1)  Application :This is The PCB for 10S 11S 12S Lifepo4 13S 14S 15S li -ion battery application with 100A constant

discharge currentand charging current  .the charge and discharge port is same . Size :Max138*102*17 mm

Client should choose suitable series BMS for your battery .

2) Each BMS will be equipped with a bluetooth Communication Module , buyer can add PC communication

module if needs . ( Clinet can choose PC Module based on your demand )

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 :

4)  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 .

And we can design and produce Battery protection circuit board in according to client's demand with certain

reasonable order quantity .

2) Default Parameters setting :

these Are default values for our BMS , it can be set via PC communication module and some can be set via Bluetooth Communication

Module . for better prcision display , buyer can leave us your battery basic information to us for better metering result : Such as Full

capacity of your battery Pack , Over-charge and discharge protection specification of your battery ...etc

3) Product List :

Our Smart BMS with Bluetooth function will include free Bluetooth module and connection cables .if client needs PC communication module , you can buy it separately without problems

Buit with High quality MOSFET with Low Inner impedance for large current of charge and discharge , with 100A constant charge and discharge

PC parameters setting with software operation:

What PC communication Module 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

APP software Display :(Only Selected three pages for simple instructions ,there are another more pages with APP software Management

Please know it kindly in advance )

Just take 20S Lithium Battery connection as a example show on APP software , 13S will be a little bit different , please know it kindly in

advance )

What Bluetooth Communication Module can do ?

With Bluetooth Communication Module , the APP Software can be connected , and all information of the BMS can display on your

Mobile Phone .  and you can set some parameters on Your APP software :Over-protection voltage , Over-discharge protection voltage

Rlease voltage of over-charge and discharge .

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 !!!

Shipment :

Client can choose suitable shipment methods based on your demand ,Post air parcel service aliexpress standard service or Express service will all be available, we will ship all orders strictly in according to the selected shipment methods by our customer . normally , Post parcel shipment time takes 7~60days depends on different countries serivce . and express takes 2~15days to the destination normally .

for the shipment ,client should afford the import tax or duty cost and take charge of custom clearance with our support positively ,as a seller , we wont afford any extra duty cost on buyer side if the buyer custom need to charge it .

Quality warranty:

For our Product , we made twice full inspection before the delivery so as to make sure to low the quality risk in a very lower level .we will take a full responsibility for any defect product caused by our design and production problems ,warranty time is 12 months since the shipment date . but for any defect product caused by any wrong or slavery application from customers . we will not take the responsibility for that , because for this BMS product ,it do need some skills to make installation . please consult us in advance if you are not clearly with bms connection in the hope of avoid any mistakes of connection . if Buyer damaged the BMS , we can offer the free repairing service to our client , but client should take care of shipment cost .please know it kindly in advance . thank

Problems Shooting :

when clinent found there is any problems with our product or with shipment , quantity less ,product damage or other problems with our transaction , please inform us in advance to quickly find a solution for both side before lodge the dispute . Business needs mutual support , let solve any problems in friendly understanding ways .
