SKU: SP20S00201-1


1) Characteristics : this is a smart BMS with Bluetooth and PC communication which will be used to protect and monitor your battery status visible from the computer and your android APP phone .which can support three types of communication such as RS485 , UART and CAN communication .
the charge and discharge port is same . Size :145*120*17mm
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) 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 .
And we can design and produce Battery protection circuit board in according to client’s demand with certain
reasonable order quantity .


this bms has three type of communication rs485 ,UART and CAN communication which can work at 100A constant current

Connection instructions :

Please take a reference to this connection picture

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 .?Cwrong 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

Attention : Please use bold and short? wire to make connection for large current distribution purpose to B- port? .the BMS will has possibility to be damaged when using thin and long cable to connect the B- port , 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 !!!


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