13S 14S 16S 20S li ion or lifepo4 smart active balance bms with Max 5A balance current for 48V 60V lithium battery bluetooth bms with active equalization

Description Notes:As English APP is under optimizing process , and it will not available with Mobile APP communication current , all parameters can be set via PC software only .  Briefly Introductions : 1) Characteristics : This is a smart BMS with UART  Communication which  can communicate with PC computer with our PC software through connection of our PC Software 2) Dimension :128*80*18mm 2) Application : Client can select suitable series and current from the specification selection list . ( 13S to 20S li ion or lifepo4  can be selected , we will send it to you in according to your ordered specification ) 3) With the same charge and discharge port and balance functions 4) with highly  precision degree on SOC, SOH ,voltage and current metering 5) With full set 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 : 6) with Three temperature detection channel ( one internal and two external ) And we can design and produce Battery protection circuit board in according to client’s demand with certain reasonable order quantity .for other series application : 7) With Max 5A active balance function ( the bigger voltage difference ,the bigger balance current ) 8)  please use the Normal TTL-USB PC adapter module  to edit all parameters . Specification reference : 48V 60V Li ion or Lifepo4 battery smart bms 100A 60A   With Regular UART_TTL adpter module which can fit our bms to edit parameters on our PC software https://www.lithiumbatterypcb.com/wp-content/uploads/2025/03/PC-APP-1.mp4 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 .–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 !!!   Transaction terms : 1) Shipment time : once received your order ,we will proceed it quickly within 3~4 working days without problems .order can be cancled within these days ,otherwise we will reject to cancle the order ,because our items can not get back when in the process of shipment . we will inform our buyer if  there is a stock problems with the order and arrange a properly agreenment on the shipment schedule by email . 2) Shipment Methods : Client can choose suitable shipment methods based on your demand ,Post air parcel service or Express service , 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 . 3) About Tracking number : Tracking number will be uploaded and will be informed by the registered email on each Friday ,please pay attention to your email later on for the tracking number update . 4) Quality Service : 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 . thanks Please send email to this address for any questions [email protected], we will give you reply within 12hours without problems .
