Product Parameters

Various communication interfaces

The Daly smart BMS has three communication interfaces of UART, RS485 and CAN, which can be connected to the PC SOFT, display screen, mobile phone APP and other host computers to realize the intelligent management of lithium batteries. If you need other communication protocols such as mainstream inverters, Chinese tower protocol, etc., we can provide you with customized development.


Convenient & Intelligent Bluetooth Communication

Except the above three communication functions, the Daly smart BMS can also connect to the mobile phone through Bluetooth accessories to realize the relevant parameter setting in the APP, and monitor the battery data in real time, such as battery voltage, total voltage, temperature, power, alarm information, Charge and discharge switch, etc.


Micro-controller (MCU) chip

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)


High-quality Components

DALY BMS cooperates with excellent component manufacturers to ensure the supply of high-quality parts. At the same time, with exclusive patented technology and professional high-current wiring design, Daly uses high-current copper plates, wave-type aluminum radiators and other high-quality components, so that the BMS can withstand the shock of high current, and protect the lithium battery for a long time.

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.
