Preparation |
Find the total positive and total negative of the battery pack. |
||||||||||
|
Find B-/P- of BMS |
|||||||||||
|
Insert temperature probe (NTC) into the BMS |
|||||||||||
|
Welding |
Note: When soldering, the balance cable cannot be inserted into the BMS |
||||||||||
|
1、Connect the first string (black) of the balance cable to the total negative electrode of the battery, and the second string (red) to the positive electrode of the first string of batteries.The third string (red) is connected to the positive terminal of the second string of batteries,and so on, until the last string (red) is connected to the total positive terminal of the battery.Then check whether there is any cross in the balance cable or false welding. |
|||||||||||
|
2、After the balance cable is connected, do not insert the plug directly into the BMS.It is necessary to measure the voltage of the adjacent point on the back of the plug. (Regular voltage range: Li-ion: 3.0-4.15V/Lifepo4: 2.5-3.6V) After confirming that the voltage is correct, insert the plug. |
|||||||||||
|
3、Connect the B-(blue) of the BMS to the total negative of the battery. |
|||||||||||
|
Voltage measurement |
measure whether the battery voltage（B+→B-)is consistent with the output voltage of the BMS(B+→P-). |
