DALY LFP 15S 120A Same Port Waterproof BMS, For Battery Management

The DALY LFP 15S 120A Same Port Waterproof BMS is a robust Battery Management System (BMS) designed for managing Lithium Iron Phosphate (LiFePO4) battery packs, offering high current handling, advanced protection features, and environmental resilience. Here’s a detailed description of its features:

1. DALY BMS

• DALY is a reputable brand known for producing high-quality BMS systems for lithium-ion and LiFePO4 battery packs. Their systems are commonly used in various applications, including electric vehicles, renewable energy systems, and off-grid power setups.

• 2. LFP (Lithium Iron Phosphate)

  • LiFePO4 (LFP) is a type of lithium-ion battery that uses iron phosphate as the cathode material. It offers:
    • Long cycle life: 2,000+ cycles (much longer than other lithium-ion types).
    • Excellent thermal stability and safety (resistant to thermal runaway and fire)
    • 3. 15S
      • The 15S configuration means the BMS is designed for a 15-series lithium-ion battery pack.
      • Each cell in the LiFePO4 battery has a nominal voltage of 3.2V. A 15S battery pack has a nominal voltage of 48V (15 x 3.2V). The full charge voltage is approximately 57V (3.6V per cell).

      • Key Features:

        • Over-voltage Protection: Prevents battery overcharging, ensuring the battery doesn’t exceed safe voltage limits.
        • Under-voltage Protection: Prevents the battery from discharging too far, protecting cells from deep discharge, which can shorten their lifespan.
        • Over-current Protection: Safeguards the system from excessive current, which can damage the battery or components.
        • Short-circuit Protection: Prevents the system from potential damage in the event of a short circuit.
        • Over-temperature Protection: Monitors and protects the system against excessive heat, which could lead to failure.
        • Cell Balancing: Ensures all cells in the pack remain balanced, promoting longer battery life and better performance.

        Applications:

        • Electric Vehicles (EVs): The high current capacity makes this BMS ideal for large electric vehicles such as electric cars, buses, or electric boats.
        • Energy Storage Systems: For home solar power systems or large-scale off-grid solar/wind energy storage solutions that require efficient and safe battery management.
        • Off-Grid Power Systems: For remote power applications where large, safe, and efficient energy storage is necessary.
        • Marine and RV Applications: Waterproof protection makes it suitable for powering electric boats, yachts, or RVs that may be exposed to varying environmental conditions.

        Summary:

        The DALY LFP 15S 120A Same Port Waterproof BMS is a high-performance, safe, and reliable BMS designed for large LiFePO4 battery packs. Its high current capacity (120A), waterproof design, and balanced protection features make it suitable for a wide range of demanding applications such as electric vehicles, solar storage systems, and marine power systems.
