13s 54.6V li ion 48V Smart BT bms with 30A 40A 60A constant current and RS485 UART communication software BMS Manufacturer

Order Instructions and explaination for Better understanding the specification selection , please take reference to attached explaination of order in advance so as to avoid any selection mistakes 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 10S~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. •12-15cell series protection •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 BT module with isolated UART\RS485 communication ,buyer can choose each type of communication based on your demand Default parameters setting reference This BMS can be set for different protection parameters via APP or PC software setting .our default setting will be as below pictures .Buyer can use our PC communication module to set almost of parameters   Product Pictures These Picures as below is only for the reference, BMS with different constant current will have different thickness , please know it kindly in advance APP application With Bt Communication Module , the APP Software can be connected , and all information of the BMS can display on your Mobile Phone . and you can set some parameters on Your APP software :Over-protection voltage , Over-discharge protection voltage Rlease voltage of over-charge and discharge . Android System APP IOS system APP it can support IOS sytem as below PC software management With PC communicaton module , you can set some basic protection parameters the same with APP software , and besides the setting scope , PC Module will extended the parameters setting ,such as battery series setting Cell's voltage calibration . some battery information input in according to the below pictures, client can choose the PC Communication module flexibly in according to your practical application purpose Connection instructions 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 !!!
