Battery protection board for vacuum cleaner battery packs — designed to keep your battery safe, reliable, and longer lasting. Key benefits Prevents overcharging: Automatically stops charging when the battery reaches its safe voltage, avoiding battery swelling, overheating, or fire risk and extending overall battery life. Prevents overdischarge: Cuts the circuit when battery voltage drops too low, protecting cell health and ensuring the battery can be recharged and used again reliably. Limits overcurrent: Reacts quickly to excessive current draw to prevent damage to the battery's internal structure and maintain stable vacuum performance. Stops short circuits: Immediately interrupts current flow if a short is detected, reducing the chance of battery failure, damage, or fire. Core functions and performance Fast, automatic protection actions that activate without user intervention to maintain safety and battery health. Reliable circuit cutoff for fault conditions (overcharge, overdischarge, overcurrent, shortcircuit) to protect both the battery pack and the vacuum cleaner. Designed to prolong battery service life by preventing common electrical stresses that degrade cells. Compatibility and physical attributes Intended for use with battery packs in cordless vacuum cleaners and similar portable cleaning devices. Compact PCB form factor with standard connection points for integration into vacuum battery assemblies. Built from quality electronic components to deliver consistent protective behavior and longterm reliability. Typical use scenarios Home cordless vacuum: Protects the vacuum's battery during frequent charging and heavy cleaning sessions. Professional/utility cleaning equipment: Maintains battery health in use environments and prevents downtime caused by battery faults. Portable cleaning for travel or vehicle use: Ensures safe charging and operation when batteries are charged or discharged repeatedly. Why this protection board matters Provides essential, automatic safeguards that reduce safety risks, preserve battery capacity, and help ensure your vacuum cleaner operates reliably over time.
