Briefly Introductions :
1) Characteristics : This is a smart BMS with UART Bluetooth  Communication function with our Android or IOS
APP , also can communicate with PC computer with our PC software through connection of our PC
2) Widely Application scope  : this BMS can work with 6S 7S 8S 9S 10S Lithium ion or Lifepo4 Battery  with slightly modification with the support of APP and PC software .
3) With the same charge and discharge port and balance functions
4) with highly  precision degree on SOC, SOH ,voltage and current metering
5) With full set 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 :
6) with Two  temperature detection channel
7) This BMS has installed a switch  connector for ON/OFF button connection .
And we can design and produce Battery protection circuit board in according to client’s demand with certain
reasonable order quantity .

How to make correct BMS connection ?

Notice of connection  :

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 !!!
