Description:
3S 10A Lithium-Ion Battery Protection Board | Full-Spectrum Circuit Safeguard for 3-Cell 18650 Li-ion Battery Packs, Ensuring Stable, Safe Operation while Extending Your Battery’s Overall Service Life.
Features:
✅ Reliable Overcurrent Safety: Fitted with a 0.01Ω high-accuracy current sensing resistor and control IC, it automatically cuts off power when continuous current hits 10A. This effectively stops battery damage from overloads or short circuits, massively boosting the safety of your battery packs.
✅ Overcharge & Overdischarge Protection: Equipped with 4 high-performance MOSFETs, it tracks the voltage of every series-connected cell in real time. It shuts off the charge/discharge circuit immediately once voltage hits the pre-set threshold, preventing battery swelling, capacity loss, or permanent breakdown from improper charging/discharging, and lengthening battery lifespan effectively.
✅ Durable Circuit Base: Made of high-grade FR-4 fiberglass printed circuit board, it boasts excellent insulation, heat resistance, and corrosion resistance. It runs stably even in high-temperature or high-humidity working environments, cutting down circuit failure rates for long-term use.
✅ Smart Cell Balancing Feature: Integrated with a professional balancing control IC, it automatically equalizes the voltage of all 3 battery cells during charging, improving the overall charging efficiency of the full battery pack and maximizing the usable capacity of every single cell.
✅ Easy Installation Design: Pre-marked clearly labeled soldering pads (B+, B1, B2, B-, P+, P-) with a tin-plated surface allow for direct soldering with no extra surface prep, cutting down your assembly work. It works perfectly for both DIY battery projects and industrial mass battery pack production.
