★Ⅱ、 How to connect wires for BMS
Notes：Please ensure to use sampling wires from HEYO!
1. From the thin black sampling wire to start 2nd thin red wire connects with the 1st battery's positive pole after to connect each cell's positive pole in order until the last on B+.
2. Don't insert the load or charger directly after the sampling wires are connected. Measure the voltage between two adjacent metal terminals on the back of the connector. If it is a Li-ion battery, the voltage should be between 3.0 ~ 4.2V, Lifepo4 battery should be between 2.0 ~ 3.6V and LTO battery should be between 1.5 ~ 2.75V.
3.After the wiring sequence and voltage to confirmed to be correct, then insert into BMS；
4.Adjust the multimeter to the buzzer position and measure the internal resistance between
B - and P - when the internal resistance is 0, there will be a beep, which means that the BMS
is good. Otherwise, do not weld the BMS with a battery. Please contact our customer service for support.
5.The last step to connect B- (thick blue wire) with the battery pack's total negative pole.
★Ⅲ、After wire connection:
Measure whether the B + and B-voltage and B + and P-voltage of the battery are equal. That means the BMS work is normal can be used it doesn't please recheck according to the above wiring sequence.
★Ⅳ、If you have any other questions, pls contact our customer service for support.
