Balance cable connection 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-). If the two voltage values are equal, it means that the BMS is working normally. Model BMS With Bluetooth,Balancing,NTC Optional voltage range：12V 24V 36V 48V 60V Optional current range：40A 60A Usage Scenario Used in RV energy storage,photovoltaic energy storage,home and outdoor energy storage, electric vehicles,tricycles,forklifts,tourist vehicles,golf cart etc. Support Customization Bulk orders can customize functions,parameters,logo. Support OEM Standard BMS, smart BMS all can be customized For details, please contact customer service How to choose the right BMS Attention Illustration Mismatched BMS Consequences Lithium battery type BMS type and lithium battery type must be in one-to-one correspondence（Li-ion/Lifepo4) 1、BMS damaged,even bms and battery burn out 2、The battery cannot be fully charged and discharged Number of battery pack strings BMS strings and battery strings must be in one-to-one correspondence BMS and battery burn out Selection method in experience load maximum power÷(string number of battery×overdischarge voltage)×coefficient Depending on the battery usage scenario, the coefficient value is also different Please consult customer service for specific values Specialty Bluetooth function:You can monitor battery data in real time by connecting to the APP Superiority 1、High-quality microelectronic components：precise and fast IC.Low resistance,high withstand voltage MOSFET. 2、Through the Bluetooth APP, the battery data is constantly monitored. 3、A variety of accessories,can easily control the data and modify the parameters. 4、A variety of communication modes,data monitoring,alarm backtracking,data reading, and upgrade can be easily realized 5、Thermal silica,accelerate the heat dissipation.Ensure the smooth operation of the battery. 6、Preset interface,buckle cable,make the connection more convenient.
