Critical Selection & Usage Guide (READ BEFORE PURCHASE)：Select Correct Model: You MUST choose the 2S version (8.4V) or 3S version (12.6V) that matches your battery configuration. Wrong version will not charge properlyUse QC Charger for Full Performance: To achieve max 1.5A charging current and 15W power, you MUST use a Quick Charge compatible USB charger. Standard 5V/2A charger will result in slower chargingCorrect Battery Connection: Always connect battery balance plug (2S if available) and main wires correctly to module terminals. Reverse polarity may cause damageCharging Current Adjustment: Charging current can be adjusted via onboard potentiometer; recommended to set according to battery capacity (e.g., 1C charge)Battery Type Compatibility: For Li-ion or Li-Po batteries only. NOT suitable for lead-acid, NiMH, or other chemistriesSpecifications：Input Interface: Type-C (Supports QC Fast Charge)Charging Power: 15W MaxMax Charging Current: 1.5A (Adjustable via potentiometer)Supported Configurations:2S Version: 2S Li-ion (8.4V) | Onboard Hardware Balancing3S Version: 3S Li-ion (12.6V)Protections: Input OVP/UVP, Output OCP/OVP/SCP, TimeoutEfficiency: Up to 94% (Synchronous Switching)Operating Temperature: -20°C to +85°CPackage Includes：1 × Type-C 2S or 3S Battery Charger Module (Shipped according to selected model)
