Battery protection board for vacuum cleaner battery packs Key benefits — why you need it Prevents overcharge: automatically stops charging when the battery reaches full voltage, reducing the risk of bulging, thermal events, or fire and extending battery service life. Prevents overdischarge: cuts the circuit when cell voltage drops too low, preserving battery capacity and ensuring the pack can be safely recharged and used again. Limits overcurrent: reacts quickly to excessive current draw to protect internal cell structure and maintain stable vacuum operation under heavy load. Blocks short circuits: instantly interrupts current if a short is detected, preventing damage to the battery and reducing fire risk. Core functions and performance Automatic protection functions: overcharge cutoff, overdischarge cutoff, overcurrent detection with rapid response, and shortcircuit interruption. Reliable operation: designed to protect the battery and the vacuum cleaner by maintaining safe electrical conditions during charging and discharging cycles. Durable electronics: built from standard PCB and electronic components suitable for repeated protection cycles and continuous household or commercial use. Compatibility and application Designed for use with vacuum cleaner battery packs (compatible with typical lithiumbased vacuum batteries). Check physical connector and pack layout to confirm fit before installation. Intended to be integrated into or the protection board of a vacuum cleaner battery pack without altering normal charging or operating procedures. Practical use scenarios Home deepcleaning session: protects the battery when the vacuum draws current during prolonged carpet cleaning, preventing overheating and preserving battery life. Overnight charging: prevents overcharge while the battery remains on the charger, reducing longterm cell stress and extending usable life. Battery storage or infrequent use: stops excessive selfdischarge from damaging cells, ensuring the battery can be safely charged after storage. What it solves Eliminates common batteryrelated failures caused by overcharge, overdischarge, excessive current, or short circuits. Reduces maintenance costs by extending battery lifetime and protecting the vacuum cleaner from electrical damage. Improves user safety and reliability during everyday cleaning and charging. Installation notes Ensure compatibility with your vacuum pack's connector layout and physical dimensions before replacing or installing the board. Follow manufacturer guidance for battery pack disassembly and reassembly to maintain safe operation. This protection board preserves battery health, enhances safety, and maintains consistent vacuum performance by delivering fast, automatic electrical protection across charging and operating conditions.
