Product Parameters

UART/RS485/CAN Communication Interface

The Daly Smart BMS is adapted to three communication protocols, and can be connected to the PC SOFT such as a computer, touch screen, etc., to realize intelligent management of lithium batteries. We also provide customized development of communication protocols such as mainstream inverters and Chinese tower protocol.


Bluetooth Smart Communication

Real-time monitoring of battery voltage, total voltage, temperature, power, alarm information, charge and discharge switch and other data can be performed in the mobile APP through Bluetooth accessories. At the same time, you can also set the relevant parameters of BMS in the APP according to the actual situation.


The High-Precision Chips and Functions

Only by realizing high-precision detection and high-sensitivity response to voltage and current, the BMS can achieve great protection for lithium batteries. Daly standard BMS adopts IC solution, with high-precision acquisition chip, sensitive circuit detection and independently written operation program, to achieve voltage accuracy within ±0.025V and short-circuit protection of 250~500us to ensure the efficient operation of the battery and easily handle complex solutions.

For main controlling chip, its flash capacity up to 256/512K. It has the advantages of chip integrated timer, CAN, ADC, SPI, I2C, USB, URAT and other peripheral functions, low power consumption, sleep shutdown and standby modes.

In Daly, we have 2 DAC with 12-bit and 1us conversion time (up to 16 input channels)


Cooperate with Quality Suppliers

Daly cooperates with high-quality suppliers to maintain long-term strategic cooperation to ensure the supply of high-quality parts. Through patented technologies, including high-current wiring design and technology, high-current copper plates, corrugated aluminum alloy heat sinks and other high-quality components can be effective, so that BMS can withstand the impact of high current, and improve its performance and using life.


Meet The Customized Needs of Customers

Due to the characteristics of the lithium battery itself and the complexity of specific applications, the BMS required by customers may not be conventional parameters. In this regard, Daly's R&D team, production team and sales team have rich experience in dealing with this.They can provide customers with real-time and efficient professional services. No matter what kind of customized BMS you need, you can rest assured to leave it to Daly.

Usage Tips

1. The BMS is a professional accessory. Many operating errors will result in product damage, so please follow the instructions manual or wiring video tutorial for compliance operation.

2. Strictly forbidden to reversely connect the B- and P- cables of the BMS,forbidden to confuse wiring.

3.Li-ion, LiFePO4 and LTO BMS are not universal and incompatible, mixed use is strictly prohibited.

4.BMS only be used on battery packs with the same strings.

5.It is strictly forbidden to use the BMS for over-current situation and unreasonably configure the BMS. Please consult customer service if you don't know how to choose the BMS correctly.

6. Standard BMS are prohibited from being used in series or in parallel connection. Please consult customer service for details if it is necessary to use in parallel or series connection.

7. Forbidden to disassemble the BMS without permission during use. The BMS does not enjoy the warranty policy after privately dismantling.

8. Our BMS has waterproof function. Because of these pins are metal, forbidden to soak in water to avoid oxidation damage.

9. Lithium battery pack needs to be equipped with dedicated lithium battery

charger, other chargers cannot be mixed to avoid voltage instability etc. lead to the breakdown of the MOS tube.

10.Strictly forbidden to revise the special parameters of Smart BMS without

permission. Pls contact customer service if you need to modify it. After-sales service cannot be provided if the BMS was be damaged or locked due to unauthorized parameters modification.

11. The use scenarios of the DALY BMS include: Electric two-wheeled bicycle,

forklifts, tourist vehicles, E-tricycles, low speed Four-wheeler, RV energy storage, photovoltaic energy storage, home and outdoor energy storage and etc. If the BMS needs to be used in special conditions or purposes, as well as customized parameters or functions, please consult customer service in advance.
