48V / 52V Intelligent Lithium-Ion Fast Charger Matrix 

 Smart 3-Stage Power Supply (54.6V & 58.8V Output) for Electric Bicycles, Scooters, and Commuter Mopeds

Keep your ride ready for the road. Our 48V/52V Intelligent Lithium-Ion Fast Charger Series provides a highly reliable, cost-effective power supply designed for standard electric bikes, stand-up commuting scooters, and light electric vehicles.

Built to service both 13S (48V Nominal) and 14S (52V Nominal) lithium battery blocks, this smart charger eliminates slow, stock charging bottlenecks by offering multi-amperage rapid current curves up to 5.0 Amps inside a lightweight, durable housing.

Equipped with automated 3-stage smart charging logic, it protects your battery cells during every cycle, transitioning seamlessly from bulk current to cell balancing and finishing with an automated trickle shut-off to prolong your overall battery lifecycle.

🚀 Key High-Performance Features

• Dual Voltage Adaptability Profiles: Precision calibrated to deliver the exact voltage thresholds required for modern e-mobility configurations:

  • 48V Battery Settings: Delivers a strict 54.6V peak output voltage line for 13S packs.

  • 52V Battery Settings: Delivers a strict 58.8V peak output voltage line for 14S packs.

• Intelligent 3-Stage Charging Algorithm: Maximizes capacity retention by cycling through Constant Current (CC), Constant Voltage (CV), and a gentle 170mA Trickle phase to eliminate risk of cell over-saturation.

• Automated Battery Pulse Repair: Delivers a low-amperage 600mA to 800mA pulsing repair current to safely condition deeply discharged cell rows back up to safe working voltage minimums.

• Intuitive LED Status Indicator: Take the guesswork out of your staging area. A clear Red Light indicates active high-amperage charging is underway; a solid Green Light signals a completely balanced, fully charged pack.

• Global Grid Input Sourcing: Fully compatible with universal AC power lines (100V to 240V AC at 50/60Hz). We match your shipping destination at checkout to ensure you receive the proper wall connection (US, EU, UK, or AU plug standard).

🛡️ 5-Way Intelligent System Protection Matrix

Formulated without any hazardous chemical compounds of regulatory concern (High-concerned chemical: None), the internal hardware features a multi-tier defense network:

1. Short-Circuit Automatic Cutoff: Disables active current paths instantly if positive and negative terminals bridge.

2. Over-Current Protection (OCP): Regulates the charge threshold strictly to your pre-selected 2A, 3A, or 5A limit.

3. Over-Voltage Protection (OVP): Ceases power transfer the moment cells hit the absolute 54.6V or 58.8V maximum ceilings.

4. Reverse Polarity Protection: Protects internal circuitry if wires are crossed during installation.

5. Smart Thermal Fold-Back: Monitors internal operating states. If internal temps cross 85°C, the charger automatically shuts off. It opens back up automatically once the internal core cools down safely past 75°C.
