DALY LFP 15S 150A Same Port Waterproof BMS, For Battery Management

The DALY LFP 15S 150A Same Port Waterproof BMS is a high-performance Battery Management System (BMS) designed for Lithium Iron Phosphate (LiFePO4) battery packs. It’s tailored to meet the demands of high-power applications, providing essential protection and ensuring safe, efficient operation of the battery. Here’s a detailed breakdown of its features:

1. DALY BMS

• DALY is a leading brand known for producing reliable, high-quality BMS systems that are widely used in electric vehicles (EVs), renewable energy systems, and other power storage applications.
• Known for their ease of integration, robust protection features, and user-friendly design, DALY BMS units are trusted in both commercial and DIY battery pack applications.

2. LFP (Lithium Iron Phosphate)

• LiFePO4 (LFP) is a popular lithium-ion chemistry known for its excellent safety, long cycle life, and thermal stability. LFP batteries offer:
  • Superior safety: LiFePO4 is more stable and less prone to thermal runaway (fires or explosions).
  • Long lifespan: Typically more than 2,000 cycles.
  • Stable voltage and good resistance to both overcharging and deep discharging, which improves battery longevity.
• These characteristics make LFP batteries ideal for applications such as electric vehicles, solar energy storage, and off-grid systems.

3. 15S

• 15S refers to a 15-series battery pack, which means 15 lithium cells are connected in series.
• With LiFePO4 cells having a nominal voltage of 3.2V, a 15S pack has a nominal voltage of 48V (15 x 3.2V), with a full charge voltage of 57V (3.6V per cell).
• This configuration is often used in 48V power systems commonly found in electric vehicles, solar systems, and energy storage.

4. 150A

• The 150A rating means that the BMS can handle continuous current flow up to 150 amps.
• This high current capacity makes it ideal for applications that require significant power output, such as:
  • Electric vehicles (EVs): For large electric vehicles or high-performance setups, ensuring the battery can provide enough power for acceleration, long-range driving, and heavy-duty usage.
  • High-power renewable energy storage: Such as large off-grid solar or wind systems where high discharge rates are needed to support multiple loads or devices.
  • Heavy-duty applications: Marine systems, RVs, and other industrial energy storage systems that need significant power.
• It ensures the system can support high power demands without compromising the safety or performance of the battery.

5. Same Port

• The “same port” design means that charging and discharging of the battery can be managed through one single port.
• This simplifies the wiring and reduces the complexity of the system, making it easier to integrate into compact or high-power systems.

6. Waterproof

• The waterproof design ensures the BMS is protected from moisture, dust, and other environmental factors that might affect its performance, even in outdoor or marine environments.
• This feature makes it ideal for use in applications that may be exposed to wet or harsh conditions, such as electric boats, off-grid systems in rural or outdoor environments, and electric vehicles used in all types of weather.

Key Features:

• Over-voltage Protection: Prevents the battery pack from exceeding its safe voltage limits, which could lead to cell damage or reduced lifespan.
• Under-voltage Protection: Safeguards against deep discharging, which could otherwise cause cell degradation.
• Over-current Protection: Ensures the system doesn’t draw more current than the battery pack can safely handle, preventing overheating or damage.
• Short-circuit Protection: Immediately disconnects the battery if a short circuit is detected, preventing serious damage or fire.
• Over-temperature Protection: Monitors the temperature of the battery and ensures it doesn’t overheat, which can be dangerous for lithium-ion batteries.
• Cell Balancing: Automatically balances the charge between cells to ensure all cells in the pack charge and discharge at the same rate, optimizing performance and battery lifespan.

Applications:

• Electric Vehicles (EVs): Perfect for larger EVs, electric buses, electric boats, or high-performance electric cars that require high current capacity for acceleration and power demands.
• Renewable Energy Storage: Suitable for high-capacity solar or wind energy storage systems, particularly those that need to support heavy loads or power multiple devices at once.
• Off-Grid Energy Systems: Ideal for large off-grid solar or wind systems in remote locations, ensuring safe and efficient battery operation.
• Marine Applications: The waterproof design makes it perfect for marine battery storage, such as in electric boats or yachts, which can face exposure to moisture.
• Industrial/Heavy-Duty Systems: For powering large industrial applications or systems that require reliable, high-power battery storage.

Summary:

The DALY LFP 15S 150A Same Port Waterproof BMS is an advanced, high-power BMS ideal for high-demand applications requiring significant current output. With 150A continuous current handling, overvoltage and undervoltage protection, waterproofing, and cell balancing, this BMS provides excellent protection for your LiFePO4 battery pack while ensuring safe and efficient energy management.

This BMS is well-suited for electric vehicles, large renewable energy storage systems, and heavy-duty off-grid applications, offering high performance and reliability in a variety of environments.
