DESCRIPTION :

3S 11.1V 25A LI-ION Battery Protection Board BMS

A 3S 11.1V 25A Li-Ion Battery Protection Board (BMS) is an electronic circuit designed to safeguard a lithium-ion battery pack consisting of three cells connected in series. It monitors the battery's voltage, current, temperature, and state of charge (SOC) to prevent overcharge, over-discharge, short circuit, and overcurrent conditions.

Key Features:

• Voltage protection: Prevents the battery from being overcharged or over-discharged, which can lead to damage or safety hazards.
• Current protection: Limits the charging and discharging current to safe levels, preventing excessive heat generation and potential thermal runaway.
• Temperature protection: Monitors the battery's temperature and shuts down the circuit if it exceeds safe limits, preventing thermal runaway and fire hazards.
• Short circuit protection: Detects and interrupts the circuit if a short circuit occurs, preventing damage to the battery and external components.
• Overcurrent protection: Protects the battery from excessive current draw, which can lead to overheating and damage.
• Under-voltage protection: Prevents the battery from discharging to dangerously low voltages, which can damage the cells and reduce their lifespan.
• Balance function: (Optional) Ensures that all cells in the battery pack are balanced, preventing uneven charging and discharging, which can lead to premature failure.

Applications:

• Power tools: Drills, saws, grinders, etc.
• Electronic devices: Cameras, video recorders, portable speakers, etc.
• Medical equipment: Portable devices for monitoring and diagnostics.
• Hobby and DIY projects: RC cars, drones, robots, etc.
• Emergency lighting: Backup power for LED lights and flashlights.

Specifications:

• Input voltage: 11.1V (nominal)
• Output current: 25A (continuous)
• Charging current: Typically 5A-10A
• Protection functions: Overcharge, over-discharge, short circuit, overcurrent, temperature
• Operating temperature: -20°C to +85°C
• Storage temperature: -40°C to +85°C
• Dimensions and weight: Vary depending on the specific model and manufacturer

Please note that the specifications may vary depending on the specific model and manufacturer. It is important to choose a BMS that is compatible with your battery pack and application requirements.
