DALY Active Balancing Smart BMS

The DALY Active Balancing Smart BMS combines battery protection, intelligent monitoring and active cell balancing in one battery management system. Designed for LiFePO4, Li-ion and LTO battery packs, the series covers multiple configurations for applications ranging from compact mobility batteries to larger energy storage systems.

Key Features

Active Cell Balancing

Selected DALY models feature bidirectional transformer active balancing, transferring energy between cells instead of simply dissipating excess energy as heat.

Active balancing helps reduce voltage differences between individual cells and maintain better cell consistency, particularly in larger battery packs or systems operating over repeated charge and discharge cycles.

Wide 4S–24S Battery Support

The DALY Active Balancing BMS family supports a wide range of battery configurations depending on battery chemistry and model.

Supported configurations include:

• LiFePO4: 4S–8S / 7S–17S / 7S–24S
• Li-ion: 4S–7S / 7S–17S / 7S–20S
• LTO: 6S–8S / 11S–17S / 11S–24S

30A–400A Current Options

Multiple BMS models are available for different battery pack requirements.

Smart Bluetooth Monitoring

Built-in Bluetooth allows compatible models to connect to the DALY mobile app, giving users a convenient way to monitor and configure the battery management system.

For applications requiring computer-based monitoring and configuration, the BMS also supports PC software on Windows.

Multiple Communication Interfaces

The DALY Smart BMS supports communication options designed for integration with different battery systems.

Standard communication interfaces include:

• UART
• RS485
• CAN

Parallel Battery Support

Selected models integrate support for 1A parallel modules, helping simplify the design of battery systems where multiple compatible battery packs operate in parallel.

Correct system design and configuration remain essential when connecting battery packs in parallel.

Expandable Accessories

The DALY Active Balancing Smart BMS platform supports a range of optional accessories, including:

• Display screen
• Wi-Fi module
• GPS module
• Parallel module
• Buzzer
• Heating module
• Key switch

Accessory compatibility varies by BMS model and configuration.
