2S 4A Type-C Lithium Battery Charging Module – 8.4V Step-Up Boost Charger for 18650 Lipo
[Step UP Buck Converter] 2S 4A Type-C Lithium Battery Charging Module – 8.4V Step-Up Boost Charger for 18650 The 2S 4A Type-C Lithium Battery Charging Module is a compact step-up charging board designed for charging 2-cell series (2S) 18650 Li-ion/Li-Po battery packs. 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
Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output
[Step UP Buck Converter] Type-C PD/QC/AFC Fast Charge Decoy Trigger Module – 5V/9V/12V/15V/20V Fixed Output The Type-C PD/QC/AFC Fast Charge Decoy Trigger Module is a compact USB Type-C power negotiation module designed to request a selected voltage from compatible USB Type-C fast chargers and power banks. It supports QC 2.0/3.0, AFC, PD 2.0 and PD 3.0 protocols, allowing compatible USB-C power sources to provide higher voltage outputs such as 5V, 9V, 12V, 15V or 20V. This module is useful for DIY electronics projects where a USB Type-C PD/QC charger needs to be used as a DC power source for equipment that does not have native USB-C fast-charging support. ⭐ Key Features USB Type-C fast-charge decoy/trigger module Supports PD 2.0 / PD 3.0 Supports QC 2.0 / QC 3.0 Supports Samsung AFC Fixed selectable voltage output Supports 5V / 9V / 12V / 15V / 20V output options Negotiates the required voltage from a compatible charger Suitable for USB-C power banks and PD adapters LED indicators for operating/status indication Compact and lightweight PCB design Useful for DIY power supply and electronics projects Plug-and-play operation with compatible USB-C power sources 📋 Technical Specifications Product Type: USB Type-C Fast Charge Trigger / Decoy Module Input Connector: USB Type-C Input Source: USB-C PD/QC/AFC compatible charger or power bank Supported Protocols: PD2.0, PD3.0, QC2.0, QC3.0, AFC Output Voltage: 5V / 9V / 12V / 15V / 20V Output Type: DC Voltage Selection: Fixed/selectable depending on module version Indicator: LED status indicators Application: DC power conversion and fast-charge voltage triggering 🔧 Applications Converting USB-C PD chargers into DC power supplies Powering DIY electronics projects Arduino and microcontroller projects LED applications Portable electronic equipment DIY laboratory power supplies DC motors and other suitable loads Router/modem power applications where the required voltage matches Powering electronics from USB-C PD power banks Replacing conventional DC adapters with USB-C PD sources 🛠️ How It Works The module does not boost the USB voltage itself. Instead, it communicates with a compatible USB-C power source and sends the required PD/QC/AFC negotiation request. For example, when connected to a compatible PD charger, the module can request: 5V → 9V → 12V → 15V → 20V The charger then provides the negotiated voltage at the module's DC output. ⚠️ Important Notes The connected USB-C charger or power bank must support the required fast-charging protocol and voltage. A standard 5V-only USB charger cannot normally provide 9V/12V/15V/20V through this module. Always verify the selected output voltage with a multimeter before connecting your device. Do not connect a device that requires a lower voltage than the selected output. The module is a trigger/decoy board, not a standalone DC-DC boost converter. Maximum available output power/current depends on the connected USB-C charger/power bank and the module's specifications. Do not short the output terminals. 20V output can damage 5V/9V/12V-only electronics if the wrong voltage is selected. Exact selectable voltages and current capability can vary between board versions. 📦 Package Includes 1 × Type-C PD/QC/AFC Fast Charge Decoy Trigger Module
