⚙️ Key Features
✅ UL2271 Certified
Designed to meet UL2271 certification requirements for electrical systems in light electric vehicles (e‑bikes, scooters), ensuring global safety compliance.
🌡️ Dual NTC Thermal Sensors
Two independent NTC thermistors provide redundant over‑temperature protection, actively monitoring battery cells and MOSFET temperature for enhanced safety.
🔒 Dual ICs for Better Protection
Two protection ICs deliver redundant safety against over‑charge, over‑discharge, over‑current, and short circuits, maximizing reliability.
⚡ 20A Continuous Discharge
20A continuous current capability supports 250W–500W e‑bike motors, providing smooth and reliable power delivery.
🔌 Separated Ports
Independent charge and discharge ports allow optimized current ratings, simplifying wiring and enhancing safety during charging and operation.
💡 LED SOC Indicators
Integrated LED indicators display battery State of Charge (SOC) and charging status, automatically turning off during discharging to conserve power.
🚫 Anti‑Charging Reverse Connection
Prevents damage from incorrect charger polarity, protecting the BMS and battery pack.
🔋 Charging Turn‑Off Discharging
Intelligent logic disables discharge while charging, preventing unsafe simultaneous operation and ensuring safe charging cycles.
