🚨 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 properly

Use 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 charging

Correct Battery Connection: Always connect battery balance plug (2S if available) and main wires correctly to module terminals. Reverse polarity may cause damage

Charging 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 chemistries
