1) Application : This is The PCB for 13 series lithium ion battery pack with 100A constant discharge current  and charging current  .
the charge and disc​​​​​​​​​harge port is same . Size :Max138*102*17 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  :
     Buyer can choose BMS with different accessories at different cost , one type include a Bluetooth Module and one type 
includes PC and Bluetooth Module together , please know it kindly in advance . 
And we can design and produce Battery protection circuit board in according to client's demand with certain
reasonable order quantity .
Default Value for this BMS :
this default value was set  by us as below pictures ,  Client can leave a message to  us for parameters setting suggestions for better metering precision purpose . such parameters will be prefered for the parameters setting  A. Battery Capacity  B. Charge and discharge protection values in according to your cell specification  .... etc . we will not adjust the parameters if the buyers suggested parameters has the possiblity to harm our BMS and Your Battery , please understand it kindly . 
We will send the BMS with our default parameters value to our buyer if without any message with the order , please know it kindly in advance and thanks for your support kindly .

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





What Bluetooth Communication Module can do ?


With Bluetooth Communication Module , the android APP Software can be connected , and all information of the BMS can display on your Mobile Phone .  and you can set parametes as below picture .







IOS system

Connection Instructions:

15S Smart BMS 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 !!!
