Description

  • OVERCHARGE OVERDISCHARGE PROTECTION BOARD: Advanced 5S configuration monitors each cell at 4.25V charging voltage and 2.7V discharge cutoff, forestalling battery damage from voltage extremes while extending your 21V Li-ion pack lifespan through precise voltage management
  • HIGH CURRENT DISCHARGE CAPABILITY: Supports continuous 12A discharge with 30A overcurrent detection and automatic recovery, perfect for power tools and electric devices requiring stable high-current output without overheating or performance drops
  • MULTI-LAYER SAFETY SYSTEM: Integrated short circuit protection responds in 250 microseconds, over- shutoff activates at 70°C, and automatic recovery functions insure your battery pack and connected devices stay protected during unexpected conditions
  • DC CONNECTOR BATTERY MANAGEMENT: Pre-wired DC interface simplifies installation for cell packs, eliminating complex soldering while the compact 62x64mm PCB fits standard battery enclosures for DIY power banks and battery solutions
  • ULTRA-LOW POWER CONSUMPTION: Draws only 20μA during operation and 6μA in sleep mode, preserving battery capacity for actual use rather than wasting energy on the protection circuit itself
