LI-ION 18650 4S 40A BMS Battery Protection Board 14.4V 14.8V 16.8V

Product Description: LI-ION 18650 4S 40A BMS Battery Protection Board 14.4V 14.8V 16.8V

The LI-ION 18650 4S 40A BMS Battery Protection Board is a highly efficient and reliable battery management system designed for 4-series (4S) 18650 lithium-ion batteries. This protection board is essential for ensuring the safe operation of your lithium-ion battery pack by preventing overcharging, over-discharging, and short-circuiting. Supporting battery voltages of 14.4V, 14.8V, and 16.8V, it is ideal for applications requiring stable and consistent power, such as power banks, electric vehicles (EVs), and other high-power devices. With a robust current rating of 40A, this BMS can handle high-power demands, making it perfect for larger battery configurations. Its efficient circuitry monitors and balances the cells to ensure that each cell is charged and discharged evenly, prolonging battery life and ensuring optimal performance. This protection board is a must-have component for any project that involves 18650 batteries, offering both safety and reliability.

Features:

• 4S Configuration: Designed for 4-series 18650 lithium-ion batteries, offering a nominal voltage of 14.8V with a full charge voltage range of 16.8V.
• High Current Rating: Capable of handling up to 40A, making it suitable for high-power applications like electric vehicles, drones, or power banks.
• Cell Balancing: Includes built-in cell balancing to ensure all battery cells are charged evenly, improving battery life and performance.
• Overcharge Protection: Prevents battery cells from being charged beyond their safe voltage limits (typically 4.2V per cell), protecting the cells from damage.
• Over-Discharge Protection: Automatically disconnects the load if the battery voltage drops too low (typically 3.0V per cell), preventing deep discharge and prolonging battery life.
• Short Circuit Protection: Safeguards the battery pack by cutting off the connection if a short circuit is detected, protecting both the battery and the load.
• Temperature Protection: Monitors battery temperature and cuts off power in the event of excessive heat, ensuring safe operation.
• Low Voltage Cut-Off: The BMS stops discharging the battery once it reaches a certain low voltage, preventing damage to the cells.
• Compact Design: A compact and lightweight design that makes it easy to integrate into custom battery packs for various applications.

Applications:

• Electric Vehicles (EVs): Perfect for use in electric bikes, scooters, and other EVs that require a reliable power management system for 4S 18650 battery packs.
• Power Banks: Ideal for large capacity power banks that need a safe and efficient way to manage multiple 18650 cells.
• Drones: Used in drone batteries to ensure safe charging and discharging, extending the life of the battery pack.
• Solar Energy Storage: Suitable for use in solar battery systems that rely on 18650 cells for storing energy.
• RC Hobby Projects: Perfect for remote control (RC) vehicles and robots that need a stable and balanced power supply from 18650 cells.
• Portable Electronics: Can be used in other portable devices requiring high-capacity batteries and reliable power management.
