Brief: This video explains the main functions and practical uses of the 1S 3.7V 5A 18650 Li-ion Battery Charging Protection Board Module in a clear, step-by-step format. Learn how this compact BMS safeguards single-cell lithium batteries with overcharge, over-discharge, and short-circuit protection.
Related Product Features:
  • Compact 1S lithium battery protection board designed for single-cell Li-ion/LiPo batteries.
  • Features overcharge protection (cuts off at 4.25V) to prevent cell swelling or leakage.
  • Includes over-discharge protection (stops below 2.5V) to avoid irreversible capacity loss.
  • Short-circuit protection triggers in milliseconds to block excessive current.
  • Over-current protection limits discharge current to a safe 5A threshold.
  • Optional over-temperature protection shuts down operation above 70℃.
  • High-quality components with dual MOSFETs for rapid response to anomalies.
  • Ideal for space-constrained devices like Bluetooth earbuds, smartwatches, and IoT gadgets.
Faqs:
  • What certifications does your battery pack have?
    Our battery packs are certified with ISO9001, ISO14001, UL, BIS, KC, USTC, CE, and CB for reliable quality assurance.
  • Is there a minimum order quantity (MOQ)?
    No limitation - we offer competitive pricing based on order quantity. Sample orders are welcome to test our quality before bulk orders.
  • What is the warranty period and how do you guarantee quality?
    Standard warranty is 12 months (negotiable for special products). Our complete production process ensures quality before shipment.
  • What is the lead time for orders?
    Standard products: 3-4 weeks for samples (depending on cell availability), 5-8 weeks for bulk orders (varies by model and quantity).
  • Can we customize the battery pack with our own logo?
    Yes - our professional R&D team can provide customized solutions according to your requirements.
