उत्पाद विवरण


The 4S Lithium Battery Protection Board is a specialized safety and performance component exclusively engineered for 4-cell series (4S) lithium battery packs, covering Li-ion, Li-polymer, and LiFePO4 chemistries. As a critical “safety guardian” for 4S battery systems, it prevents irreversible damage, mitigates safety hazards (e.g., thermal runaway), and extends battery lifespan—making it indispensable for high-voltage consumer electronics, industrial equipment, and mid-power portable energy solutions.​
Tailored Protection for 4S Battery Packs​
Optimized for 4S configurations (nominal voltage: 14.8V for Li-ion, 12.8V for LiFePO4), this board delivers multi-dimensional safeguards calibrated to 4-cell characteristics:​
  • Overcharge Protection: Triggers when any single cell exceeds 4.25V (Li-ion) or 3.65V (LiFePO4), instantly cutting off charging current to avoid cell swelling, electrolyte leakage, or thermal risks—critical for 4S packs where voltage accumulation amplifies overcharge hazards.​
  • Undervoltage Protection: Shuts down discharge if any cell drops below 2.5V (Li-ion) or 2.0V (LiFePO4), preventing permanent capacity loss that plagues 4S packs when “weak cells” drag down the entire system.​
  • Overcurrent & Short-Circuit Protection: Blocks high currents (up to 35A, model-dependent) caused by short circuits or overloads (e.g., high-power tool startups), shielding both the 4S battery pack and connected devices from burnout.​
  • 4-Cell Balancing: Automatically equalizes voltage across all 4 cells during charging, eliminating uneven charge distribution (a common issue in multi-cell packs) and ensuring each cell operates at peak efficiency—avoiding “capacity bottlenecks” from undercharged cells.​
High Precision & Low Idle Power Drain​
Equipped with high-sensitivity voltage detection chips, the board monitors each of the 4 cells with ±2mV precision, ensuring timely and accurate protection responses even for subtle voltage fluctuations. Its ultra-low static current (<10μA) minimizes idle power consumption, preventing unnecessary capacity loss when the 4S pack is stored or not in use—critical for backup devices like emergency lights or portable storage units. Additionally, it features a auto-recovery function: once fault conditions (e.g., overcurrent) are resolved, it resumes normal operation without manual reset, enhancing user convenience.​
Broad Compatibility & Rugged Design​
This protection board supports 4S battery packs with capacities ranging from 1500mAh to 30000mAh, adapting to diverse power needs. It is fully compatible with standard 4S chargers and discharge devices, and works seamlessly with Li-ion, Li-polymer, and LiFePO4 chemistries—eliminating the need for multiple protection boards for different battery types. Constructed with a flame-retardant PCB board and industrial-grade components, it withstands extreme temperatures (-20°C to 85°C) and mechanical vibration, making it reliable for harsh environments like construction sites (electric tools) or outdoor adventures (camping power stations).​
Versatile High-Voltage Applications​
Ideal for 4S battery-powered devices requiring stable high voltage:​
  • Consumer electronics: 4S drone batteries (for longer flight time), high-capacity power banks (fast charging support), and professional LED work lights;​
  • Industrial equipment: 4S cordless power tools (e.g., heavy-duty drills, angle grinders), IoT sensor arrays (high-power transmission), and small medical devices (e.g., portable oxygen concentrators);​
  • Recreational & mobility gear: 4S electric scooters, RC cars/boats (high-torque performance), and camping portable fridges.
