串，所以B4也是电池组的总正极。如果B4不是电池组总正级，证明次序标记错误，务必重新进行检查并标记。
三、Soldering and wiring
三、焊接排线

1. The B0 of the cable is soldered to the B0 position of the battery.
1、排线的B0焊接在电池的B0位置。
2. The cable B1 is soldered to the B1 position of the battery.
2、排线B1焊接在电池的B1位置。
... (and so on, welding in sequence)
……（以此类推，顺次焊接）
5. The cable B4 is soldered to the B4 position of the battery.
5、排线B4焊接在电池的B4位置。
四、 Detection voltage
四、检测电压

Measure the voltage between adjacent cables with a multimeter to confirm that the correct voltage is collected by the cables.

用万用表测量相邻排线之间的电压，确认排线采集到正确电压。
万用表：Multimeter 测量每个相邻电压：Measure the voltage of each ring
电池组电压：Battery pack voltage 排线电压：Cable voltage

1. Measure whether the voltage of the cable B0 to B1 is equal to the voltage of the battery pack B0 to B1. If it is equal, it proves that the voltage collection is correct. If not, it proves that the collection line is weakly welded, and the cable needs to be re-welded. By analogy, measure whether the voltages of other strings are collected correctly.
1、测量排线B0到B1的电压是否等于电池组B0到B1的电压，如果相等，证明电压采集正确，如果不相等，证明采集线虚焊，需要重新焊接排线。以此类推，测量其它串数的电压是否采集正确。
2. The voltage difference of each string should not exceed 1V. If it exceeds 1V, it means that there is a problem with the wiring, and you need to repeat the previous step for detection.
2、各串的电压压差应当不超过1V，超过1V即表示接线有问题，需要重复上一步进行检测。
五、Detection of protection board quality
五、保护板好坏检测

! Always make sure the correct voltage is detected before plugging in the protection board!
！务必确保检测到正确电压后，再插上保护板！
Adjust the multimeter to the internal resistance level and measure the internal resistance between B- and P-. If the internal resistance is connected, it proves that the protection board is good.
将万用表调至内阻档，测量B-到P-之间的内阻，内阻是导通的即证明保护板是好的。
Note: You can judge the conduction by looking at the internal resistance value. The internal resistance value is 0Ω, which means conduction. Due to the error of the multimeter, generally less than 10Ω means conduction; you can also adjust the multimeter to the buzzer. A beeping sound can be heard.
注：判断导通可看内阻值，内阻值是0Ω代表导通，因万用表的误差，一般低于10Ω的都是代表导通的；也可将万用表调至蜂鸣档，导通时能听到蜂鸣声响。
Notice:

1. The protective board with soft switch needs to pay attention to the conduction of the switch when the switch is closed.

2. If the protection board is not conducting, please stop the next step and contact the sales staff for processing.
注意：

1、带软开关的保护板需要注意开关闭合状态下才会导通。

2、如果保护板不导通，请停止下一步动作，联系销售人员进行处理。
六、Connect the output line
六、连接输出线

充放电负极：Charge and discharge negative electrode
电池组负极：The total negative pole of the battery pack
After ensuring that the protection board is normal, solder the blue B- wire on the protection board to the total negative B- of the battery pack. The P-line on the protection board is soldered to the negative pole of charge and discharge.
确保保护板没有异常后，再将保护板上的蓝色B-线，焊接在电池组的总负级B-处。保护板上的P-线焊接在充放电的负极处。
电池组总正极P+:The total positive pole of the battery pack P+
电池组总正极B-：The total positive pole of the battery pack B-
After welding, check whether the voltage of the overprotection board is consistent with the battery voltage.
焊接后检测一下过保护板的电压与电池电压是否一致。
Detect over-board voltage: (B-, P+) voltage = (P-, P+) voltage
检测过板电压：（B-、P+）电压 =（ P-、P+）电压

充放电的正极都是直接和电池组的总正级连在一起的。

The positive pole of charging and discharging is directly connected with the total positive pole of the battery pack.

Note: The charging port and discharge port of the split protection board are separated, and the extra C-line (usually indicated by yellow) needs to be connected to the negative pole of the charger; the P-line is connected to the negative pole of the discharge.
注：分口保护板充电口和放电口是分开的，需要将多出的C-线（一般是黄色表示），接在充电器的负极处；P-线接在放电的负极处。

Finally, place the battery pack inside the battery box, and a finished battery pack is assembled
最后，将电池组放置在电池盒里面，一个成品电池包组装完成
