18650 DC-DC Step up 3.7V To 4V-18V 2A + Charge/Discharge Module Type-C رافع جهد و شاحن ليثيوم

The 18650 DC-DC Step up 3.7V To 4V-18V 2A + Charge/Discharge Module Type-C is a compact combined boost converter and battery management module designed for use with a single-cell 18650 lithium battery. It converts the nominal 3.7V cell voltage to a regulated output between 4V and 18V while supporting up to 2A output current, and integrates charge/discharge control to simplify portable power designs. Key features include a boost conversion stage that produces a selectable output voltage in the 4V–18V range, an integrated charge/discharge control stage for battery management, and a USB Type-C connector for power input or charging. The module reduces wiring complexity by consolidating step-up conversion and charging functionality onto one board, making it suitable for DIY electronics, prototyping, repair work, and portable projects where a regulated higher voltage is required from a single 18650 cell. Applications include powering small DC loads from a single 18650 cell, bench testing and development, portable lighting, small motor drives, and battery-backed electronics. The module is intended for users familiar with lithium battery handling and basic electronics assembly; it is a component designed for integration rather than a finished consumer product. Safety and usage notes: use only appropriate 18650 cells and follow established lithium battery safety practices. Verify correct wiring and polarity when connecting the cell and external load, observe the module's rated input and output limits, and provide adequate cooling during continuous high-current operation. This product requires user knowledge for safe installation and operation.
