It accepts a 3–6V DC input through USB Type-C and boosts the voltage to 8.4V, the required full-charge voltage for a 2S lithium battery pack. The 4A specification refers to the maximum input current version. According to available product specifications, the corresponding charging current is approximately 2.2A, rather than 4A. ⭐ Key Features Designed for 2S lithium-ion/Li-Po battery packs Suitable for 2 × 18650 cells connected in series USB Type-C input 3–6V DC input Recommended input: 3.7V / 5V Step-up/boost charging circuit 8.4V charging voltage 4A maximum input-current version Approximately 2.2A charging current Automatic recharge function Battery charging protection features Compact PCB design LED charging/status indication Suitable for DIY battery and portable-power projects 📋 Technical Specifications Product Type: 2S Lithium Battery Step-Up Charging Module Battery Configuration: 2S – 2 cells in series Compatible Battery: 3.6V/3.7V Li-ion / Li-Po Nominal Battery Pack Voltage: 7.4V Full-Charge Voltage: 8.4V Input Voltage: DC 3–6V Recommended Input: DC 3.7V / 5V Maximum Input Current: 4A Charging Current: Approximately 2.2A Charging Interface: USB Type-C Charging Mode: Constant-current / constant-voltage Board Size: Approximately 39 × 18 × 6.3mm Operating Temperature: -40°C to +85°C LED Indicators: Charging / fully charged or constant-voltage status 🔋 Charging Performance For the 2S 4A version: USB Type-C 5V → Boost Charging Module → 8.4V → 2S Battery Pack The module draws up to approximately 4A from the input, while the specified charging current is approximately 2.2A. This distinction is important when selecting the USB power adapter. 🔧 Applications 2S 18650 battery packs 7.4V Li-ion battery packs 2S Li-Po battery packs DIY power banks Portable electronics Bluetooth speaker battery systems Robotics projects Solar charging applications Electronic prototyping Portable audio equipment Electric fan projects Type-C rechargeable equipment Custom battery charging systems 🛠️ How It Works The module uses a boost/step-up charging circuit to convert the lower USB Type-C input voltage into the 8.4V charging voltage required for a 2S lithium battery pack. 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
