• Within one Mins of static time delay ,the BMS will enter into sleep mode, so as to work at ultral low power consumption in standby time 
• Can connected to our APP where you can monitor all useful battery datas 
• Built with high quality chip with better reliability in low or high temperature environment ,the voltage detection precision can be controlled within 15mV at room temperature , current detection precision will be less than 2%@FS
• Specially designed for large current application purpose , with two layers of over-current protection ,adopted ultral powerful TVS for two directions to prevent large reverse voltage  and current  from shocking the circuit ,applied with Mosfet in TOLL Package which provide much lower resistance and therefore enable larger current distribution safely and reliably 
• With smart Balance management solutions -one click auto balance ,Charge balance , static balance (balance will be done via resistor discharge ) ,when voltage difference goes beyond 10mV, the auto balance will be started , charge balance will work when the voltage gets to our setting value in charging process 

Notes :Please set your battery cycle capacity and typical capacity when you made a new battery system . and please cycle your battery once ( charge your battery fully and then discharge it compeletly so that capacity learning by BMS can be finshed so as to make sure your battery capacity will be accurate )

What Bluetooth Communication Module can do ?

With Bluetooth Communication Module , the android APP Software can be connected , and all information of the BMS can display on your Mobile Phone .  and you can set parametes as below picture .

Remarks :
A. Firstly ,Please connect two 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 !!!
