4S 100A LiFePO4 Battery Balance Charging Protection BMS Module

• Nominal Voltage: 12.8V (4S configuration, 3.2V per cell)
• Max Voltage: 14.6V (3.65V per cell, full charge)
• Min Voltage: 11.2V (2.8V per cell, low voltage cutoff)
• Rated Discharge Current: 100A continuous (suitable for high-power applications)
• Peak Discharge Current: 200A (for short duration)
• Over-voltage Protection: Disconnects charging when voltage exceeds 14.6V (3.65V per cell)
• Under-voltage Protection: Disconnects charging/discharging when voltage drops below 11.2V (2.8V per cell)
• Operating Temperature Range: -20°C to +60°C (for safe operation in various environmental conditions)
• Balancing Method: Passive cell balancing (ensures equal charge across all cells)
• Over-temperature Protection: Protects the battery from excessive heat by halting charging or discharging if the temperature exceeds safe limits.
• Short-circuit Protection: Disconnects battery in case of a short circuit to prevent damage.
• Weight: Varies depending on the size and design of the module.
• Connector Type: Typically includes connectors for easy integration with the battery pack, simplifying installation and setup.

Applications:

• Electric Vehicles (EVs): Ideal for use in electric vehicles like electric cars, electric bikes, e-scooters, and other transportation systems that require high discharge currents.
• Energy Storage Systems: Suitable for large-scale energy storage applications such as off-grid solar systems, battery backup solutions, and residential or commercial energy storage systems.
• Portable Power Systems: Used in portable power stations, outdoor power equipment, and other battery-powered devices that need reliable power delivery.
• Power Tools: Can be used for high-power cordless power tools like drills, saws, and other heavy-duty equipment.
• UPS (Uninterruptible Power Supply): Ensures the safe and efficient operation of uninterruptible power supplies (UPS) that use LiFePO4 battery packs.

Benefits:

• Safety and Protection: Provides comprehensive safety features like over-voltage, under-voltage, over-current, short-circuit, and over-temperature protection, ensuring the safe operation of the battery pack and connected devices.
• High-Current Capacity: With support for up to 100A continuous discharge, this BMS is suitable for high-power applications where substantial energy output is required.
• Battery Longevity: The passive balancing feature helps extend the lifespan of the LiFePO4 battery pack by ensuring that all cells charge and discharge evenly, preventing individual cell degradation.
• Temperature Management: The temperature sensors protect the battery pack from overheating or exposure to extreme temperatures, preventing thermal runaway or cell damage.
• Compact and Reliable: Despite its high current capacity, the BMS is designed to be compact and efficient, fitting into a wide range of battery pack designs while maintaining reliability and durability.
