 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.

 BMS activation

Method ①

Press the activation button on the Bluetooth module

Method ②

Charge activation

 APP connection

1、When connecting to the APP, you need to turn on the positioning and Bluetooth of the mobile phone

2、Open the "SMARTBMS" APP, you can see the bluetooth serial number on the home page
(this serial number is the same as on the bluetooth module), click and enter to view the battery data.

3、Enter the battery capacity accurately, click "Setting", enter the password 123456,
refresh and the setting is successful

4、The SOC adopts the ampere-hour integration algorithm. When the battery capacity is set correctly,
after a complete charging and discharging process, the SOC is automatically calibrated

 Warning

1、BMS is a professional accessory. Misuse will cause damage. Please operate according to the instruction
manual or tutorial video.

2、BMS cannot be used in series or parallel

3、BMS does not support the use of reduced string numbers

4、BMS to work for a long time in an overloaded state is strictly forbidden

5、Lithium batteries need a dedicated lithium battery charger,
other chargers cannot be mixed to avoid BMS damage and other safety hazards

6、BMS disassembled by the user，No warranty policy

7、BMS is damaged due to unauthorized modification of parameters,No warranty policy
