Features

Intelligent control: BMS can monitor and feed back battery capacity, voltage, temperature and battery parameters in real time.

Security: During charging of lithium iron phosphate battery pack, BMS can actively balance the voltage and other states between single batteries to avoid overcharging and excessive heating of the battery

Strong performance: BMS is equipped with microcomputer (MCU) chip and MOS tube to improve the performance and guarantee of the product.

Connection

Applications

LifePO4 Smart BMS is mainly used in LI-ion power batteries and energy storage lithium batteries. Widely used in electric scooters, e-bikes, tourist sightseeing hide, electric tricycles, low-speed EV, emergency UPS, solar street lights, RV& Home energy storage, etc.

Note

★I、Pls do not insert balance wires into BMS before connecting batteries,must make sure connecting with batteries correct.
★II、The order of connecting wires for BMS
Notes: Pls ensure to use balancing wires from Daly!
1. From thin black balance wire to start, the 2nd wire(thin red wire) connect with the lst battery’s
positive pole. Then connect each cell’s positive pole in order until the last one B+;
2. Do not insert the connector directly after the wires were connected.Measure the voltage betwe-
en two adjacent metal terminals on the back of the connector. If it is 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 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 the bms with battery. Pls contact with our customer service for support;
5. The last step to connect B-(thick blue wire) with 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,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 our customers service for us support.
