Descriptions

1) Application : This is The PCB for 3 series or 4S lithium ion or Lifepo4 battery pack with 20A or 30A constant discharge current and charging current . the charge and disc​​​​​​​​​harge port is same . Size :Max60*80*10 mm 2) Protection functions : This BMS has applied with high quality IC chip specially for lithium battery protection purpose .highly detection precision degree on over charge,over-discharge,voltage balancing ,and with detection on wires disconnection functions, with three layers of over-discharge and over-current detections and delay times in detecting process.( Over-current 1, over current 2,short cicircuit protection ) . short-circuit of charging port ,with two layers protection against over-voltage when charging : 3) With Mobile phone operation software systme to manage the detecting the battery working status and some parameters setting . also this board can be available for the PC operation and Parameters setting on the computer . 4) Accessoires : all of our smart BMS will equip wires and connector , with a Bluetooth Communication module included , buy can buy the PC communication module separately if needs

Default parameters

the Parameters of this BMS can be only set by us as below default parameters value for Lifepo4 or Lithium ion battery application .Buyer can not set it with Our PC software .

Product list

Our BMS will include free cable with connector , free Bluetooth module , Client can buy the PC communication module separately without problems if needs

With APP monitoring for two types system

with APP Monitoring software , you can review all kinds of battery information as below picture from Adroid system or IOS APP software

What PC software can do ?

With PC communicaton module , you can set some basic protection parameters the same with APP software , and besides the setting scope , PC Module will extended the parameters setting ,such as battery series setting Cell's voltage calibration . some battery information input in according to the below pictures, client can choose the PC Communication module flexibly in according to your practical application purpose

Connection instructions :

A. Firstly ,Please connect bold wires from B- port of the BMS to the negative port of the battery pack .(B- wire should be as short as possible ) ,then connect these voltage detection wires (Please take off these wires from the BMS before connecting these wires to the battery to avoid any connection mistakes ) B. Second ,Please start connect these balance wires to the Battery system from BC0 ,Black thin wire should be connected to the battery negative , and the second wire -white wire BC1 should be connect to the positive port of the first series cell . BC2 should connect to the positive port of second series cell ,and BC3 wire to the third cell’s positive ….connection in this way in order one by one till to the last cell postive port C. Third . After connection of these balance wires finished , please measure connector voltage from each Neighbouring wires ,the voltage between each neighbouring wires for Li ion battery should be less than 4V and for Lifepo4 Battery should be less than 3.5V ,after confirmation of these wires connection order , you can plug cable connector into the BMS .–wrong connection order will damage our BMS surely . please be carefully with this step . D. Finally , connect C- wire as negative of charge and discharge , B+ wire as positive of charge and discharge , those wires should use bold wire to make connection for large current distribution purpose . then please comparing the voltage from the BMS and voltage directly from the Battery to see if they are the same or not . if they are the same value . your connection is correct , otherwise terrible things will happend !!!
