Key benefits Protects battery safety and extends service life by preventing common electrical faults that damage cells. Keeps your vacuum cleaner reliable and ready to use by automatically disconnecting the battery when risk conditions occur. Reduces fire, swelling, and performance loss risks through fast, automatic protective actions. Core functions Overcharge protection: Stops charging when the battery reaches full capacity to prevent swelling, overheating, or fire caused by overcharging. Overdischarge protection: Automatically cuts off the circuit when battery voltage falls too low to prevent deep discharge and preserve battery capacity for future charging. Overcurrent protection: Detects excessive current draw and quickly interrupts the circuit to prevent heat damage and protect the battery's internal structure. Shortcircuit protection: Immediately disconnects current on detection of a short circuit to avoid catastrophic damage and improve user safety. Performance and reliability Fastresponse protection logic ensures rapid cutoff under fault conditions to minimize damage. Automatic, maintenance operation with no user intervention required during normal use. Designed to maintain battery performance over repeated charge/discharge cycles, improving longterm reliability of the vacuum cleaner. Compatibility and form Intended for use with vacuum cleaner battery packs and compatible charging systems; functions as a battery protection board for cordless vacuum applications. Electronic protection board format integrates with standard battery modules without altering battery chemistry or cell configuration. Practical applications Home cordless vacuum: Prevents battery damage during everyday charging and heavy cleaning sessions, keeping suction performance consistent. Commercial or workshop vacuum use: Protects dutycycle batteries from overcurrent and shortcircuit events during intensive cleaning tasks. Offseason or storage: Prevents deep discharge when the vacuum is stored for long periods, making later recharging safe and reliable. Why choose this protection board Solves real safety problems (overcharge, overdischarge, overcurrent, shortcircuit) that directly affect battery life and user safety. Delivers clear, automatic protection that reduces the need for manual monitoring and lowers the risk of costly battery replacement. Integrates with vacuum cleaner battery systems to maintain stable, predictable operation without changing user charging habits.
