Features and characteristics:

This BMS is an intelligent protection board specially designed for battery packs of electric bicycles and electric motorcycles it can be applied to 11S~15S lithium batteries with different chemical properties, such as lithium ion, Li-polymer. Lithium iron phosphate, etc. The protection board has strong loading capacity and the maximum continuous discharge current can reach 60A.
•11-15cell series protection

• Dimension :130*63*10mm for less than 30A or 130*63*17mm for (40A or 60A )

•Various protection functions for charging and discharging
• Discharge overcurrent, short circuit protection functional processes of hardware
• Overvoltage, undervoltage, temperature, overload protection functional processes of software
•Precise SOC calculation with SOC function of automatic learning
• Discharge overcurrent, short circuit protection functional processes of hardware
• Equipped with Bluetooth module with isolated UART\RS485 communication ,buyer can choose each type of communication based on your demand

A.Mobile Phone APP Display and how to set parameters via APP software with the Bluetooth  Communication module as below.

B .With the PC communication Module as Below ,we can set parameter on PC software like this :

For the connection please take a reference to our other link . thanks

Connection diagram

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 !!!

Reminds : We will send the detail connection drawings to the client with this product if client needs and this BMS will includes all necessories connectors with wire to make sure client can connect it easily . please follow up it correctly to avoid of any mistake ,above connection is only for simple explaination purpose .
1)Do not apply the PCB which beyonds the specified criterias as above :
2)Sometime , the battery may not discharge when connected this PCB , please connect it to the charge and it can recover to the normal status .
3)The PCB may not work normarly When Mixing cells which were over-discharged or over-charged ,
4) Do not shock this PCB with big static even though the PCB has been designed with anti-stastic protection function.
