12.6V 1A 3S Lithium Battery Charger – CC/CV Intelligent Wall Adapter for 3-Cell Li-ion & LiPo Packs

Overview 

Keep your custom 12V battery configurations healthy and topped up with our 12.6V 1A 3S Smart Lithium Battery Charger. Engineered specifically for 3-cell (3S) series-connected Lithium-Ion or Lithium-Polymer battery arrays, this wall brick uses a smart 2-stage charging algorithm: Constant Current (CC) fast-charging safely restores bulk capacity, while Constant Voltage (CV) trickles the final percentages to prevent dangerous cell over-voltage conditions. The integrated dual-color LED light gives you immediate visual feedback so you know exactly when your hardware is ready to deploy.

Key Features 

• Smart CC/CV Charging Profile: Maximizes battery cycle life by applying high current initially, then smoothly decreasing output as the cells hit their 4.2V per-cell peak.

• Auto-Cutoff Protection: Zero overcharging hazard. The charger automatically cuts off output energy the instant the 12.6V total pack limit is satisfied.

• Dual-Color LED Indicator: No display screen needed. The built-in LED shines solid Red while active charging is in progress, and flips to solid Green when full or idle.

• Robust Hardware Safety: Internal circuitry guards your workplace against short circuits, over-current draws, and inverted battery polarity feedback.
