Specification
matters need attention
Please note:When assembling the wiring, weld the cable and the cell correctly, connect the B- of the PCM with the total negative
pole of the cell, and then insert the cable into the needle base on the PCM. (Note: different connection modes for different
strings, and different connection modes for the same port)
pole of the cell, and then insert the cable into the needle base on the PCM. (Note: different connection modes for different
strings, and different connection modes for the same port)
Connections guidelines :
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 !!!

FAQ
1. What type of charger should I choose?
Lithium battery must choose specific charger, do not use Charger for Leadacid battery, for leadacid charger may have MOS with high
pressure breakdown protection, which will not protect of BMS over charge. Life Po4 battery charger voltage=battery string
No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.
2.The relationship between Battery capacity and BMS current?
There is no direct relationship between Battery capacity and BMS current, big capacity doesn`t mean a big battery, but rely on
continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery
capacity.
3.Whether my BMS damaged?
If you want to judge if the BMS is damaged, please take the folowing steps, to test if each cell voltage is the same with
voltmeter? if the cell voltage difference is over 1.0V, the fault is displayed that it cannot run far, no power supply at the
start range, short charge time, all these issues are almost caused by battery cells, if BMS damaged is displyed as no charge, no
discharge, no discharge while the battery has voltage.
