Example: 5V Type-C Input → Step-Up Circuit → 8.4V Charging Output → 2S 18650 Battery A 2S battery pack consists of two lithium cells connected in series: 3.7V + 3.7V = 7.4V nominal4.2V + 4.2V = 8.4V fully charged 💡 LED Indicators The module uses status indicators to show the charging condition: CR: Charging OK: Fully charged / constant-voltage stage ⚠️ Important Notes This module is intended for 2S battery packs only. Do not connect a single 18650 cell directly to the 8.4V charging output. The two cells should be properly matched and in good condition. Do not exceed the 6V maximum input voltage. A suitable Type-C power source is required to supply the necessary input current. The 4A rating is the input-current rating, not the battery charging current. The specified charging current for this 2S 4A version is approximately 2.2A. This charging module should not automatically be considered a replacement for a dedicated 2S BMS/protection board. Use appropriate battery protection where required. Check the PCB polarity and connection markings before connecting the battery. Do not short-circuit the input or output. Use properly matched lithium cells for safe and reliable charging. Keep the module adequately ventilated during higher-current operation. 📦 Package Includes 1 × 2S 4A Type-C Step-Up Boost Lithium Battery Charging Module – 8.4V
