1) Application : This is The PCB for 4 series 12V(14.6v) Lifepo4 or for 4S Lithium Ion 16.8V or 3S Li ion 12.6V battery pack with

60A 80A or 120A constant discharge current and charging current .

2) Communication type : UART or UART and RS485 , buyer can select suitable communication method flexibility

based on your application .

3) the charge and discharge port is same . Size :Max 138*102*10mm ( For 60A version ) and 138*102*17mm ( For 80A or 120A version )

2) Protection functions :
This BMS has supplied with high quality IC chips specially for lithium battery protection purpose .

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 circuit protection ). short-circuit of charging port ,with two layers protection against over-voltage

when charging :

3) With Mobile phone operation software system to manage the detecting the battery working status also this board can be available for the PC operation and Parameters setting on the computer.

4) This BMS will includes such list :

with one Bluetooth module for Android system only ,4.3Version Above . with wire and connector for the Battery and

Software system of mobile phone will be sent to the buyer .

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 positive port

C. Third . After connection of these balance wires finished , please measure connector voltage from each Neighboring wires ,the voltage between each neighboring 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 happen!!!
