⚙️ Key Features
🔒 Dual ICs for Enhanced Protection
Two independent protection ICs provide redundant safety against over‑charge, over‑discharge, over‑current, and short circuits, ensuring maximum reliability.
⚡ 25A Continuous Discharge
25A continuous current capability supports high‑power 750W–1000W e‑bike motors, delivering robust and consistent power.
🌡️ NTC Over‑Temperature Protection
Integrated NTC thermistor monitors battery temperature in real time, preventing overheating and extending battery life.
🔌 Separated Ports
Independent charge and discharge ports allow optimized current ratings – dedicated 5A–25A charging and 25A discharging – simplifying wiring and enhancing safety.
💡 LED SOC Indicators
Power SOC LED indicators provide clear visual feedback on battery state of charge and charging status, automatically turning off during discharging.
🚫 Anti‑Charging Reverse Connection
Protects the BMS and battery from damage due to incorrect charger polarity, ensuring safe operation.
🔋 Charging Turn‑Off Discharging
Intelligent logic disables discharge while charging, preventing unsafe simultaneous operation and protecting both battery and charger.
✅ UL Certified
Designed to meet UL/ISO/TUV certification requirements, guaranteeing compliance with global safety standards for e‑bike battery systems.
