Daly Smart Active Cell Balancing BMS Smart Cell Balancing

Not only with standard protection, including overcharge, over-discharge, over-current, short circuit, overheated,But also transferring cell power with current between 0 and 1 A Less radiation, less energy consumption, More stable balancing.

Daly Smart Active Cell Balanc4

Sensitive detection Full time smart equalization

It will not be restricted by battery charging, discharging, static, dormant state, etc.Once the cell voltage value and voltage difference reach the set condition,The power transfer will be turned on intelligently until the voltage is balanced.

Daly Smart Active Cell Balanc3

Take a 16 strings battery pack as an example

After 6 hours of active equalization
Set the equalizing current to 0.6A, the voltage difference to 0.02V, and the number of string to be 16.


Smart Communication Real time Monitoring

Both Smart BMS and Smart Active Cell Balancing BMS support communication protocol of UART and RS485 Can also connect to Mobile Phone with Bluetooth APP and computer with USB Cable Real time monitor and set up all the battery information including balancing information

Cable Connection Diagram

The wire routing for BMS of different brands varies. Use the matching cable.

Daly Smart Active Cell Balanc19

Connection sequence of BMS to battery:
※ Special note: Wires from different manufacturers is not universal, please make sure to use matching wires; B- and P- lines of different manufacturers have different colors. Please pay attention to the B- and P- marks.
1.Remember!! Do not insert BMS when welding the sampling wire.
2.The wiring starts from the thin black wire connecting the total negative terminal (B-),and the second wire (red line) is connected to the positive terminal of the first string of batteries, followed by the positive terminal of each string of batteries until the last string of total positive terminal (B+).
3.Do not directly insert the plug into BMS after the cable is connected,first measure the voltage between each two adjacent metal terminals on the back of the plug. The Li-ion battery voltage should be between 3.0~4.15V,LiFePo4 battery should be between 2.5~3.6V, LTO battery should be be-tween 1.8~2.8V, ensure the voltage is correct before the next operation.
4.Connect the B-wire of BMS (thick blue line) to the total negative pole of the battery(b-wire length should not exceed 40cm).
5.Insert the cable into BMS.
After wiring is completed:
1.Measure the battery B+ to B-voltage and B+ to P- voltage is equal(that is battery itself voltage and through BMS voltage is equal. The equal voltage proves that the protection plate works normally. If not, please check again according to the above wiring sequence.)
2.The positive terminals of charge and discharge terminals are directly connected to the total positive terminal (B+) of the battery. The connection mode of the common port BMS is that the negative electrode of charge and discharge is connected to the P-of BMS. The connection mode of the separate port BMS is that the negative pole of charging is connected at C-,and the negative pole of discharging is connected at P-.
Hardware active equalizer connection method
※ Special note: The active equalizer should match BMS with the same strings, and cannot be mixed in different strings.
1.Check and confirm all connection wires are welded correctly after BMS as-sembly is completed;
2.The wiring plug corresponds to the BMS plug and active equalizer plug. BMS plug and active equalizer plug can be used without distinction. Before starting BMS,ensure that the equalizing is properly connected and BMS is securely fixed to the cell. Before connecting BMS, ensure that the connection is correct. Otherwise, BMS may work abnormally or even burn down.
Finally, if you have any questions, please contact customer service to help you solve.

Corporate Mission

Innovating intelligent technology, and creating a clean green energy world.

● In 2012, the dream set sail. Due to the dream of green new energy, the founder Qiu Suobing and a group of BYD engineers started their entrepreneurial journey.

● In 2015, Daly BMS was established. Seizing the market opportunity of low-speed power protection board, Daly products were emerging in the industry.

● In 2017, DALY BMS expanded the market. Taking the lead in the layout of domestic and international e-commerce platforms, DALY products were exported to more than 130 overseas countries and regions.  

● In 2018, Daly BMS focused on technological innovation. The "Little Red Board" with a unique injection technology quickly hit the market; smart BMS was promoted in a timely manner; nearly 1,000 types of boards were developed; and personalized customization was realized.

● In 2021, DALY BMS grew by leaps and bounds. The PACK parallel protection board was developed to realize the safe parallel connection of lithium battery packs, effectively replacing lead-acid batteries in all fields. The revenue this year in DALY reached a new level.
