The DALY Smart BMS is a comprehensive Battery Management System designed to monitor and protect lithium-based battery packs (LiFePO₄ and others). It features intelligent protection, real-time data communication, and multiple interface ports to ensure battery health, safety, and remote diagnostics. The system integrates UART, CAN, and RS-485 communication along with Bluetooth support for enhanced connectivity. Passive balancing is included to maintain cell voltage uniformity and extend battery life.

Key Features:

• Supports various lithium battery chemistries including LiFePO₄ (configurable series)
• Multiple communication interfaces: UART, Bluetooth, CAN, and RS-485
• Integrated protection against over-voltage, under-voltage, overcurrent, short-circuit, and over-temperature
• Passive balancing to improve performance and prolong battery pack lifespan
• Real-time data monitoring and parameter configuration via app or external controller
• Digital I/O and switch control for custom integration and alerts
• Ideal for solar energy systems, EVs, powerwalls, and industrial battery management
