Overview
Daly Smart BMS LiFePO4/Li-ion accessories cover communication and display add-ons for Daly BMS systems, including Bluetooth, UART/RS485/CAN communication tools, touch display screens, interface boards, temperature sensing lines, and other optional modules. These accessories are used for data transmission, monitoring, and parameter setting, depending on the selected option and the BMS communication port.
Key Features
- Accessory categories: Bluetooth module, UART cable, RS485 cable, CAN BUS, parallel interface board, circular power display board, square power display board, smart active equalizer, cable, 4.3-inch touch LCD, 3-inch display, NTC temperature control line.
- Bluetooth smart communication: Control battery status at any time; view battery information through an app, set BMS parameters, and control battery status (single voltage, total voltage, temperature, power, alarm information, charge and discharge switch, etc.).
- Bluetooth communication distance: 10M distance communication, stable signal transmission.
- UART/RS485/CAN communication: Anti-interference, strong signal, stable data transmission; optional communication methods.
- PC management software support: BMS management software (host computer) developed by Daly; view and set various parameters of the battery.
- BMS parallel interface board: Realize multiple BMS parallel communication; supports RS485/CAN/RS232 communication mode; supports protocol customization and flexible adaptation; must be used with CANBUS BMS.
- One-key wake-up: Through the built-in indicator light, check the battery status at any time.
- 4-way battery temperature control detection: More comprehensive and accurate temperature collection; improved temperature control protection.
- 4.3 inch touch screen: Finger operation; 4.3 large screen design for a clearer interface and more convenient operation.
- Waterproof and moisture-proof: Sealed design with waterproof function for outdoor work.
- Touchscreen use notes: Screen is always on at work; the screen will be black when BMS is dormant. Supports UART and RS485 communication modes. Communication interface should not be wrongly connected to avoid burning out the BMS. In UART communication, BMS cannot be compatible with Bluetooth or GPS. In RS485 communication, it must match the CANBUS BMS. Different communication modes are configured with different communication cable.

Details
Build out a Daly Smart BMS setup with plug-in communication, display, and wiring accessories for monitoring and parameter tuning.
Bluetooth connectivity supports checking key battery data in the app and adjusting available BMS parameters from a phone.
For quick inspections, the Bluetooth module is rated for up to 10 m communication distance in open conditions.
Choose UART, RS485, or CAN communication tools to connect a compatible BMS to a host computer for configuration.
The parallel interface board enables multi-BMS communication and is intended for use with CANBUS BMS systems.
Built-in indicators help confirm status at a glance, with support for 4-way temperature sensing for more complete monitoring.
A 4.3-inch touch LCD provides on-device control with a sealed design intended to resist moisture during outdoor use.
The compact 3-inch display makes it easy to read core values like voltage, current, and temperature without opening an app.
Add a simple capacity indicator panel when a quick, visual battery level readout is preferred over full data screens.
The Daly battery indicator provides a bar-style level display and voltage readout, powered by a 12V supply with low current draw (<20mA).
The Daly smart active equalizer connects via RS485 or UART and is labeled for 16S Li-ion/LTO or 4S LiFePO4 balancing at up to 1A.
Daly Smart BMS PC software lets you view real-time readings and adjust battery balancing parameters such as equilibrium state and current.
The Daly Smart BMS NTC temperature probe plugs into the NTC interface to help monitor battery temperature during use.
Daly positions its smart BMS products around making green energy systems safer and smarter.
DALY BMS is presented as a professional technology company with dedicated office and production centers and ISO9001 listed.
