Constant current charging with LED indicator: Red light during CC stage, switches to green or off when fully charged. Suitable for Li‑ion battery packs (nominal 3.6V/3.7V, full charge 4.2V per cell).
Core Features of Constant Current Li‑ion Battery Charger
CC/CV charging curve: Constant current fast charging → constant voltage trickle charging, effectively protects battery life and prevents overcharging.
Smart LED indicator: Red light during charging, turns green or off when fully charged – charging status at a glance.
Multiple safety protections: Overvoltage (OVP), overcurrent (OCP), short circuit (SCP), over temperature (OTP), optional reverse polarity protection.
Wide voltage input: 100-240V AC, universal use.
Full certifications: CCC/CQC/UL/FCC/CE/KC/UKCA/PSE/CB/RoHS, meeting major global market access requirements.
Housing material: PC flame‑retardant material, ultrasonic welding, sturdy and durable.
Selection & Customization Advice
Strict voltage matching: Output voltage = number of cells in series × 4.2V (e.g., 2‑cell Li‑ion must use 8.4V charger).
Current selection: Recommended 0.2C~0.5C of battery capacity (e.g., 2000mAh battery choose 1A charger). Higher current reduces charging time but requires battery support.
Connector customization: DC plug types (5.5×2.1/2.5, 3.5×1.35, Type‑C, magnetic connector, aviation plug), cable length (0.5m~2m) can be customized.
Plug options: China, US, EU, UK, Japan, Korea, etc. – fixed or interchangeable plugs.
