Product Parameters

High-end BMS

Plastic Injection Waterproof Patent Technology

Daly Smart BMS has special Bluetooth accessories and mobile phone APP, which allows customers to monitor battery voltage, total voltage, temperature, power, alarm information, charging and discharging switch and other data in real time on the cell phone, and also set the relevant parameters of BMS according to the actual situation.

Premium Integrated 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).

Selected High-quality Parts

Using professional high-current routing design and technology, high-quality components such as high-current copper plates and wave-type aluminum heat sinks are used, which can withstand the impact of large currents. Behind every inconspicuous detail, there is quality ingenuity, and the texture can be seen everywhere.

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.
