LI-ION 18650 4S 20A BMS Battery Protection Board 14.4V 14.8V 16.8V

Product Description: LI-ION 18650 4S 20A BMS Battery Protection Board 14.4V 14.8V 16.8V

The LI-ION 18650 4S 20A BMS Battery Protection Board is designed for managing a 4-cell lithium-ion battery pack consisting of 18650 cells. This BMS provides robust protection for your battery pack, ensuring it operates safely within its optimal voltage range, which includes 14.4V, 14.8V, and 16.8V configurations. The 20A current rating makes it suitable for moderate power applications, such as electric bikes, drones, and portable power storage. This protection board safeguards the battery from overcharging, over-discharging, short circuits, and thermal issues, enhancing both the performance and longevity of your battery pack. It also features cell balancing, ensuring that each cell within the pack maintains an equal voltage for better overall efficiency.

Features:

• 4S Battery Configuration: Designed for 4S 18650 lithium-ion battery packs with a nominal voltage of 14.8V, and fully charged voltages of 14.4V or 16.8V, ensuring compatibility with most 4-cell lithium-ion setups.
• 20A Continuous Current: Capable of handling up to 20A of continuous current, which is ideal for moderate-power applications such as drones, power tools, and electric vehicles.
• Overcharge Protection: Prevents overcharging by cutting off the charging process once the battery reaches its maximum voltage, protecting the battery from damage and increasing its lifespan.
• Over-discharge Protection: Automatically disconnects the load when the battery voltage drops too low, preventing deep discharge, which could cause capacity loss or failure.
• Short Circuit Protection: Disables the circuit in case of a short circuit, ensuring that both the battery and connected devices are safe from damage.
• Cell Balancing: Balances the charge of each individual cell to ensure uniform voltage levels across the battery pack, improving the overall performance and lifespan.
• Thermal Protection: Monitors the battery’s temperature, cutting off the system if it overheats, thus preventing thermal runaway and other heat-related risks.
• Wide Voltage Range: Supports 14.4V, 14.8V, and 16.8V configurations, making it flexible for a variety of 4S battery setups.
• Low Voltage Cutoff (LVC): Ensures that each cell does not discharge below a safe voltage level, thus prolonging battery life and ensuring safety.
• Compact and Efficient: Small size and low power consumption make it easy to integrate into custom battery packs for various applications.

Application:

• Electric Vehicles (EVs): Ideal for managing battery packs in electric bikes, scooters, or other electric transportation devices that require moderate current.
• Drones: Perfect for drone battery packs, offering reliable protection for lithium-ion cells while maintaining efficient power management.
• Portable Power Systems: Can be used in portable power banks and solar energy storage systems, ensuring safe charging and discharging of lithium-ion batteries.
• Power Tools: Suitable for high-power tools like drills, saws, and other cordless equipment where a 20A current capacity is adequate for the power requirements.
• Hobbyist and DIY Projects: Ideal for building custom battery packs for DIY electronics, robotics, and other hobbyist projects that require reliable battery management.
• Battery Storage Systems: Useful in creating energy storage solutions, like small-scale renewable energy storage systems or backup power supplies.
