Overview Of Daly BMS

Daly BMS Connection Instructions:

1、PIease do not insert balance wires into BMS before connecting batteries, must make sure connecting
with batteries correctly.
II、The sequence of connecting wires for BMS:
Notes: Please ensure to use balancing wires from Daly BMS
1.Start from thin black balance wire, the 2nd wire(thin red wire) connect with the 1st battery's positive
pole. Then connect each cell's positive pole in order until the last one's positive B+.
2. Do not insert the connector directly after the wires were connected. Measure the voltage between two
adjacent metal terminals on the back of the connector. If it is Li-ion battery, the voltage should be bet-
ween 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 are 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 and contact the customer severice.
5.The last step to connect B-(thick blue wire) with battery pack's total negative pole.
III、After finished wiring:
Measure whether the B + and B-voltage and B + and P-voltage of the battery are equal, If yes, it means
the BMS works normally and can be used. If not, please recheck according to the above wiring sequence.
IV、If you have any other questions, pls contact us for support.
