48V E-Bike Graphene Battery Charger – LED Display & Auto Shut-Off

48V E-Bike Graphene Battery Charger with LED Display & Intelligent Pulse Repair

Keep your electric bike or scooter powered and ready with this high-performance 48V 12Ah/20Ah Graphene Battery Charger. Featuring a 6-stage LED status display, automatic overload shut-off, a built-in cooling fan, and intelligent pulse repair technology, this charger is engineered for reliable, efficient, and safe charging every time. Made in Mainland China.

Key Features

• 6-Stage LED Power Display: Six built-in LED indicators show real-time charging progress — from power connected through 20%, 40%, 60%, 80%, and full charge — so you always know exactly where your battery stands.
• Intelligent Pulse Repair Technology: The integrated pulse repair circuit reactivates dormant graphene battery cells and corrects minor capacity loss, helping to extend your battery's overall service life and reduce the need for costly replacements.
• Automatic Overload Shut-Off: Built-in smart protections automatically cut power in the event of overcharging, overcurrent, overheating, or short circuit — keeping both your battery and charger safe.
• Active Cooling Fan: An internal cooling fan maintains optimal operating temperature during charging, ensuring consistent performance and long-term reliability.
• Durable ABS Shell: The high-quality ABS plastic housing offers excellent scratch, drop, and deformation resistance, protecting internal components from the knocks of everyday use.
• Reinforced Tangle-Resistant Cable: Power cord connectors are built with wear-resistant reinforcement for superior bending and tensile strength, preventing broken wires or poor contact over years of repeated use.
• Silent Operation: Runs completely quietly during charging — perfect for overnight top-ups without any noise disruption.
• 1-Year Warranty: Backed by a 12-month warranty for complete peace of mind.
